Rocks are cool!

To learn all of the types of rocks can take a quite a bit of time. There are three types of rock categories igneous, sedimentary, and metamorphic. I know to most of you a rock is just a rock. But to geologist rocks are more than just rocks. Rocks are extremely important to our society. The reason why rocks are important to society is because of what they can tell us. Rocks can be carbon dated to see how old they actually. By knowing the age of the rocks geologist can see how the climate was back then, and then they can estimate how old it is on the geologic time scale. For some of the types of rocks out there. For rocks like shale, sandstone, and rock salt just to name a few of them. To give you a few example of igneous rocks you have basalt, granite, and pumice to name a few. For metamorphic rocks you have gneiss, marble, and slate just to name a few. Now I’m sure that some of you have granite counter tops. The granite counter tops are extremely nice. Marble and slate are used for counter tops sometimes depending on the application they’re being used. Marble and slate are used in for tile flooring as well. All these types of rocks are used in so many important applications. I just provided a few examples of some of the igneous and metamorphic rock applications. These are the reasons why rocks are so has always been so vital to our society. To go off on a limb here my favorite type of sedimentary rock is limestone. My favorite type of igneous rock is granite. And for my favorite metamorphic rock is marble. To find out more information about all these rocks and what applications they are used in.
