What happens to a rock when heat
and pressure are applied?
The rock could change both it’s
shape and it’s composition.
What is a metamorphic rock when it is
“nonfoliated”?
The minerals in these rocks organized randomly.
What is metamorphic rock?
Rock formed from another rock because of heat and pressure.
What does pockets of magma do?
Pockets of magma can rise
through the crust.
How do geologists classify metamorphic
rock?
Geologists classify rocks according to the
arrangement of the grains making up the rocks.
