Solution
The correct options are
A Rainfall
B Overgrazing
C Reduced vegetation cover
∙ Rainfall, overgrazing and reduced vegetation cover are the causes of soil erosion. When the rainfall hits the ground, it loosens the top soil and creates a water runoff which carries the soil with it and deposits it elsewhere.
∙ If the cattles are allowed to graze repeatedly from the same field, along with the grass, they will also eat the roots which will make the top soil vulnerable to the flowing water and wind, resulting in the erosion of the soil.
∙ Reduced vegetation cover causes the top soil along with the organic matter to be blown away by the heavy wind which causes soil erosion.
∙ Afforestation is the method of planting trees as roots of the trees hold the soil which prevents the soil erosion.
