The Wonders Of A Geologic Map

By Betty Allen


When you are studying geology but are still learning some of the technical aspects of the field, a few things will help you make sense of it all. A solid geologic map, for example, will show you which rocks are visible in which locations within the United States and indeed the world. You can use these images for special projects that will uncover what happened in the past.

All maps that are used in geology will be properly color coded so that users can immediately spot what they are looking for. All Jurassic age rocks, for example, will be given the same color. If you are doing a project on a certain dinosaur that lived during the Jurassic, you'll want to explore rocks where fossils of these great beasts might actually be found.

Large maps are usually printed on paper that be rolled up and taken with you when you are on an expedition. Keep the paper casually rolled up and then use a rubber band to tie it off. When out in the wilderness, the rubber band can be taken off and the paper unsheathed and set up on a flat surface for everyone to examine. This should keep the material itself from tearing or degrading too fast.

You should always be able to find what you're looking for online. You can buy maps in bulk and then have then delivered to your house or university department within just a few days. University geology professors usually order several at once to get a better price overall. This saves the department money in the long run.

Taking a few classes on the side can help you learn a lot more about things like volcanoes. Volcanoes vary in how explosive they can be, and ones that are located near tectonic boundaries are likely to be more dangerous. Lava flows and other volcanic debris can be quite interesting to study once they have cooled.

Taking a class in how mountain belts form is also interesting. The Appalachians, for example, are an ancient mountain range that has worn down with time. Mountains usually form when plates collide with each other and rub up against each other. Some minerals are associated with different kinds of stresses and strains, and you can analyze in these field.

Any good geologist will delve deep into Earth's history to learn about how the planet actually formed. The commonly accepted theory is that the planets formed out of the collapse of the solar nebula, which occurred between four and five billion years ago. As the inner rocky planets gained mass, they fell into orbits around the sun, where they still exist today.

You will ultimately want to find a map that gives you every chance of meeting with success in your field. As long as you purchase a set that clearly marks geologic boundaries with different colors, you should succeed. With luck, you can keep the paper in great shape and continue to bring it out whenever you are going to be hiking through the woods and looking at rocks.
