a.Laterite soil
b.Alluvial soil
c.Regur soil
d.Sandy soil

Answer 1

Hint: Soil is an important and beneficial resource for every human being on Earth. It is a mixture of rock fragments and organic materials, which develop on the earth’s surface. Soil is classified soils into 8 types by the Indian Council of Agricultural Research (ICAR), namely; Alluvial Soil, Black Soil, Red Soil, Laterite Soil, Mountainous Soils, Desert Soil, Alkaline Soil, Peaty, and Marshy Soil.

Complete Step by Step Answer:

The major components of the soil are mineral particles, humus, water, and air. They are classified based on their inherent characteristics and external features, that is, texture, colour, the slope of the land, and moisture content in the soil. The factors determining soils’ characteristics are;
- parent material
- climate
- relief
- vegetation
- time, and
- some other life-forms.

The black soil is a major type of soil which is found in Maharashtra, Gujarat, Madhya Pradesh , Chhattisgarh as well as in the valleys of Godavari and Krishna. This soil is rich in lime, iron, magnesium, alumina, and potash. It is clayey, and impermeable which enables it to retain the moisture for a very long period. It is ideal for growing cotton.

Black soil is also known as regur soil. The word "regular" comes from the Latin word regurgitate which means to overflow. Since this soil is formed as a result of lava flows, it is known as regular soil. Its colour varies from deep black to grey.

So, the correct option is C.

Note: The black soil also develops cracks which facilitate the aeration of the soil. The Soil Survey of India made a detailed study of soils in 1956 and the first scientific classification of soil was done by Vasily Dokuchaev.
