Detailed explanation-1: -The soils of the plains have not been derived only from the rocks existing locally. Plains are associated with high productivity due to the generally reliable summer precipitation, a long growing season, and deep, fertile soils.
Detailed explanation-2: -The correct answer is Alluvial Soils. Alluvial soil is the most widely spread and important soil. In fact, the entire northern plains are made of alluvial soil.
Detailed explanation-3: -Soil erosion is caused due to human activities like deforestation, overgrazing, construction, and mining. Soil erosion is also caused by natural forces like wind, glaciers, and water.
Detailed explanation-4: -The rivers originating from the Himalayas bring rich alluvial sediments down in the plains, creating the fertile alluvial soil.
