Volcanoes are the natural way that the earth and other planets cool themselves. Inside the planets are very hot, when there is a volcanic eruption, the internal heat will escape. When lava and gas escape, volcanic eruption occurs. Some volcanoes only work for a short time. Some exist for a long time, sometimes up to hundreds of thousands of years or several million years.
When spraying, the temperature of lava is about 1,200 degrees Celsius. Its temperature depends on the material composition of soil and rock.
Due to the heat inside, in some places, the heat melts ice into solution (magma). Volcano sprayed because of pressure. The more liquid the magma is, the easier it is to boil and rise to the surface, the magmatic bubbles form the gas. The greater the pressure of the gas, the higher the magma sprayed in space.
