Detailed explanation-1: -The major causes of soil erosion are namely, deforestation, overgrazing, forest fires and poor farming techniques. Hence the statement is correct.
Detailed explanation-2: -Deforestation. Without plant cover, erosion can occur and sweep the land into rivers. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion.
Detailed explanation-3: -The given statement is false. Deforestation causes a decrease in water holding capacity which results in soil erosion and floods. This happens due to the removal of plants, as plant roots hold water and prevent soil erosion and floods.
Detailed explanation-4: -Which of the following statements is/are true with reference to soil erosion? Deforestation exposes land to the forces of wind and water leading to loss of topsoil and nutrients.
Detailed explanation-5: -Deforestation reduces biodiversity by disrupting the hydrologic cycle, destroying habitat, causing soil erosion, and, in extreme cases, can lead to desertification. Thus, the loss of biodiversity does not cause deforestation. Thus, statement 4 is incorrect.
