Weathering, Erosion, and Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the laying down or settling of eroded material in a new location.

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 abrasion in the context of weathering?

Back

Abrasion is the process of scraping or wearing away of rock surfaces due to friction and impact from particles carried by wind, water, or ice.

Front

What role do glaciers play in erosion?

Back

Glaciers can erode rock and soil as they move, transporting the material to new locations.

Front

What is hydrolysis in chemical weathering?

Back

Hydrolysis is a chemical weathering process where water reacts with minerals to form new minerals and soluble salts.

Front

What is oxidation in chemical weathering?

Back

Oxidation is a chemical reaction where oxygen reacts with minerals, often leading to rusting in iron-rich rocks.

Front

What is carbonation in chemical weathering?

Back

Carbonation is a process where carbon dioxide dissolves in water, forming carbonic acid, which can dissolve certain minerals.
