Question

Maharashtrian Plateau is made up of _____.
A. Alluvial soil
B. Coral reef
C. Basalt rock
D. None of these

Answer 1

Hint:
It is one of the forms of igneous rock. It is formed from the process of cooling lava which is rich in iron and magnesium. Its composition includes plagioclase, amphibole, pyroxene, feldspathoid, and olivine.

Complete answer:
Maharashtra is located in western India. The capital of the state in Mumbai. The Maharashtrian plateau is made up of Basalt rock. The Basalt rock can be defined as the mafic extrusive igneous rock. This type of rock covers more than 90% of all the volcanic rock on the surface of the earth. Lava is a type of molten rock. There are several types of lava such as Silicate lava, Felsic lava, intermediate lava, and Mafic lava. The Basalt rocks are rich in magnesium oxide and calcium oxide but less in Silicon dioxide. The basalt rock is mostly found in the large igneous provinces.

Most of the earth’s oceanic crust is made of igneous rock. There are two types of igneous rock namely intrusive such as plutonic and hypabyssal and extrusive such as volcanic.

Additional Information – In the solar system, the basalt rock mostly erupts in Mars, Venus, Moon, and the asteroid vesta. Mars is the fourth planet, Venus is the second planet. It is also called the morning and evening star. Vesta is the largest object in the asteroid belt. It was discovered by Heinrich Wilhelm Matthias Olbers.

Hence, the correct answer is option C.

Note:
The Basalt rock is used in the construction of building blocks or it is used in the groundwork. Some important types of basalt rock include Columnar basalt and Pillow basalt. The cobblestones are obtained from the columnar basalt.
