Changes in the Geosphere 1

Front

What is erosion?

Back

Erosion is the movement of soil and rock by wind, water, ice, and gravity.

Front

What are the main causes of erosion?

Back

The main causes of erosion are wind and water.

Front

What is deposition?

Back

Deposition is the process where materials are dropped or settled after being transported by erosion.

Front

How does the slope of a hill affect erosion?

Back

A steeper slope can lead to more erosion because water flows faster down the hill.

Front

What is a fair test in an experiment?

Back

A fair test is when only one variable is changed at a time while keeping all other conditions the same.

Front

What role does soil type play in erosion?

Back

Different types of soil can erode at different rates; for example, sandy soil may erode faster than clay soil.

Front

What happens to erosion when a river runs quickly?

Back

When a river runs quickly, there is usually more erosion because the fast-moving water can carry away more soil and rocks.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and soil, while erosion is the movement of those materials.

Front

What is an example of a change agent that forms deltas?

Back

Deposition is the change agent responsible for forming deltas, where sediment is deposited at the mouth of a river.

Front

What is the effect of ice on erosion?

Back

Ice can cause erosion through processes like glacial movement, which can scrape and carry away large amounts of soil and rock.
