Erosion Management

What is the process of moving sediments from location to another?

• Deposition

• Erosion

• Weathering

• Compaction

What is sediment?

• the process of rocks being broken down and carried away
• bits of rock, sand, and silt caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material 

Which of these is an example of erosion

• Light Shinning onto a mountain
• Rain breaking down rock 
• Wind blowing away sediment
• All of the above

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

How does vegetation in the soil affect the rate of erosion?

• It doesn't affect erosion.
• It decreases erosion.
• It increases erosion.

While most land areas are slow to change, the shape of beaches changes daily. Which of the following best explains this? 

• The heating and cooling of beaches changes the shape.
• Coastal animals change the shape of the shoreline.
• The wave action adds and removes sand daily.
• Sea level decreases each day, creating more coastal land.

According to the picture, name the type of the erosion?

• Rill Erosion

• Raindrop Erosion

• Sheet Erosion

• Gully Erosion

All factors below included in Universal Soil Loss Equation (USLE) except..

• A = Average Annual Soil Loss due to Sheet and Pile Erosion in Tons per Hectare per Year

• KS = Depth-Gradient Factor depends on Slope depth & Slope (%)

• C = Crop Management Factor = Crop Type Factor x Tillage Method Factor

• R = Rainfall & Runoff factor based on Geographical Location
