Answer:
What changes do metamorphic rocks undergo?
Metamorphism is the addition of heat and/or pressure to existing rocks, which causes them to change physically and/or chemically so that they become a new rock. Metamorphic rocks may change so much that they may not resemble the original rock.
Step-by-step explanation:
What are 2 main factors that cause metamorphism in rocks?
The main factors that control metamorphic processes are:
The mineral composition of the parent rock.
The temperature at which metamorphism takes place.
The amount and type of pressure during metamorphism.
The types of fluids (mostly water) that are present during metamorphism.
The amount of time available for metamorphism.What are the 5 processes that affect rocks over time?
Several processes can turn one type of rock into another type of rock. The key processes of the rock cycle are crystallization, erosion and sedimentation, and metamorphism.
