Regional Metamorphism Concepts

Riley AE discusses regional metamorphism, a process where rocks undergo changes due to heat, pressure, and fluid movement. The video covers different types of metamorphism, focusing on regional metamorphism, which occurs over large areas and is common in mountain ranges like the Himalayas. Examples of rocks formed through this process include slate and marble. The video concludes with a summary and sources.

What is metamorphism primarily associated with?

• Changes in rock location

• Changes in heat, pressure, or fluid movement
