400

What causes deposition to have a layered look?

Sediment settles according to its weight. The heaviest sediment drops first, and the lightest sediment drops last. forming layers.

400

What are decayed organic material found in soil called?

humus

400

deflation

400

Unweathered rock that influences the soil above it is called _______.

a. topsoil

b. bedrock

c. subsoil

d. loam

b. bedrock

500

A _______ is an example of erosion that is caused by gravity.

a. deflation

b. moraine

c. sand dune

d. rockslide

500

If a stream has a wide path is changed to a much narrower one, how will this affect the erosion?

The stream will increase in speed, causing the water's ability to have a heavier load and cause more erosion.
