In deforestation, there is the cutting or the removal of plants. The roots of the plants allow the soil to be held due to the presence of water. Due to deforestation, the water present in the soil gets evaporated resulting in a barren land. This barren land is prone to soil erosion which results in the loss of the upper layer of the soil. When new trees are planted, the soil erosion can be prevented. 

The process of soil erosion is the washing away of the upper fertile layer of the soil. The roots of the trees and plants are responsible for holding the soil. When there is heavy rain and there are no plants in the area, the layer of the soil gets carried away along with the water. 

Roots of plants hold the soil particles and prevent their loss. Hence vegetation prevents soil erosion. When vegetation is lost and soil is kept barren after harvesting there is soil erosion due to the loss of upper soil layer caused by heavy wind or flowing water. Thus the correct answer is option B.

During heavy rainfall, trees act as a natural absorber. They prevent soil erosion, thereby reducing sediments going into rivers and increasing water absorption into the ground. But when the soil is without vegetational cover rainwater carries away the soil and causes its loss. Thus the correct answer is option B.

The roots of the plants allow the soil to be held due to the presence of water. Soil erosion is the loss of the fertile soil due to an absence of plants which can hold the soil. The farmers plant hedges across a field which prevents the carrying away of the soil during rain. 

Soil is formed as a result of weathering of rocks. There are also many living organisms in the soil. Soil is, in fact a product of the interaction of living organisms with rocks. Soil has many layers. The topmost layer is called the topsoil and is the most fertile. The removal of this topsoil is called soil erosion. Water and wind cause the topsoil to be removed. Soil erosion is mainly associated with deforestation and agriculture. The main cause of soil erosion is the removal of vegetation. 

Vegetation cover acts as a buffer, reducing the impact of raindrops and holding the soil together with roots, which is the most effective way to prevent erosion.

The surface layer of land is called as soil. Topsoil is the uppermost layer of the Earth's surface layers. Top soil is soft and light and can be carried away easily. Water and wind cause the topsoil to be removed. This process of carrying of top soil by wind and water is called as soil erosion.
