4th grade Weathering, Erosion, Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like water, ice, and wind.

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where sediments are dropped off in a new location after being transported by erosion.

Front

What are the main agents of weathering?

Back

The main agents of weathering include water, ice, wind, and temperature changes.

Front

How does water cause weathering?

Back

Water can cause weathering by freezing and thawing, which expands and contracts rocks, leading to cracks.

Front

What role does ice play in weathering?

Back

Ice can cause weathering by expanding in cracks of rocks when it freezes, breaking the rocks apart.

Front

What is the difference between weathering and erosion?

Back

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

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediments at the mouth of a river where it meets a body of water.

Front

What is a U-shaped valley?

Back

A U-shaped valley is formed by the erosion of glaciers, which carve out the landscape as they move.

Front

What is the process of compaction?

Back

Compaction is the process where sediments are pressed together under pressure, often leading to the formation of sedimentary rocks.
