The correct answer is: b) Sedimentary rocks.
Sedimentary rocks are formed from the accumulation of sediment, which is material that has been transported by water, wind, or ice and then deposited. Sediment can be made up of pieces of other rocks, minerals, or organic matter. Over time, the sediment is compacted and cemented together to form sedimentary rock.
The Eastern Ghats are a mountain range that runs along the eastern coast of India. They are composed of sedimentary rocks that were deposited during the Precambrian and Paleozoic eras. The rocks in the Eastern Ghats are mostly sandstone, shale, and limestone.
Igneous rocks are formed when magma or lava cools and solidifies. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface. Igneous rocks can be classified into two types: intrusive and extrusive. Intrusive igneous rocks are formed when magma cools and solidifies beneath the Earth’s surface. Extrusive igneous rocks are formed when lava cools and solidifies on the Earth’s surface.
Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. The heat and pressure can cause the rocks to change their shape, texture, and composition. Metamorphic rocks can be classified into two types: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance. Non-foliated metamorphic rocks do not have a layered or banded appearance.
Volcanic rocks are formed when magma or lava erupts from a volcano. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface. Volcanic rocks can be classified into two types: extrusive and intrusive. Extrusive volcanic rocks are formed when lava cools and solidifies on the Earth’s surface. Intrusive volcanic rocks are formed when magma cools and solidifies beneath the Earth’s surface.
