Weathering and Erosion

Front

What is the process called when rocks and minerals are broken down into smaller pieces by natural forces such as water, wind, and temperature changes?

Back

Weathering

Front

What is the term for the movement of sediment from one location to another by natural forces like water and wind?

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 the two main types of weathering?

Back

Physical weathering and chemical weathering.

Front

What is physical weathering?

Back

The mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, altering their mineral composition.

Front

What role do living organisms play in weathering?

Back

Living organisms can contribute to weathering through processes like root expansion and organic acid production.

Front

How does temperature change contribute to weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to cracks and eventual breakdown.
