Answer 1

Answer:

Extrusive rocks are formed by the molten lava which comes out of volcanoes, reaches the earth’s surface and cools down rapidly to become a solid piece of rock. For example, basalt.

Intrusive igneous rocks

When the molten magma cools down deep inside the earth’s crust, the solid rocks so formed are called intrusive rocks. For example, granite.
