HOW DO ROCKS FORM AND WHAT CAN THEY TELL US? - The rock cycle

In this video you will learn that rocks can be formed  in three different ways, and correspondingly there are three different types of rocks: magmatic rocks, sedimentary rocks and metamorphic rocks. You will also learn that rocks are continuously transformed from one type to another in a set of processes know as the rock cycle. Finally, we will also see how, by observing the rocks, we can learn a lot about the environment where they were formed, about the past of our planet, and so much more ....
