Erosion and Deposition

Which particle would have the slowest rate of deposition?

• Round particle

• very large particle

• particle with sharp ends

• particle with a high density

What role does weathering have in shaping Earth’s surface?

• It allows sediments to fall out of a medium.

• It helps sediments settle on a new surface.

• It breaks down older material into sediments

• It transports sediments to a different location.

A rocky hill cracks after water settles and freezes. Several trees on the hill tilt due to the very slow downhill movement of rock and soil. The movement occurs over a long distance.

Which type of mass movement does this describe?

• creep

• landslide

• mudflow

• slump

How does the substance in a mudflow form?

• Rain mixes with soil

• Large rocks mix with water

• Soil and paper debris are combined

• Loosely connected rocks bind together.

At which point is the slump block located?

• 1

• 2

• 3

• 4

Which factor influences the mass movement of particles?

• wind blowing across a body of water

• addition of vegetation to a slope

• large rocks and debris on a slope

• puddle of water resting on flat land

Which agent contributes to erosion?

• sunlight

• shorelines

• clouds

• ice and glaciers

Which process works with erosion to break down rock?

• deposition

• settling

• transportation

• weathering

Which factor most likely facilitates mass movement after heavy rains in a dry region?

• deposition

• mudflow

• slump

• weathering

Which phrase describes an example of mass movement?

• sediment settling on a mountain

• soil mixed with water sliding off a cliff

• wind blowing sand particles across a beach

• rocks breaking into sediment as they fall to the ground
