Deep inside the earth, there are hot molten rocks that are called magma. Magma is the molten natural material from which igneous rocks are formed. A volcano or a rupture in a planet's surface allows hot-molten rocks to escape from below the surface.

The two blocks of earth suddenly slip past one another, it gives rise to an earthquake and the surface where they slip is called a fault. This causes shakes and tremors deep below the surface of the earth and gradually rise an earthquake.

A volcano is formed when the gas, pieces of rocks, ash and lava erupt from the vent. When magma erupts through the earth's surface, it is called lava. Some eruptions are quiet, where lava comes out gently. Some are quite explosive, when lava comes out violently. On cooling, it forms a volcanic rock. The hollow top of the volcano that is shaped like a bowl is called a crater.
