Weathering, Erosion, & Deposition Flashcard

Front

What is weathering?

Back

Weathering is the breaking down of rocks into smaller pieces called sediments.

Front

What is erosion?

Back

Erosion is the process of moving sediments from one place to another.

Front

What is deposition?

Back

Deposition is the dropping off of sediments, which can lead to the formation of new landforms.

Front

How do river currents affect rocks?

Back

River currents cause rocks to bump and scrape against one another, making them smaller.

Front

What causes erosion from water?

Back

Erosion from water occurs when flowing water carries away sediments and shapes the land.

Front

What is an example of deposition?

Back

An example of deposition is when a river drops off sand at its mouth, forming a delta.

Front

What role does wind play in erosion?

Back

Wind can erode surfaces by carrying away loose particles and sediments.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away.

Front

What can cause weathering?

Back

Weathering can be caused by natural elements like rain, ice, and temperature changes.

Front

What happens to rocks during physical weathering?

Back

During physical weathering, rocks break into smaller pieces without changing their chemical composition.
