• moraine

• delta

• barrier island

• floodplain

Which agent of erosion is most likely responsible for the deposition of sandbars along ocean shorelines?

• glaciers

• mass movement

• wave action

• wind action

The cross section below shows the movement of wind-driven sand particles that strike a partly exposed basalt cobble located at the surface of a windy desert. Which cross section best represents the appearance of this cobble after many years of exposure to the wind-driven sand?

• 
• 
• 
• 

The photograph below shows an arch of rock located in the western United States. How did the arch most likely form?

• The bedrock in the arch was more resistant to weathering and erosion than the surrounding bedrock that was removed.

• An earthquake forced bedrock upward into the shape of an arch

• Sand and gravel were deposited and compacted in the shape of an arch.

• An underground glacier tunneled through the bedrock.

Which sediment is most easily picked up and transported by the wind?

• cobbles

• sand

• silt

• pebbles

A landslide is an example of

• river deposition

• glacial scouring

• mass movement

• chemical weathering

• tidal changes

• mass movement

• glacial erosion

• lava flow
