Erosion and Deposition

Which phrase best describes the process of erosion?

• breaks sediments into smaller pieces

• transports sediment to a new location

• works with deposition to carry away rocks

• adds sediment to a new surface where it settles

Which agent contributes to erosion?

• sunlight

• shorelines

• clouds

• ice and glaciers

Which process works with erosion to break down rocks?

• deposition

• settling

• transportation

• weathering

Which sediment would have the slowest rate of deposition?

• a round sediment

• a very large sediment

• an irregularly shaped sediment

• a high-density sediment

Which event occurs after erosion of Earth's surface?

• surface material breaks down into smaller pieces

• very dense particles settle faster than low-density particles

• large particles are carried away to a new location by ice and glaciers

• round particles form new landforms more slowly than flat particles do

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

• it allows sediment 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 new location

Sediments are carried from a hilltop to the ground at the bottom of the hill on a windy day. What is the agent of erosion?

• the hilltop

• the ground

• the sediments

• the wind

In the cycle that shapes Earth's surface, which event must happen before erosion can occur?

• deposition

• settling

• transportation

• weathering

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 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
