Erosion Review

What is the movement of soil from one place to another?

• weathering
• deposition
• discharge
• erosion

Which landform is formed because of the erosion of groundwater?

• valley
• canyon
• channel
• cave

What causes a valley like the grand canyon to form?

• earthquake
• running water
• landslide
• erosion by wind

What force is responsible for erosion and deposition in landslides?

• gravity
• ice
• wind
• temperature

A creep is formed from what agent of erosion?

• gravity
• glaciers
• oxidation
• wind

Rain washing away soil from a hillside is an example of

• Weathering
• Erosion
• Deposition

A satellite image of an area in Florida shows a river with slight bends along its length. A second satellite image taken of the same area 10 years later shows the same river with  a different course. What is the best explanation for the difference in the shape of the river's course between the two satellite images?

• Wind blew waves across the water surface, eroding away the bank on one side of the river until the river's course changed its shape
• Regular freezing and thawing of the river split the soil along the river banks, changing the shape of the river
• Water eroded the banks of the river and deposited the eroded soil on opposite banks, causing the river to form tighter bends
• Acid rain chemically weathered the banks along the river, forcing the river to wind back and forth

As you were climbing a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What 2 processes did you observe?

• Weathering and erosion
• Erosion and deposition
• Abrasion and chemical weathering
• Abrasion and ice wedging

Your teacher filled a box with sand. She put a fan at one end and turned the fan on. The sand was blown to the opposite side of the box and collected at that side. What 2 processes was the teacher demonstrating?

• Weathering and erosion
• Weathering and deposition
• Erosion and deposition
• Chemical and mechanical weathering

Glaciers shape and carve away the land beneath them and can drastically reshape the landscape over hundreds or even thousands of years.
