The Deccan Plateau is largely made up of which type of rock formation?

Correct option is B

The correct answer is (B) Igneous rocks.

Explanation:
The Deccan Plateau is primarily composed of igneous rocks, specifically basalt rock, which is formed by volcanic activity. The plateau was shaped by extensive volcanic eruptions during the Cretaceous period and the basaltic lava flows that spread across a large portion of central and southern India. This volcanic origin gives the Deccan Plateau its unique landscape.

Information Booster:

• Igneous rocks are formed from the cooling and solidification of molten material (magma or lava). In the case of the Deccan Plateau, it is predominantly made up of basalt rock, which is an igneous rock.

• The plateau is part of the Peninsular Plateau and spans several states, including Maharashtra, Karnataka, Andhra Pradesh, and Telangana.

• Deccan Traps: The plateau is sometimes referred to as the Deccan Traps, which refers to the vast layers of basalt formed by volcanic eruptions that occurred millions of years ago.

• The plateau is known for its fertile soil due to the weathering of basalt rocks, making it ideal for agriculture, especially in areas like Maharashtra.

Additional Knowledge:

• Metamorphic rocks: Formed by the alteration of existing rock under high temperature and pressure, not the primary composition of the Deccan Plateau.

• Fossilised rocks: Fossils are found in sedimentary rocks; however, the Deccan Plateau's primary composition is igneous rather than fossil-bearing rocks.

• Sedimentary rocks: These are formed by the deposition of material in layers, commonly found in regions like riverbeds and coastal areas, but not dominant in the Deccan Plateau.
