Weathering, Erosion, and Deposition Flashcard

Front

What is the definition of deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or landmass.

Front

What is weathering?

Back

The breaking down of rocks into smaller pieces through physical, chemical, or biological processes.

Front

What is erosion?

Back

The movement of weathered materials by wind, water, ice, or gravity.

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 alters the chemical structure of rocks, often leading to the formation of new minerals.

Front

What is frost wedging?

Back

A type of mechanical weathering where water seeps into cracks, freezes, and expands, causing the rock to break apart.

Front

What are eskers?

Back

Long, winding ridges of sand and gravel deposited by meltwater from glaciers.

Front

What is the role of weathering in soil formation?

Back

Weathering breaks down rocks into smaller particles, which combine with organic material to form soil.

Front

What is oxidation in the context of weathering?

Back

A chemical weathering process where minerals react with oxygen, often leading to rusting in iron-rich rocks.

Front

What is deposition and compaction?

Back

The process by which sediments settle out of a transporting medium and are compressed to form sedimentary rocks.
