The correct answer is: c) Sedimentary.
Sedimentary rocks are formed from the accumulation of sediment, which is material that has been transported by water, wind, or ice. Sediment can be made up of pieces of other rocks, minerals, or organic matter. Over time, the sediment is buried and compacted, and it is eventually cemented together to form sedimentary rock.
The Meghalaya Plateau is a large plateau in northeastern India. It is made up of sedimentary rocks that were deposited over millions of years. The sedimentary rocks on the Meghalaya Plateau 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.
