Soil Erosion Quiz

What is erosion?

• The process of building roads and cities that lead to soil erosion

• The process of farming that reduces soil erosion

• The process of planting trees to prevent soil erosion

• The process by which the surface of the earth is worn away mainly by the action of wind, water, and glacier

What is the main cause of soil erosion?

• Planting trees

• Building roads and cities

• Wind, water, and glacier

• Crop rotation

Which human activities can lead to erosion?

• Farming, cutting down forests, building roads and cities

• Planting trees, crop rotation, conservation tillage

• Terrace farming, strip farming, contour farming

• Grass waterways, diversion structures, planting trees

What is raindrop or splash erosion?

• Erosion due to runoff of surface water along drainage lines

• Uniform removal of topsoil from the land surface by wind

• Erosion caused by falling rain drops on soil surface with crumbs

• Erosion observed during heavy rain through streamlits

What is sheet erosion?

• Uniform removal of topsoil from the land surface by wind

• Erosion caused by falling rain drops on soil surface with crumbs

• Erosion observed during heavy rain through streamlits

• Erosion due to runoff of surface water along drainage lines

What is rail erosion?

• Uniform removal of topsoil from the land surface by wind

• Erosion observed during heavy rain through streamlits

• Erosion caused by falling rain drops on soil surface with crumbs

• Erosion due to runoff of surface water along drainage lines

What is gully erosion?

• Uniform removal of topsoil from the land surface by wind

• Head ward destabilized erosion due to runoff of surface water along drainage lines

• Erosion caused by falling rain drops on soil surface with crumbs

• Erosion observed during heavy rain through streamlits

What is stream bank erosion?

• Erosion observed during heavy rain through streamlits

• Erosion caused by falling rain drops on soil surface with crumbs

• Washing up of soil away from banks of a stream or a river

• Uniform removal of topsoil from the land surface by wind

How can soil erosion be reduced?

• Farming, cutting down forests, building roads and cities

• Terrace farming, strip farming, grass waterways

• Planting trees, diversion structures, stream bank erosion

• Crop rotation, conservation tillage, contour farming

What is the effect of soil erosion?

• Loss of topsoil, soil compaction, reduced organic matter

• Increased vegetation, crop rotation, conservation tillage

• Terrace farming, strip farming, grass waterways

• Diversion structures, stream bank erosion, rail erosion
