• rocks

• water

• humus

• chemicals

Chemical weathering changes a rock's

• pore space

• exfoliation

• texture

• composition

A fast flowing river wears away small particles from the rocks in its bed. This is an example of

• exfoliation

• abrasion

• rotation

• desertification

Which of the following affects the rate at which a rock weathers?

• contour

• surface area

• pore space

• texture

A rock will weather more quickly in a hot, wet environment than in a cold, dry environment. This is an example of how

• climate affects soil formation

• climate affects rock formation

• landforms affect soil formation

• landforms affect rock formation

In a soil profile,most organic material is foiound in the

• B horizon, which contains material washed down from above

• C horizon, which is the deepest layer of the soil

• A horizon, which is the upper layer of the soil

• the layer of dead leaves on the surface of the ground

Tropical, desert, temperate, and arctic soils all have different charaxteristics because of their different

• abrasions

• horizons

• climates

• landforms

Most of the matter that breaks down to form humus comes from

• rocks

• clay

• plants

• minerals

It is difficult for water to move through soil that has

• mostly large particles

• many earthworms and ant homes

• little or no pore space

• a high sand content

The way that water in the soil dissolves nutrients depends upon the

• terracing of the soil

• chemistry of the soil

• pore space of the soil

• texture of the soil
