U4L1 Weathering and Erosion pgs163-172

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

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

Front

What is sediment?

Back

Sediment is small pieces of rock, soil, and other materials that are carried and deposited by water, wind, or ice.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where sediment is deposited as the river flows into a larger body of water.

Front

What causes canyons to form?

Back

Canyons are formed by the erosion of rock and soil by flowing water over a long period of time.

Front

What role does flowing water play in erosion?

Back

Flowing water has energy that can erode rocks and soil, transporting sediment downstream.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces from one location to another.

Front

How can wind cause weathering?

Back

Wind can cause weathering by carrying small particles that hit rocks, breaking them apart over time.

Front

What is chemical weathering?

Back

Chemical weathering is the process where rocks undergo chemical changes, often due to reactions with water or acids, leading to their breakdown.

Front

What is the effect of rain on rocks?

Back

Rain can cause weathering by wearing down rocks and can also lead to erosion by carrying away the weathered materials.
