The correct answer is B. Wind erosion.
Wind erosion is the process by which loose soil is blown away by the wind. It is a major problem in Haryana, as the state is located in a semi-arid region with hot, dry summers and cool, dry winters. The wind can carry away the topsoil, which is the most fertile layer of soil. This can lead to a loss of productivity in agricultural land, as well as an increase in the risk of flooding and landslides.
Drought is a period of time with little or no rain. It can cause a number of problems, including crop failure, water shortages, and wildfires. However, drought is not the main problem of soil erosion in Haryana.
Earthquake is a sudden shaking of the ground caused by the movement of tectonic plates. It can cause a number of problems, including damage to buildings and infrastructure, loss of life, and landslides. However, earthquake is not the main problem of soil erosion in Haryana.
Flood is a natural disaster that occurs when water overflows its normal boundaries and inundates land. It can cause a number of problems, including damage to property, loss of life, and soil erosion. However, flood is not the main problem of soil erosion in Haryana.
Wind erosion is the main problem of soil erosion in Haryana because of the state’s location in a semi-arid region with hot, dry summers and cool, dry winters. The wind can carry away the topsoil, which is the most fertile layer of soil. This can lead to a loss of productivity in agricultural land, as well as an increase in the risk of flooding and landslides.
