Metamorphic Rock
Metamorphic rock is the result of the (chemical or physical) properties of
sedimentary, igneous, or previously modified metamorphic rock being
changed either by great pressure or heat. At the core of the earth, there
is a very hot substance called magma, under great pressure. The
outside of this roughly spherical area is where the metamorphic rock is. Below
is a diagram of this phenomenon and another shows the rock cycle. Can you tell what kind of igneous
rock each pattern demonstrates? (the first image)
