Erosion

Front

What is erosion?

Back

Erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust and transports it to another location where it is deposited.

Front

What are the main agents of erosion?

Back

The main agents of erosion include water, wind, ice, and gravity.

Front

How do glaciers contribute to erosion?

Back

Glaciers contribute to erosion by scraping and carving the land as they move, transporting debris and sediment.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the removal and transport of material, while weathering is the process of breaking down rocks and minerals without movement.

Front

What role does water play in erosion?

Back

Water can erode land through processes such as rainfall runoff, river flow, and ocean waves, leading to the removal of soil and rock.

Front

What is an example of erosion caused by wind?

Back

An example of erosion caused by wind is the formation of sand dunes in desert environments.

Front

What is the impact of vegetation on erosion?

Back

Vegetation helps to reduce erosion by stabilizing soil with roots and absorbing water, which decreases runoff.

Front

What is mass wasting?

Back

Mass wasting is the movement of soil and rock down a slope due to gravity, contributing to erosion.

Front

What is the significance of sediment deposition?

Back

Sediment deposition is significant as it creates new landforms, such as deltas and alluvial plains, and can affect ecosystems.

Front

What is oxidation, and why is it not considered erosion?

Back

Oxidation is a chemical process that alters minerals but does not involve the physical removal or transport of material, thus it is not considered erosion.
