Volcanoes form as molten rock erupts.
... Earth’s thin outer layer is made of cool rock, but most of Earth is made of extremely hot rock and molten metal. Some of the heat inside Earth escapes to the surface through volcanoes. A volcano is an opening in Earth’s crust through which molten rock, rock fragments, and hot gases erupt. A mountain ...

What IS A VOLCANO?
... through a volcano and come out as lava. The temperature of magma is extremely high while that of lava are lower as it cools down when it comes out under the atmosphere. The varying amount of heat causes a difference in their viscosity; magma's viscosity is lower due to immense heat inside earth. ...
