Effects of Gravity on Erosion

How does gravity contribute to the process of erosion?

• By pushing rocks uphill

• By pulling rocks and soil downhill

• By stopping the movement of glaciers

• By creating sand dunes

What is the result when sediments are dropped in new places?

• Erosion

• Deposition

• Weathering

• Melting

Which landform is created when a river deposits sediments at its end?

• Canyon

• Valley

• Delta

• Glacier

What happens to the land as a glacier moves over it?

• It becomes steeper

• It flattens

• It becomes a desert

• It forms a sand dune

How do sand dunes form?

• By water depositing sediments

• By wind depositing large amounts of sand

• By glaciers carving out land

• By gravity pulling rocks downhill

What role does wind play in the process of erosion and deposition?

• It melts glaciers

• It carries and deposits sediments

• It stops rivers from flowing

• It pushes rocks uphill

Which of the following is NOT a result of gravity's effect on erosion?

• Rocks falling from mountain sides

• Glaciers moving and flattening land

• Formation of sand dunes

• Rocks and soil being pulled downhill

What is a glacier?

• A fast-moving river

• A large mass of slow-moving ice

• A type of sand dune

• A small hill formed by wind
