Question

Give a geographical reason for different regions in India having different kinds of soil.

Answer 1

HintTemperature and precipitation are the two main primary climatic factors that make soils different from each other. Precipitation determines the amount of water that moves through the soil and minerals and salts dissolve in, and move with, the water. Soils also differ from one another in the context of the shape of the landscape, or relief.

Step by step solutionVarious factors such as nature of parent rocks, temperature, humidity, rainfall, etc determines the nature of the soil. India possesses a massive longitudinal and latitudinal extent and that's the primary reason for every region experiencing different climatic conditions. Therefore, different regions consist of different types of soil. For example - In the Northern Indian Plains, Alluvial soil is present and has been formed due to the erosional transportation and depositional activities of the Himalayan rivers. Deccan Plateau contains the black soil which has been formed due to the weathering of flour followed by cooling off the flower. After a volcanic eruption takes place, the soil is ready to be used for growing cotton. Rajasthan usually has low rainfall. Therefore the soil present is Sandy which does not promote extensive agriculture.

NoteConsidering the genesis, color, composition, and location, the soils of India have been grouped into Alluvial soils, Black soils, Red and Yellow soils, Laterite soils, Arid soils, Saline soils, Peaty soils, Forest soils. Lighter colors of soil are usually associated with younger soils because of the presence of low organic matter accumulation. Oder soils are redder as they have had time to accumulate iron oxides.
