LWH Erosion & Deposition Practice

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is deposition?

Back

Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the amount of erosion that occurs on slopes.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river, where it meets a body of water, and sediment is deposited.

Front

What role does water flow speed play in erosion?

Back

Faster water flow increases the ability of water to erode sediment, while slower water flow tends to deposit sediment.

Front

What is runoff?

Back

Runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flow over the ground.

Front

What is a meander?

Back

A meander is a winding curve or bend in a river or stream, often formed by the erosion of the outer bank and deposition on the inner bank.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals at the Earth's surface, while erosion involves the movement of those materials.

Front

What factors contribute to increased erosion on slopes?

Back

Factors include steepness of the slope, lack of vegetation, and heavy rainfall.

Front

What is the significance of sediment size in deposition?

Back

Larger particles are typically deposited first as water slows down, followed by smaller particles.
