Question

Among the following soils, which one is formed through the typical monsoonal conditions?
(A) Black Soils
(B) Red Soils
(C) Laterite Soils
(D) None of these

Answer 1

Hint: Soil minerals are forming the basis of soil. These are produced from the rocks i.e. parent material through the processes of weathering and other natural erosion. Also, water, wind, temperature change, gravity and chemical interactions are helping to break down the parent material.

Complete answer:
Black soils are formed by the weathering or breaking of the igneous rocks. Also being formed due to cooling or solidification of lava from the volcano eruption.
Red soils are formed by the weathering of ancient crystalline and the metamorphic rocks. In particular formed through the acid granites and gneisses, quartzitic rocks as well as feldspathic rocks.
The laterite soil is generally being developed in areas with high temperature and heavy rainfall. And therefore, it results in the intense leaching due to heavy rain. Due to such a dry climate, high temperature, evaporation is being done faster. This makes soil lacking humus and moisture. Laterite Soils are formed under typical monsoonal conditions.

Therefore, the correct answer is option (C).

Additional Information:
Soil is the natural resource which can be categorised into the different soil types. Each of these is having distinct characteristics providing the growing benefits and limitations. Soil further can be categorised into the sand, clay, silt, peat, chalk and loam etc.

Note:
Climate is probably the most important factor which can shape the formation of soils. These determine how quickly weathering will be. Also, these are determining what kind of organic materials may be available on and inside of the soils. Moisture also determines the chemical and biological reactions which will occur as the soils are formed.
