Weathering, Erosion, & Deposition

Front

What is Weathering?

Back

Weathering is the process that breaks down rocks and minerals 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 process where materials transported by wind, water, or ice are dropped or settled in a new location.

Front

How do sand dunes form?

Back

Sand dunes form when wind stops blowing and deposits sand in a new location.

Front

What role does water play in weathering?

Back

Water can cause weathering by pounding against rocks, leading to their breakdown.

Front

What is an example of biological weathering?

Back

An example of biological weathering is when plant roots grow in cracks of rocks and cause them to split.

Front

How does wind contribute to erosion?

Back

Wind contributes to erosion by blowing sand and other particles from one location to another.

Front

What happens during the process of deposition?

Back

During deposition, materials like sand or silt are dropped when the transporting medium (like wind or water) slows down.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a new location.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the freezing and thawing of water in rock cracks, causing the rocks to break apart.
