D. Due to its high fertility regions of alluvial soil are intensively cultivated

Answer 1

Answer:

answer (c) is not correct okay

Answer 2

" Option A) The soil develops in areas with high temperature and heavy rainfall ".

Explanation:

• Alluvial soil is one of the splendid soils, requiring the least water due to its high porosity. The consistency of alluvial soil ranges from drift sand and rich, loamy soil to silty clays. India is one of the richest countries in the world in terms of alluvial soil, which occupied more than 46% of its total land area.

• Alluvial soils are soils deposited by surface water. we can easily found the soil along rivers, in floodplains and deltas, stream terraces, and areas called alluvial fans.

• Alluvial soils basically remove sediments and nutrients flowing in the adjacent water.

• Alluvial soils are much fertile. alluvial soils contains an adequate proportion of potash, phosphoric acid, and lime which are ideal for the growth of sugarcane, wheat, and other cereal and pulse crops.

• This soil is a fertile soil as it is rich in minerals, especially potash and lime.

• Being one of the most important and fertile soils of India they support grow wide variety of crops such as Rice, wheat, sugarcane, cotton, jute, potato and vegetables.

• Minimum soil temperatures were 24.4, 20.2, and 19.1°C; and maximum were 39.0, 34.6, and 32.2°C, respectively. So, It doesn't develop in areas with high temperature.

• The laterite soils develops in areas with high temperature and rainfall.

• Hence, The alluvial soil couldn't develops in areas with high temperature and heavy rainfall. So, option A is not true
