Rocks, Minerals and Weathering Review

Front

What is erosion?

Back

Erosion is the process of moving away sediments at the Earth's surface, primarily caused by agents such as water, wind, glaciers, and mass wasting (gravity).

Front

What is magma?

Back

Magma is molten rock that is formed by the melting of rocks beneath the Earth's surface.

Front

What is an intrusive igneous rock?

Back

An intrusive igneous rock is formed by the cooling and solidification of magma beneath the Earth's surface.

Front

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

Back

True.

Front

What is compaction in geology?

Back

Compaction is the process that occurs when rocks are deeply buried, placing them under pressure due to the weight of overlying layers.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks at the Earth's surface through physical, chemical, or biological means.

Front

What is sediment?

Back

Sediment refers to small particles of rock, minerals, and organic material that are transported and deposited by wind, water, or ice.

Front

What is lithification?

Back

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

Front

What is the difference between sedimentary and igneous rocks?

Back

Sedimentary rocks are formed from the accumulation of sediments, while igneous rocks are formed from the cooling and solidification of magma or lava.

Front

What is the role of gravity in erosion?

Back

Gravity contributes to erosion by causing mass wasting, where materials move down slopes due to gravitational pull.
