Front

What is the process by which igneous rocks are formed?

Front

Front

Define sedimentary rock.

Back

Rocks formed from the accumulation and compaction of mineral and organic particles.

Front

What is metamorphism?

Back

The process by which existing rocks are changed into new types of rocks due to heat, pressure, or chemically active fluids.

Front

What is the rock cycle?

Back

The continuous process by which rocks are formed, broken down, and reformed over time.

Front

What is weathering?

Back

The breaking down of rocks into smaller pieces by natural processes such as wind, water, and temperature changes.
