In the inner part temperature is sufficient to melt iron, nickle, aluminium, etc. The molten was inside the earth is called magma. This magma came come out of the cracks and weak rocks above it. The coming out of molten mass from inside the earth is called volcano. The mouth of the volcano is called crater. As. the molten mass come out is calleed larva. The larva gets collected near the mouth volcano. The deposition of such molthen mass may from a hillock or mountain called volcanic mountain.

The volcanoes are not always active. Some volcanoes erupt at the particular time of every year. There are two type of volcano, active volcano and passive volcano.
