Soil Erosion

There are two basic causes/methods of Soil Erosion

• Wind and Water

• Glaciers and Land Slippage

• Slope and Soil Cover

• Geological and Accelerated

• None of the above

All Accelerated erosion is caused by man made activity

• True

• False

Wind Loss erosion happens

• When the ground is wet

• In dry conditions

• When there is a lot of ground cover

• Glaciers

• All of the above

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

• All of the above

• 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

• None of the above
