Question

What leads to the formation of laterite rocks?
A. Heavy Rainfall
B. High Temperature
C. Soil getting soft and dry up
D. None of these

Answer 1

Hint:Laterite can be used for both soil and a type of rock and mostly it is in rusty-red color because it is rich in iron and aluminum. The areas where laterite rock and soil type can be found is between tropics of Cancer and Capricorn.

Complete answer:Laterite can be used for both soil and a type of rock and mostly it is in rusty-red color because it is rich in iron and aluminum. The areas where laterite rock and soil type can be found is between tropics of Cancer and Capricorn. They are formed by the leaching of the parent rocks which can be sedimentary rocks, metamorphic rocks, and igneous rocks. They are formed in places that have a repetition of hot and dry climates.
- Option A: These types of rocks cannot be formed in regions of heavy rainfall as they require the during up of the surface beneath the earth’s crust. Hence, this is an incorrect option.
- Option B: These types of rocks cannot be formed in the regions of High temperature as they require water that seeps into the ground and regions of high temperature don’t have enough rainfall so the water won’t seep into the ground. Hence, this is the incorrect option.
- Option C: These types of rocks are formed when the soil gets soft because the water leaches the rock during the rainy season and the resulting solution is brought up to the ground when there is a dry season due to capillary action. Hence, this is the correct option.

So, the correct answer is option C.

Note:It is found in hot and wet tropical regions between the Tropics of Cancer and Capricorn and is developed due to prolonged and intensive weathering of the parent rocks that are underlying. It is mostly used for monument building as they are cut into brick-like shapes.
