Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process when water, ice, and wind move particles of rock and soil from one place to another.

Front

What is ice wedging?

Back

Ice wedging is a type of weathering where water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces.

Front

What happens during erosion caused by flood waters?

Back

Flood waters can move soil from one location to another, which is an example of erosion.

Front

How does wind contribute to weathering?

Back

Wind can blast sand at rocks, causing them to wear away and even carve out caves, which is a form of weathering.

Front

What is sediment?

Back

Sediment refers to small particles of rock and soil that have been moved by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces from one place to another.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like ice wedging and chemical reactions.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process of rocks being worn down by friction and impact from other particles.

Front

What is the effect of acid rain on rocks?

Back

Acid rain can chemically weather rocks, breaking them down more quickly than normal rain.
