Weathering and Erosion Flashcard

Front

What is mechanical weathering?

Back

The process of breaking down rocks into smaller pieces without changing their chemical composition, such as freezing water breaking rocks apart.

Front

What is chemical weathering?

Back

The process that alters the minerals in rocks through chemical reactions, often involving water, acids, and gases.

Front

What is erosion?

Back

The movement of weathered rock pieces from one location to another by natural forces such as wind or water.

Front

What are sediments?

Back

Small pieces of rock and minerals that are formed by the weathering of larger rocks.

Front

What is water management?

Back

The planning and use of water resources to ensure sustainable supply and quality.

Front

What role does carbon dioxide play in weathering?

Back

Carbon dioxide can combine with water to form carbonic acid, which contributes to chemical weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What are some examples of mechanical weathering?

Back

Freezing and thawing cycles, abrasion by wind or water, and root expansion from plants.

Front

What are some agents of erosion?

Back

Water, wind, ice, and gravity are all agents that can cause erosion.

Front

How does acid rain affect weathering?

Back

Acid rain can accelerate chemical weathering by reacting with minerals in rocks.
