Weathering & Erosion

Front

What is weathering?

Back

The breaking down of Earth’s crust into smaller and smaller pieces.

Front

Which type of climate will have faster chemical weathering?

Back

Hot and Wet

Front

What is erosion?

Back

The process by which water, ice, wind, or gravity moves fragments of rock and soil.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and acids.

Front

Which of the following is NOT a type of chemical weathering?

Back

Ice wedging.

Front

What role does carbonic acid play in weathering?

Back

Carbonic acid in rainwater can dissolve minerals in rocks, leading to weathering.

Front

How does temperature affect weathering?

Back

Higher temperatures can increase the rate of chemical reactions, leading to faster weathering.

Front

What is mechanical weathering?

Back

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

Front

Give an example of mechanical weathering.

Back

Frost wedging, where water freezes in cracks of rocks and expands, causing the rock to break.

Front

What is the impact of living organisms on weathering?

Back

Living organisms, such as lichens, can secrete acids that contribute to chemical weathering.
