UNIT 4: Weathering/Erosion/Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

Erosion is the process by which rock and soil are moved from one place to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often occurring at the mouth of a river.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to their breakdown.

Front

What is oxidation in terms of weathering?

Back

Oxidation is a type of chemical weathering where a substance combines with oxygen, such as iron rusting.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion carries the broken pieces away.

Front

What role does water play in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away particles and shaping the landscape.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river where it meets a larger body of water.

Front

What is the impact of vegetation on erosion?

Back

Vegetation helps to reduce erosion by stabilizing soil with roots and absorbing water.
