What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed by heat, pressure, and chemically active fluids.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through geological processes.

Front

What is the significance of mineral hardness in identification?

Back

Mineral hardness, measured by the Mohs scale, helps identify minerals based on their resistance to scratching.

Front

What is a mineral?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and crystalline structure.

Front
