true

3.

what is erosion?

a)

the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

what is deposition?

a)

a rock that moves with the wind

the layer of the atmosphere above the troposphere

11.

Which data set is easier to use to compare the rates of change

a)

converted data is easier to use because the units are different

b)

12.

what is sediment

a)

sediment fragments of organic or inorganic material that are transported and deposited by wind

b)

the natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate and decompose rocks
