Soils Unit Test

This is a diagram of

• layers of dirt

• soil

• different types of clay

• a soil profile

• None of these are correct

All Accelerated erosion is caused by man made activity

• True

• False

• Cannot tell given the evidence

Newly plowed fields are a source of wind erosion

• True

• False

• Could be both

Water erosion occurs

• By water carrying soil away

• Rain drops hitting bare soil

• Can be very slow or can happen very fast

• When soil is covered by plants

• None of the above

Land Slippage

• Occurs on sloping land

• Occurs on flat ground

• Is always a man made problem

• Occurs in dry conditions

• None of the above

The order of soil erosion is

• Deposition, Transport, Detachment

• Wind, Water, Glacial, Land Slippage

• Slope, Transport, Soil Cover

• Detachment, Water, Wind

• Detachment, Transport, Deposition

Detachment in Soil Erosion is

• When raindrops break up the soil

• Soil slips down a sloping area

• Is not a real thing

• When soil moves with water down a slope

• None of the above

Deposition in Soil Erosion is

• Where the soil deposited when the water slows down

• When rain breaks up soil

• the movement of soil with water down a slope

• man made activity

• All of the above

Four factors in soil erosion

• Structure and Texture, Slope and Soil cover

• Structure and Texture, Slope, Surface Roughness and Soil cover

• Wind Water Glaciers

• Land Slippage

• All of the above

Surface Roughness speeds up erosion

• False

• True

• Could be both
