WebThe richer the silicates in the magma, the higher the temperature it produces. Lava is the material that comes out of volcanoes when an eruption occurs. Lava is formed from magma that melts and flows to the earth's surface. The process of forming lava is very complex and involves many geological and chemical factors. WebWhen a volcano erupts, ashes burst out of the vent together with magma and forms a cloud in the atmosphere.
