Question

Which one of the following statements concerning soil erosion is not true?

Answer 1

Answer:

(a)-Rills, and arroyos or gullies develop mainly during prolonged droughts.

Explanation:

Soil erosion is the process of erosion, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents such as water, winds and living things. The process of disintegration of rock particles (called sediments) is caused by the action of weathering (a set of chemical, physical and biological processes that cause soil and rock wear).

About soil erosion, we can confirm that the following information is true:

• Grasses and other vegetation, windbreaks, and contour cropping will help reduce soil loss from cultivated lands.
• Soils form naturally by weathering; if protected from erosion, sound management can maintain or enhance their nutrient levels and textural characteristics.
