Weathering, Erosion, Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is physical weathering?

Back

The breaking down of rocks into smaller pieces without changing their chemical composition, often due to 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, acids, or gases, leading to changes in mineral composition.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering; it can freeze and expand in cracks (physical) or react with minerals to form new substances (chemical).

Front

What is an example of erosion caused by wind?

Back

Desert sand dunes are formed by the erosion of sand particles carried by the wind.

Front

What is an example of deposition?

Back

The formation of deltas at river mouths where sediment is deposited as the river slows down.

Front

What is the impact of acid rain on limestone?

Back

Acid rain causes chemical weathering of limestone, leading to the dissolution of calcium carbonate and the formation of features like sinkholes.

Front

What are the main agents of erosion?

Back

Wind, water, and ice are the primary agents that cause erosion by transporting weathered materials.
