4th Grade Weathering, Erosion, and Deposition

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one place to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

How does ice cause weathering?

Back

Ice can cause weathering by freezing in the cracks of rocks, expanding, and breaking the rocks apart.

Front

What role does water play in erosion?

Back

Water can carry away soil and rocks, reshaping landscapes as it flows over them.

Front

What is the effect of wind on rocks?

Back

Wind can erode rocks by carrying sand and small particles that scrape against the rock surfaces.

Front

How do waves contribute to erosion?

Back

Waves from the ocean can erode cliffs and shorelines by crashing against them and carrying away materials.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces to a new location.

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops off sand and gravel, forming a delta.

Front

How do plants affect weathering?

Back

Plants can cause weathering by growing roots that break apart rocks as they expand.
