What is erosion and how can its effects be slowed?

• A. Erosion is the process of soil forming into rock.
• B. Erosion is the wearing away of Earth's surface by wind, water, or ice, and it cannot be slowed by vegetation.
• C. Erosion occurs only in very hot deserts.
• D. Erosion is the wearing away of Earth's surface by wind, water, or ice; it can be slowed by vegetation, retaining walls, and reducing erosion agents.

Answer: (D)

Erosion is the wearing away of Earth's surface by wind, water, or ice. Its effects can be slowed by keeping soil in place with vegetation—roots hold soil together and a leafy cover protects the surface from raindrops and strong winds. Building retaining walls on slopes helps prevent soil from sliding or washing away. Reducing erosion agents means managing how water and wind move the soil, such as using ground cover or mulch to slow runoff, shaping land with terraces or contour planting, and placing windbreaks like trees to cut down wind erosion. In short, erosion happens when soil is moved, but planting plants, building barriers, and reducing the forces that move soil can all slow that process.
