Metamorphic Rocks are formed deep beneath the earth's surface, when pressure and heat are applied to a sedimentary or igneous rock- making a major change to the structure. Below is an example of a metamorphic rock called slate.
Metamorphosis can be defined as "changing form", and that's why these rocks are called metamorphic rocks. The changes that happen to the rocks only happen under a lot of pressure. That is why these rocks are the most rare out of the three kinds. Even though they are rare we can still recognize some of these rocks as things that we have seen before in our own lives.
Limestone, a sedimentary rock, can be seen all around Indiana University Bloomington's campus making up the outside of most of their buildings. This sedimentary rock turns into the metamorphic rock we call marble.High heat and pressure cause the calcite in the limestone to recrystallize into larger crystal structures that make up the marble.We can see this in kitchen's and fancy floors all the time. So even though the rocks are rare and hard to come by, they are all around us everyday. Below are some more metamorphic rocks you may recognize.
The post below also shows how all three rock types are related and created! It's a great visual to look at it get a better understanding!
And for more fun... If you want to learn more about metamorphic rocks, igneous, or sedimentary you can go to the link below and listen to fun song about the rock family!
