High Five Facts - Soil Erosion

The video tutorial explains soil erosion, highlighting four main types: splash, sheet, real, and gully erosion. It discusses the importance of topsoil, its role in agriculture, and how erosion affects it. The video also covers natural defenses against erosion, such as plants and trees, and farming techniques like contour farming to prevent erosion. Finally, it addresses how erosion can lead to dust storms, emphasizing the environmental impact.

Which type of erosion is characterized by raindrops displacing soil?

• Sheet erosion

• To provide a habitat for insects

How do plants help in preventing soil erosion?

• By absorbing all the water

• By increasing soil acidity

• By trapping soil with their roots

• By blocking sunlight

What farming technique is used to prevent soil erosion on slopes?

• Vertical planting

• Contour planting

• Circular planting

• Random planting

What environmental issue can arise from dried-out topsoil?
