Soil Erosion and Conservation

The components of soil include:

• clay

• silt

• sand

• shells

Most plants have trouble growing in soil with too much clay because:

• It doesn't hold enough water.

• It holds too much water.

• It is too sandy.

• It doesn't have enough nutrients.

__________ is a type of soil that contains multiple components in the right amounts, combining their advantages for plant growth.

• clay

• silt

• sand

• loam

The particles in soil are made up of:

• water

• roots and leaves

• tiny pieces of rock, nutrients, and minerals

• stems and roots

The type of erosion that happens from flash floods or other impromptu water is:

• rill erosion

• bank erosion

• sheet erosion

• wind erosion

A good way to protect a bare hillside from soil erosion is to:

• cover it with tarps.

• plant ground cover.

• heavily water it.

If experts are suggesting using terracing to stop soil erosion, the area is likely to be:

• a forest.

• a desert.

• a hill.

• a swamp.

Two main forces of erosion are:

• rain and snow.

• wind and water.

• sunlight and wind.

• pH and salinity.

Crop rotation protects against soil erosion by:

• reducing the risk of brush fires.

• reducing wind exposure to crops.

• giving water time to seep back into the soil.

• planting different crops on the same land, so nutrients can be replaced over time.
