Weathering | Erosion | Deposition

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What is erosion?

Back

The process by which weathered rock and soil are moved from one location to another by wind, water, or ice.

Front

What is deposition?

Back

The process where sediments, soil, and rocks are added to a landform or land mass.

Front

What is physical weathering?

Back

The breakdown of rocks into smaller pieces without changing their chemical composition, often caused by temperature changes, freeze-thaw cycles, or abrasion.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and substances like acids.

Front

Give an example of erosion.

Back

Wind blowing away sediment from a beach.

Front

What is the main difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What role does water play in weathering?

Back

Water can cause both physical weathering (through freeze-thaw cycles) and chemical weathering (by dissolving minerals).

Front

What is an example of chemical weathering?

Back

Acid rain wearing away limestone.

Front

How does vegetation affect erosion?

Back

Vegetation helps to anchor soil in place, reducing the likelihood of erosion.
