Understanding Weathering Processes

Front

What is weathering?

Back

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

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical (mechanical) weathering and chemical weathering.

Front

Define physical weathering.

Back

Physical weathering is the process that breaks rocks into smaller pieces without changing their chemical composition.

Front

Define chemical weathering.

Back

Chemical weathering involves the alteration of the chemical composition of rocks, often through reactions with water, acids, or gases.

Front

What is dissolution in the context of weathering?

Back

Dissolution is a chemical weathering process where minerals dissolve in water, often leading to the formation of features like caves.

Front

What role does water play in weathering?

Back

Water is a key agent in both physical and chemical weathering, facilitating processes like dissolution and freeze-thaw cycles.

Front

What is glacier abrasion?

Back

Glacier abrasion is a process where glaciers scrape and erode the underlying rock surface as they move.

Front

What is wind abrasion?

Back

Wind abrasion is a type of physical weathering where wind carries sand and other particles that wear away rock surfaces.

Front

How do plant roots contribute to weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing physical weathering.

Front

What is exfoliation?

Back

Exfoliation is a physical weathering process where layers of rock peel away due to temperature changes.
