Question:-

how are extensive and intrusive rocks formed?

Solution:-

Both extrusive and intrusive rocks are examples of igneous rocks. Extrusive rocks are formed when the molten magma present inside the earth's interior comes out onto the earth's surface, cools down and becomes solid on the earth's crust. These rocks have very fine grained structure. For example, basalt. When molten magma cools down and solidifies deep within the earth's crust, intrusive rocks are formed. Since they cool down slowly, they form large grains. Granite is an example of such a rock.

Additional information:-

The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
