VOLCANOES There a lot of volcanoes on the Earth. A volcano is a mountain that forces hot gas, rocks, ash and lava into the air through a hole at the top. Some volcanoes are not immediately dangerous because they are not active and have become dormant. Others will never be dangerous again because they are completely extinct. Active volcanoes can erupt. Some of them erupt slowly and quietly. This slow eruption can last for months or even years. Sometimes volcanoes erupt very quickly and noisily. Under the surface of the earth it is very hot. The rocks are not hard and solid. They are thick and liquid. This liquid rock is called magma. Sometimes there is an opening in the rocks on the surface. Then magma can come up through this opening and the volcano erupts. Dust and pieces of rock are thrown up into the air. Red hot lava pours down the sides of the mountains. Later on, the lava cools and becomes hard rock.
