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 the speed of water affect erosion?

Back

Faster-moving water has more energy and can carry larger particles, leading to increased erosion.

Front

What is the relationship between weathering and erosion?

Back

Weathering breaks down rocks into smaller particles, which can then be transported by erosion.

Front

What factors influence the rate of erosion?

Back

Factors include the type of soil, vegetation cover, slope of the land, and the speed of water flow.

Front

What is a meander in a stream?

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

Why does erosion lead to deposition?

Back

Erosion leads to deposition because the erosion agent (like water) slows down, causing the sediments to settle.

Front

What type of slope is most susceptible to erosion?

Back

A steep, bare slope is most susceptible to erosion due to runoff.

Front

What is undercutting in the context of erosion?

Back

Undercutting occurs when water erodes the base of a slope or cliff, leading to instability and potential collapse.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the likelihood of erosion by water or wind.
