Weathering, Erosion, Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces 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 of breaking down rocks without changing their chemical composition, often through temperature changes, freeze-thaw cycles, or abrasion.

Front

Define chemical weathering.

Back

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

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

How does weathering differ from erosion?

Back

Weathering is the breakdown of materials, while erosion is the movement of those materials from one place to another.

Front

What role does vegetation play in erosion?

Back

Vegetation helps to reduce erosion by stabilizing soil with roots and absorbing water, which decreases runoff.

Front

What is the impact of climate on weathering processes?

Back

Climate affects weathering processes; for example, chemical weathering is more prevalent in warm, wet climates, while physical weathering is more common in cold, dry climates.
