Weathering and Erosion

Front

What is weathering?

Back

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

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.

What is an example of erosion caused by water?

Back

Muddy water being carried away by a fast-moving river is an example of erosion.

What is an example of weathering caused by water?

Back

Flood water pounding on a canyon wall and wearing it down is an example of weathering.

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 natural force can cause erosion by moving sand?

Back

Wind can cause erosion by blowing sand from one place to another.

Front

What is an example of weathering caused by temperature changes?

Back

Freeze-thaw cycles, where water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart, is an example of weathering.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often transported by water, wind, or ice.

Front

What role do rivers play in erosion?

Back

Rivers can erode the land by carrying away soil and rocks as they flow, shaping the landscape over time.

Front

What is an example of erosion caused by ocean waves?

Back

Ocean waves moving sand back and forth on a beach is an example of erosion.
