The question Why do Volcanoes erupt? When rock inside the Earth

becomes hot enough it melts. Just as an object that is less dense than water will float on water, the relatively low density of the magma causes it to rise to the surface of the Earth.

• Most volcanoes form under the water on the seafloor. Each time these time volcanoes erupt, they grow a little taller.
