Weathering, erosion, and deposition review

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What is deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

What is the A horizon in soil?

Back

The top layer of soil, also known as topsoil, which is rich in organic material and nutrients.

Front

What is the B horizon in soil?

Back

The layer of soil beneath the A horizon, also known as subsoil, which contains minerals leached from the upper layers.

Front

What is the C horizon in soil?

Back

The layer of soil composed of partially weathered rock and mineral material, serving as the parent material for the upper layers.

Front

What is the D horizon in soil?

Back

The bedrock layer beneath the soil horizons, which has not been significantly altered by weathering.

Front

What happens to sediment when wave action is quiet?

Back

Sediment is deposited when wave action is quiet and water is moving more slowly.

Front

What is a dissolved load in a stream?

Back

Particles carried by the stream in solution, typically consisting of minerals and organic matter.

Front

What are ventifacts?

Back

Stones that have become polished and faceted due to abrasion by wind-blown sands.
