Weathering and agents of erosion

Agents of erosion include

Agents of erosion include

All of the above (gravity, wave, ice)

Erosion is always followed by

Deposition

Factors that determine how much erosion runoff can cause include

all of the above (how fast the water is moving, how much water is flowing, whether the land is bare or covered with plants)

A waterfall forms when a stream flows

from harder to softer rocks.

When flowing water slows down, which of the following sediments does it drop first?

Gravel

Which statement about stalactites is false?

They form on the floors of caves.

What forms when a river erodes the outside of a curve and deposits sediments on the inside of the curve?

meander

Wind drops the sediment it is carrying when it

slow down

What is the first step in the formation of a sand dune?

Wind carrying sand strikes an obstacle.

A sand dune migrates because wind keeps

blowing sand up and over the dune.

Deposits called loess

all of the above (form vertical cliffs, have thick rich soil, are deposited by wind)

Loess deposits consist of

silt and clay.

Loess deposits are used for

farming

Soil is less likely to be eroded by wind if it is

Two of the above (covered with plants, surrounded by trees)
