Igneous rock sedimentary rock and metamorphic rock.
Is granite igneous metamorphic or sedimentary.
Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.
Then due to various conditions within the earth the existing rock was changed into a.
The granite melts into lava then cools becoming igneous.
Each kind of igneous rocks contains different minerals and has different structures.
Igneous rocks comprise about 95 of the total earth s crust.
A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.
These molten substances are called magma or lava magma can be derived from melting of existing rocks on the earth crust.
The sedimentary rock becomes metamorphic with heat and pressure.
It erodes into sediment and then gets compressed into a sedimentary rock.
There are many types of igneous rocks.
Most of the solid surface of our planet ro ughly 70 is represented by sedimentary rocks but if you go deep enough beneath the earth s surface there are plenty of igneous and metamorphic r.
Igneous rocks are formed when molten substances below the earth surface cools down and solidifies.
Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened.
The existing rock type which undergoes a change is referred to as the protolith.
Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust.
We have 3 main types or classes of rock based on how they are formed.
Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage.
