Metamorphic Rock
Heat and pressure can cause rocks to go through physical and chemical changes. When
this happens we call the rock metamorphic. Metamorphic rocks are rocks that have
changed due to heat and or pressure. This pressure can be from the weight of the rocks
above or the pressure of the two tectonic plates crashing into each other. The heat can
come from the pressure or come from magma that is rising up through the rock.
Pressure from the weight of the Earths crust
Metamorphic Rock
Heat from the Earth’s core

Answer:
2. Where can the pressure come from?
Answer:
3. Where can the heat come from?
Answer:
Two Types of Metamorphism
When metamorphic rocks are formed scientists call it metamorphism. Metamorphism is
the process in which one type of rock is turned into another because of chemical changes
from heat and pressure. There are two types of metamorphism. They are called contact
metamorphism and regional metamorphism. The difference between the two has to do
with what caused the rock to change.
1. What is metamorphism?
Answer:
2. What are the two types of metamorphism?
Answer:
Contact Metamorphism
When a relatively small amount of rock is changed due to heat from contact with magma.
This type of metamorphism happens just where the rocks come in contact with magma.
1. What is contact metamorphism?
Answer:
Regional Metamorphism
When a large area of rock is changed from pressure and heat due to the movement of
the Earth’s crust. This type of metamorphism happens over a very large region.
Regional Metamorphism
