Erosion Review

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

• weathering

• deposition

• discharge

• erosion

A satellite image of an area in Ohio 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

Mud and sediment sliding down a hillside is an example of

• Weathering

• Erosion

• Deposition

Which particles will be transported by a stream moving at a velocity (speed) of 5 cm/s?

• pebbles, sand, silt, and clay, only

• sand, silt, and clay, only

• silt and clay, only

• clay, only

Compared to the stream speed between point X and point Y, the stream speed between point Y and point Z is most likely

• greater, since the slope of the land decreases

• greater, since the slope of the land increases

• less, since the slope of the land decreases

• less, since the slope of the land increases
