Weathering, Erosion, & Deposition Review Flashcardizz

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 relocation (or movement) of sediment by wind, water, gravity, or ice.

Front

What is deposition?

Back

The process by which sediment settles out of the transporting medium, such as water or wind.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical changes, altering their mineral composition.

Front

Give an example of mechanical weathering.

Back

Ice wedging, where water seeps into cracks, freezes, and expands, breaking the rock apart.

Front

Give an example of chemical weathering.

Back

The reaction of carbon dioxide with water to form carbonic acid, which can dissolve limestone.

Front

What role do plants play in weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing mechanical weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion involves the movement of those broken pieces.

Front

What is the impact of gravity on erosion?

Back

Gravity can cause rocks and soil to move downhill, leading to erosion.
