How do volcanoes form?

Volcanos begin to form beneath the ground that we walk on. Many, many football fields below the Earth, a substance called magma forms. Magma is extremely hot and red in color. Magma is a very important part of the volcano because magma is what creates lava that erupts from the volcano. Magma flows all around the volcano and sometimes escapes from the sides before it gets a chance to erupt as lava.
