Rocks and Rock Cycle

Front

What is compaction in the context of rocks?

Back

Compaction is the process that occurs when rocks are deeply buried and placed under pressure due to the weight of overlying layers, leading to a reduction in volume.

Front

True or False: A rock consists of two or more minerals.

Back

True

Front

How many ways can igneous rock transform into sedimentary rock according to the rock cycle?

Back

One way.

Front

True or False: Igneous rock becomes Metamorphic by melting and cooling.

Back

False. Igneous rock becomes Metamorphic through heat and pressure, not melting and cooling.

Front

What is the Rock Cycle?

Back

The Rock Cycle is a model that describes the formation, breakdown, and reformation of rocks.

Front

What is lithification?

Back

Lithification is the process of turning sediments into solid rock through compaction and cementation.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed from the accumulation and consolidation of mineral and organic particles.

Front

What is the role of weathering in the rock cycle?

Back

Weathering is the process that breaks down rocks into smaller particles, which can then be transported and deposited.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, or chemically active fluids.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from the cooling and solidification of magma or lava, while sedimentary rocks form from the accumulation of sediments.
