Chapter 2.1 Weathering/Erosion Study Guide

Front

What is mass wasting?

Back

The downhill movement of loose rocks and soil caused by gravity.

Front

What is mechanical weathering?

Back

The breaking down of rocks by physical processes without changing their chemical composition.

Front

What do landslides, mudflows, and soil creep have in common?

Back

They all involve soil moving downhill.

Front

What are deflation hollows?

Back

Soil depressions scooped out by wind.

Front

Is climate a major factor of mechanical weathering in a desert?

Back

False, because there is so little water.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What are some examples of mechanical weathering?

Back

Frost wedging, thermal expansion, and abrasion.
