Ch. 7 Erosion and Deposition Test

Water erosion begins when runoff from rainfall flows in a thin layer over the land in a kind of erosion called

• mass erosion

• sheet erosion

• creep

• gully erosion

The process by which natural forces move weathered rock and soil from one place to another is called

• soil conservation

• deposition

• erosion

• abrasion

Landslides, mudflows, slump, and creep are all examples of

• mechanical weathering

• runoff

• mass movement

• soil formation

Deltas are built up by

• deposition

• leaching

• abrasion

• erosion

The process in which rock fragments freeze to the bottom of a glacier and then are carried away when the glacier moves is called

• plucking

• surging

• valley widening

• abrasion

The energy that produces ocean waves comes from

• the rise and fall of the tides

• rivers flowing into the ocean

• wind blowing across the water’s surface

• rock falling into the ocean along the shore

A wide sloping deposit of sediment formed where a stream leaves a mountain range is called a(n) __________.

• divide

• drainage basin

• alluvial fan

• slump

The process by which wind removes surface materials is called __________.

• abrasion

• plucking

• deflation

• inflation

Which of the following is evidence that an area was once covered by a glacier?

• loess deposits

• V-shaped valley

• U-shaped valley

• alluvial fan

What is one main difference between continental glaciers and valley glaciers?

• Continental glaciers are much larger and thicker.

• The type of glacier is made of different materials.

• Valley glaciers cause more erosion.

• Continental glaciers never melt.
