Answer: Intrusive rocks—
1. These are formed when cooling of magma take place below the surface of the Earth.
2. Beneath the surface, the molten rocks cools and hardens slowly.
3. The slow cooling allows us large crystals of minerals to form.
4. These rocks are very coarse grained.
Extrusive rocks—
1. These rocks are formed when magma is extruded or forced out,onto the surface of the earth.
2. The magma that reached the surface is known as lava.
3. As the lava cools down and solidifies rapidly on the surface,the minerals present in it form very small crystals.
4. These rocks are very fine grained.

Question. How sedimentary rocks are formed?
Answer:
1. Igneous rocks are exposed to the forces of nature such as wind,water and glaciers.
2. These forces break the rock on the surface of the earth into small pieces.
3. These small pieces of rocks are called sediments.
4. These small pices of rocks or sediments are carried by wind,rivers and glaciers and are deposited on the floors of lakes,seas or oceAnswer:
5. Layers upon layers of fine sendiments are collected.
6. Due to weight of the overlying layer,heat of the interior and chemical reaction, the sediments are compressed,cemented and hardened.
7. The rocks formed in this manner are called sedimentary rocks.

IV. Give reasons—
1. Igeneous are called primary rocks. Because all other rocks are directly or indirectly formed from them.
2. Sedimentary rocks are also called stratified rocks.
Because the deposition take place in layers.
3. Coal and petroleum called fossil fuels.
Because they were formed by the decomposition of remains of prehistoric plants and animals buried under the earth long, long ago.
