Erosion & Deposition

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

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

Deltas are built up by

• deposition

• leaching

• abrasion

• erosion

A river flowing across a wide flood plain begins to form looplike bends called

• rills

• meanders

• outside curves

• deltas

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

• mechanical weathering

• runoff

• mass movement

• soil formation

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

• soil conservation

• deposition

• abrasion

• erosion

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

• gullying

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

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

• divide

• drainage basin

• alluvial fan

• slump
