Metamorphic Rocks 3.4 - Coggle Diagram
Metamorphic Rocks 3.4
Vocabulary
Contact metamorphism
When magma intrudes—forces it’s way into—rock , contact metamorphism
-
-
Hydrothermal solutions
When these hot, water-based solutions escape from a mass of magma, they are called hydrothermal solutions
Regional Metamorphism
During mountain building, large areas of rocks are subjected to extreme pressures and tempatures
Pressure
Pressure, like temperatures, also increases with depth
-
Key concept
Most metamorphic changes occur at elevated tempatures and pressures. These conditions are found a few kilometers below earths surface and extend into the upper mantle
Key concept
The agents of metamorphism are heat, pressure, and hydrothermal solutions
-
Key concept
During contact metamorphism, hot magma moves into rock
