How Volcanoes Erupt?

Answer

A volcano erupts when the Earth's tectonic plates begin to shift and force molten lava up into the mouth of the volcano. These plates can remain dormant for millions of years, but any movement in them can cause lava to spew destructively from the volcano.

The reason that volcanoes erupt is a pretty simple concept. It's similar to having a bottle full of water with the cap off. If it is squeezed tightly the water will have no choice but to come out the top. We know heat makes things expand, so as magma below the surface expands it comes out through a vent in a mountain, known as a volcano.
