What is metamorphism in geology?
Q: What is metamorphism in geology?
A: Metamorphism is the process of changing the structure, texture, or composition of rocks due to various factors.
Q: What is the scientific study of rocks known as?
A: The scientific study of rocks is called petrology.
Q: How are rocks classified according to their origin?
A: Rocks are classified according to their origin into three major classes – Igneous, sedimentary, and metamorphic.
Q: What are the factors responsible for causing metamorphism in rocks?
A: Factors responsible for causing metamorphism in rocks are heat, deforming pressure, shearing stress, hot/chemically active fluids, or a combination of these.
Q: What happens to the physical character of a rock mass when metamorphism occurs?
A: When metamorphism occurs, it changes the physical character of the rock mass while remaining essentially in the solid state.
Q: When are rocks formed according to the theory?
A: According to the theory, rocks are formed when the things surrounding them are in equilibrium with ambient physical conditions.
Q: What causes metamorphism to occur in rocks?
A: Movements in the earth's crust or igneous activity can change the conditions, causing metamorphism to occur to reestablish equilibrium and change the physical character of the rock mass.
