Answer:
soil erosion :-
>> Natural events like wind , rain and flood carry away the topsoil with them, from one place to another. This process is called soil erosion. Soil erosion is likely to occur when no plants are rooted in the soil as roots of plants hold soil particles together. When the fertile topsoil is eroded, the less fertile subsoil comes to the surface which leads to a fall in crop production.
Gradually, the land loses its fertility and becomes barren.
