Unit 4 Review

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface, formed by the melting of rocks due to high temperature and pressure.

Front

What is lava?

Back

Lava is molten rock that has erupted onto the Earth's surface from a volcano.

Front

What is deposition in geology?

Back

Deposition is the process by which sediments are added to a landform or land mass, often occurring in bodies of water.

Front

What is compaction?

Back

Compaction is the process where layers of sediment build up and exert pressure on the layers below, causing them to become denser.

Front

What is weathering?

Back

Weathering is the breakdown of rocks and minerals due to environmental factors like rain, wind, ice, sunlight, and biological activity.

Front

What is erosion?

Back

Erosion is the process of transporting rock fragments and sediments by natural forces such as water, wind, ice, or gravity.

Front

What is lithification?

Back

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

Front

What are sediments?

Back

Sediments are small particles of rock, minerals, or organic material that are transported and deposited by natural processes.

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 difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one location to another.
