Want to Study Rocks in College? Here’s What You Need to Know

Geology is the scientific study of rocks. Rocks are essential to human civilisation because they contain minerals and metals that we use in our everyday living. Petrology, on the other hand, is the specialised study of rocks and is an important component of Geology.

Geologists make an in-depth study of rocks because they contain clues about the past of the Earth. From these clues, scientists can formulate a historical record of the planet and trace the events that happened long before the humans existed.

Graduate programs in Geology are designed for training students in a career working in the fields of water, energy, environmental services, soil and education. These degrees include field experiences with water and soil analysis and the examination of rock formations. Graduate schools in Geology help prepare the students for potential work in construction, government, education and resource management. With a geology degree, you are well prepared for a career as a geologist.

You can select from various kinds of geology graduate schools. The programs for geology offer online or on-campus classes. There are part-time and full-time course loads as well. The programs at the Masters in Geology level are called Master of Earth and Environmental Sciences degree or a Master of Geoscience degree. If you want to earn a degree in higher learning, you can aim for a doctorate geology programs like Doctorate in Earth Science or a certificate program like Geoscience of Subsurface Exploration Appraisal and Development Graduate Certificate (GeoSEAD). You can choose your graduate program for geology that will match your career goals.

There are two learning institutions in Mexico where you can get a Master’s degree in Geology. These are Universidad Autonoma de Nuevo Leon and Universidad de Sonora.

Tagged as one of the best colleges in Mexico, Universidad Autonoma de Nuevo Leon is located in Linares, Mexico. You can complete a full degree and graduate with a Master’s degree in Geology. Likewise, in Universidad de Sonora, located in Hermosillo, Mexico, you can also graduate with the same academic qualifications. You will have to put in a personal request for the details of their academic program on their website. In these public universities, the main language of instruction is in Spanish.

Other colleges you can attend to get an undergraduate degree in the study of rocks is in Universidad Iberoamericana, Mexico City and Puebla. The University’s main campus is located in the Santa Fe suburbs of Mexico City. The private institution is founded in 1943 and offers various degree programs in different academic disciplines. There are three terms when you can enter the academy: academic year, spring semester and fall semester.

Why choose a university or college in Mexico? Mexico claims to have the second biggest Latin America economy next to Brazil. It is included in TIMBI, the group of countries comprised by Turkey, India, Brazil and Indonesia. These are countries that are very progressive and are following closely to nations called BRICS, which are the fastest growing economies of the world. With Mexico’s growing economy is the rise of a higher education system, making the overseas study to this country a worthy consideration.

Forget IPads, a Better Hobby for Your Children Is Rocks

It is sad seeing children who are no longer interested in the things we used to do when we were younger. There was a time when children loved the outdoors. They would rather play with other kids and have fun even if it means they would be very messy at the end of the day.

Today, most kids are attached to their electronic devices. They would rather play with their favorite games using their iPads or video gaming consoles than go out and experience the real world. They have rich experience when it comes to virtual reality but they are totally detached from the real life.

This is sad considering that there are a lot of values that kids can learn by going out of the house to play. This is why it is important for parents to motivate their children to try something new. There is nothing wrong in reintroducing activities to kids today those that used to be popular in the past.

Try collecting rocks

One of the most popular hobbies for kids before was collecting rocks. The reason why it was extremely popular was because of the excitement that children felt in search of specific rocks. There might be a lot of rocks out there, but not all of them are worth collecting.

They have to find specific types of rocks and classify them accordingly. Storing and organizing these rocks is also an exciting thing to do.
In collecting rocks, there are various factors that have to be considered. It includes size, colour, shape and texture. Some of them are a major stand out as they don’t look like the rest. The ones that have unique shapes and properties must be included in the collection.

The best part about collecting rocks is that kids are given the chance to also travel outside their homes. They need to go elsewhere in search of more interesting rocks. Otherwise, the same types of rocks will be collected and it won’t be exciting at all. Places like quarries, roads, construction sites and beaches are among the best places to search for rocks. Just make sure that your kids are safe as they visit these places. You should also have the necessary permits to look into certain areas for rocks.

There are certain areas where people are not allowed to search for rocks. This includes national parks, monuments and private properties. Although there are a lot of interesting finds in these areas, it is best to just avoid them.

The necessary tools

Collecting rocks is not easy. If your kids really want to take it seriously, they need to have the basic tools. This includes a magnifying glass for closer inspection of the rocks. There should also be a hammer with two ends- blunt and pick. This tool is essential for breaking the rocks and collecting specimens. Safety glasses must also be worn to avoid damaging the eyes. Gloves must also be work for protecting the hands.

In collecting the samples, you must also bring newspapers to wrap the rocks. Markers are also important for labeling the samples and a bag where the collected samples are temporarily stored.

What to do after collection

After getting the samples back, the next step is to identify them. They have to be grouped based on properties. There are different types of rocks and they can be grouped as igneous, sedimentary or metamorphic. In a way, it teaches kids scientific lessons.

Once the rocks have been identified and classified, they must be properly labeled so they won’t be mixed up. You should also start cataloging them so that the next time you need certain information or you have to retrieve the rocks, it would be easy.

Finally, the rocks must be displayed. This is a proud moment for your child who has worked really hard to get the entire process done.

Important lessons

Collecting rocks will teach kids a lot of lessons. They will learn how to be patient since they won’t find anything special all the time. They will also learn important scientific lessons. As they study in an actual science class, they will be more prepared. Most of all, they will learn to make the most of their childhood. Collecting rocks can be very fun. It won’t be the same experience as just sitting on the couch while playing video games.
As a parent, you need to do everything possible to give your kids only the best. Check out BabyGearGuide for more information on products and apparels your baby would need most. You can count on them for quality baby products.

Which Footwear Should You Choose for a Long Hike Searching for Rocks?

wanderer-455338_640Plantar fasciitis is a common problem especially among middle-aged people who are busy with work or athletics. This usually comes with heel pain. It is due to repeated strain that may cause tears on the ligament and become really painful. This may also lead to swelling for severe cases. It may also happen if you keep searching for rocks over long distance.

There are a lot of reasons why this could happen. You might be wearing really high heels. They are considered plantar fasciitis shoes because they force your feet to roll inward when you walk and make you feel a lot of pain. You may also have a really active lifestyle because you are a runner or your job requires you to walk or run a lot. This problem could be serious and could cause extreme pain.

Solving the problem

The best way to end this problem is to choose the right pair of shoes. Aside from aesthetics, the main quality to look into is comfort. You have to feel really comfortable with what you are wearing. You need to choose shoes with arch support or cushioned sole. You can also try using heel cups or inserts just to provide support for your feet and lessen the impact of using heels. If this does not work, you have to consult your doctor. There are people who have developed a more severe problem because they have been trying to ignore the pain and still push through with the same shoes for a very long time. You can put on your new shoes and try hiking next time to see if there is a difference in how you feel.

At night, it helps if you place ice cubes on a basin of water where you can put your feet to rest. It will at least help alleviate the pain. This is not the best solution, but you can give it a try. There are also some creams that you can apply on your feet to make it feel cold and relaxed. Again, seeking for your physician’s help is the best way to put an end to this especially if this has been going on for a while now. You don’t think it is a serious problem but it could be. Get help as soon as possible.

Can Chainsaws Cut through Rock?

can-chainsaws-cut-through-rockThere are different types of chainsaws. They come in different sizes and weight. They also serve different purposes. Usually, we imagine them being used to cut wood. They cut huge trees and trim them down to smaller pieces. Smaller chainsaws are easier to use, but they are not meant for heavy duty purposes. They are also more suitable for sculpting because they are easier to handle. Bigger chainsaws are reserved for big and heavy tasks such as cutting old and thick trees.

When it comes to wood, it is easy to imagine using chainsaw. It is sharp enough to cut trees into smaller pieces and make them more refined. However, you might not immediately think of them if you are to cut rock. The bigger question is, can chainsaw cut through rock? Will it not break apart? Will rocks not fly away once cut and potentially injure someone?

The truth is that there are chainsaws that can cut through rocks, but not all of them are meant for the said purpose. Some of them are only useful for trees. Once used for rocks, they can easily break apart.

Concrete chainsaws

These are common nowadays. It is true especially since there are areas in which a different concrete size or shape would be necessary. It can’t be broken down further except if a concrete chainsaw is used. This is perfect for cutting concrete as it would cut through without breaking the concrete into smaller pieces. It will also not damage the chainsaw or make blades dull. They are meant for such purpose.

Chainsaws for rocks

Chainsaws meant to cut through concrete are more delicate. They only work when used with softer rocks. Harder rocks on the other hand would require a different kind of chainsaw. It has to be more powerful. It should cut the stone into smaller pieces according to the exact shape that you would like it to be. They are also sharp and extremely dangerous when used by people who are not trained to handle it.

There are other chainsaws that are more suitable for harder minerals like diamond. Yes, the hardest mineral can still be cut further using a chainsaw which is meant for that purpose. It is extremely difficult to use and only those who have trained to use it can do it with ease. Otherwise, it could affect the quality of the diamond.

The best choice

When it comes to price, it also varies depending on the model that you have chosen and the size of the chainsaw. You might also want to read chain saw reviews for more information on the best chainsaw to buy.

You can also look for references online and read the specifications for each model before closing the deal. Most of all, you have to compare the options first by looking at the price, specs and reliability of the brand. Once you have compared the options and found the best one on the list, you can go ahead and seal the deal.

How Minerals Make Your Water Hard in the UK

how-minerals-make-your-water-hard-in-the-ukA major part of the United Kingdom receive hard water. It occurs due to the abundance of sedimentary rocks in the entire UK. This accounts for about 13 million households in the country. Rainwater that fills boreholes, reservoirs, rivers and streams where water supply come from is naturally soft. But since water is a very good solvent, it erodes parts of soft rocks like limestone and chalk, picking up the magnesium and calcium mineral contained in the rocks. These and small amounts of other minerals make for hard water.

There are some parts in the UK that do not receive hard water, though. Due to the regions’ geology, what they have is soft water, such as the regions located to the west and north of the UK. The development of wider networks of water distribution however, there are parts of the UK that formerly get soft water, now are supplied with hard water.

Hard water map

Lincoln, London, Brighton, Bristol and Southampton, including parts of Birmingham have hard to very hard water. Manchester and many parts of Birmingham as well as Newcastle upon Tyne receive slightly hard to moderately hard water. The rest of the country generally receive soft and moderately soft water. The abundance of soft rocks in several areas of the UK is what contributes to the water hardness in the country. Those areas with hard rocks are also the areas that receive soft water.

The concentration of multivalent cations (positively charged metal complexes) determine the hardness of the water. Most common minerals found in the water are magnesium bicarbonate and calcium bicarbonate. These minerals contribute to the temporary hardness of the water. The application of  a water softener removes these minerals from the water you use. These can be removed by boiling the water also.

There are other minerals, such as magnesium sulphate and calcium sulphate that make the water permanently hard. You’ll know your water is permanently hard when these minerals are not removed from the water by boiling. Just like the temporary hardness, it can also be removed by using water softeners.

Health benefits of hard water

Even very hard water is not harmful to health. The minerals in hard water, such as calcium and magnesium are beneficial to health. Hard water sometimes receive a bad rap. However, consider these benefits:

  • The mineral content in hard water supplement your daily dietary needs.
  • Hard water is better tasting than soft water.
  • Minerals in hard water reduce the solubility of some toxic metal ions such as lead and copper.
  • Pipe corrosion occurs more in areas that receives soft water.
  • Toxic metals such as cadmium and lead are easily dissolved by soft water.

Hard water solution

The main solution recommended for hard water is to use a water softener. Ion exchange is the process that is employed when using water softeners. This means that calcium and magnesium are replaced by sodium. Water softener is slightly more expensive than water conditioner, but it also provides the advantage of treating small amounts of other metals found in hard water, including zinc, iron or copper. Water softening unit uses sodium chloride or common table salt to change the mineral ions into sodium ions.

The Artistry Evolved From Primitive Age

The history of Geology is as ancient as the life on Earth, but it has been a matter of interest to humans only back in the 4th century. It was after Aristotle observed the evolution of rocks and minerals, the scientists and philosophers started to learn and mine certain crust around the 5th century. Geology, as a separate branch of science, was developed in the late 17th century. The geologists from various academies started to investigate every layer of earth and stop at every stone to find the fossils embedded within the Earth.

Rock Art is the term used by a number of historians over years. They are images embossed, carved or furrowed on a rock surface and are used to convey messages before writing has originated. They are simply the markings on a natural stone, according to archaeology, and this “rock art” is divided into the sub-disciplines in the late 19th century, like petroglyphs and pictographs. Petroglyphs are the carvings reflecting the Stone Age, while Pictographs are drawing or paintings on rocks.

seamounts-gravityDeriving from pre-historic times, these stone pecking is created by the ancestors of Pueblo people who lived in the Rhio Grande valley before A.D.500. These powerful cultural symbols reflect the tribal society and their ceremonies. Each carving relates to a known or unknown context which is extremely important, orienting the sphere or scenery. Some petroglyphs have meanings that are known only to its master while others are contemporary designs of religious existence, sceneries or any area and are honoured for its origin.

A pictograph, by the name itself, expresses the prehistoric abstracts in paintings or images on a rock. They are carefully arranged to convey messages, for example, paintings of animal hunting or wild animals of that era. These served as the pioneer for information about the ancient civilization and their habituates. The art forms are engraved in almost every cave that can be interpreted as the primitive symbols of hunting.

A Peep Into Nature’s Precious Creations

Mineraloids are not true minerals as they lack crystalline structures. They do not have a perfect formula and are inorganic naturally forming solid without the cleavage property. Abmer, Jet, Obsidian, Pearl and Pumice are some of the good examples of mineraloids. They are formed after the rapid solidification from a melt, where the constituents fail to develop an ordered atomic structure. They are formed by volcanic traits, Obsidian, for example is a randomly formed network of volcanic glass.

Mineraloids can be even from the galaxy of stars. Tektites and Moldavites are some among the outer space materials to the earth formed as a result of an asteroid or comet. They collide with Earth at very high velocity generating a large mass of energy. The explosion melts the rock into a stream of molten material, extending the molten to wide landscapes. As the temperature falls, it solidifies quickly and gives out amorphous pieces.

The Libyan Desert glass is believed to be yellow, is originated from a desert environment due to the lighting. Enormous spaces of deserts were flash melted with lightning strikes and they rapidly congeal as amorphous silica producing glassy textures. The Moldavites are also from the flash-heat phenomena and are found in the Eastern Europe. They amuse the geo-travellers and collectors with its beautiful green colour, and the clear stones can be modified as a gem.

opal_from_yowah_queensland_australia_2-300x200Organic mineraloids like Amber, found on sedimentary rock clusters, is actually the fossil plant resin. Another gem is the Jet, which is the rare black coal has a polished bright texture and are often cut into gemstones. The geologists are still searching for the evidence for Radiolarians and diatoms to be considered under mineraloids or not. The teeny-weeny creatures having thin amorphous shells sinks under the grounds cumulates to form sediments called ooze which eventually results in these organic solids.

Mineraloid environments are created beneath the earth’s surface where temperature and pressure are low. Materials like chrysocolla, limonite and opal freeze from gels and moulds to form minerals at favourable heat and temperature zones in the long run. Water and Mercury are also categorised as a natural inorganic substance which on modification changes to water ice and supercooled mercury.

Fossil Hunting at England’s Beaches

The fossils have been a fantasy for almost every one of us at some ages of our lives. The Hollywood movies and the animations tremendously influenced many of us to seek more about the origin and identity of fossils. The fossils of Dinosaurs may be the first thing that arises in our minds when we hear of fossils. But it’s a truth that outside the walls of a museum or university, there is astounding collection of these remains at the beaches or coasts of England.
kids-fossil-collecting2-300x200Before the journey to fossils, it is advisable to have a journal research regarding the places to visit. The Fossil masses can be seen at the England beaches like the Jurassic Coast in East Devon and Dorset, the Isle of Wight and the east Coast of Yorkshire. The Charmouth at Dorset has cliffs of Jurassic ocean floors where life existed over 200million years ago. When the cliffs crashed into the sea, the waves swept them away leaving behind the fossils on to the shores. There are also skeletons of giant reptiles and other endangered species. The skeleton of Scelidosaurus, the herbivorous species among dinosaurs, was discovered in December 2000. They inhabit the tropical islands around Charmouth.
The favourable time for fossil search is from April through November. Winter keeps the sea rough, giving a more clear vision of fossils. The dangerous tides can be a challenge and safety measures are to be followed.

A Little More About Mohs Hardness Scale

In earlier days, many geologists compared the hardness of a mineral by seeing which mineral can scratch others visibly and this lacks precision and accuracy. Hence, The Mohs scale was invented to measure the scratch resisting property of various minerals. Introduced by the German mineralogist, Friedrich Mohs in 1812, it measures the ability of one natural mineral to scrape another visibly.

Many minerals of pure and hard in nature were sampled and it was found that diamonds are the hardest naturally occurring mineral known so far. Scratching a mineral to measure on the scale creates non-elastic disorders visible to the naked eye. Minerals that are on the lower side of Mohs scale produce these distortions on materials and they have a higher Mohs number. If both the samples are of equal hardness, they will be no effect for the scrape, or might be difficult to determine the scratch.

mohs_hardness_testerThe procedure is as simple as it states. During the test, place the specimen to detect hardness on the table and hold it tightly in one hand. The reference specimen is kept against the unmarked surface of the sample. With a force, press the reference against the sample and give it a short drag move. Avoid injuries with sharp edges by placing away from your body. Check the blemish if they produced after dusting the residue of mineral powder. Use a hardness pick to get enhance accuracy. They are sharp metal picks, used to create a scrape easily if they are harder than the specimen being tested or leave a mere streak of metal if they are softer.

Hardness test is done as a mode of mineral identification easily when sophisticated techniques are unavailable. The suitability of the material to be used is determined in industries during the manufacture of products. It also helps to confirm that the materials that undergo wear and tear during the manufacturing withstand the pressure.

A Dive Into The Science Of Pyrotechnics

Ever wondered the science behind those glow in the dark effects? Pyrotechnics are nothing but the art of creating the firework display. The Chinese invented fireworks around 960AD which are now the part and prestige of every celebration across the world. The gears behind the brilliant colours and designs are a fusion of chemistry, physics and mathematics. People all over the world enjoy the tremendous booms of crackers, however, for science, these are the mass of powerful chemicals and fuels mounted together and calibrated to produce specific designs and colours.

The aerial magic of colours in the sky is the result of the explosion of a firework shell, with packed stars that are propelled to the air. The shell consists of gunpowder which is a mixture of charcoal, sulphur and potassium, in a paper tube with fuse installed to spark the tube. The outer cylinder is made of plastic or metal, where the gunpowder is filled with bottom of stars. The stars, in different shapes like cubes, spheres, cylindrical are nothing but the compounds that create colour and effects. The multiple fuses which ignite upon charge control the delay in time of the explosion.

300px-pyrotechnicsThe chemical makeup has a specific recipe for each colour with the deliberate addition of metallic compounds during the manufacture of stars. The pre-defined sculpting and mixing of stars emits specific colours and explodes to the sky with vibrant colours. The intensity of burst charge, the strength of the shell and the size of the stars is the foundation for the width of the display.

The elements like calcium emit less energy and correspond to the brilliant orange with a longer wavelength. The mixture of Strontium and copper with its oxides and carbonates has violet hues, which is the most difficult one to create. Barium compounds have green shades while crimsons and corals from Lithium compounds. Technological advancements made it possible to create multiple hues canvas capturing millions to the show.
