They happen because magma (inside earth) has to get out of the earth so it pushes land out and then magma turns into lava (outside earth). And then a volcano is formed.

Volcanoes form when magma from beneath the Earth's surface rises and erupts through a vent or opening in the crust. This can happen due to tectonic plate movements, hotspots in the mantle, or pressure buildup from magma chambers. The explosive release of gas, ash, and lava during an eruption is what we see as a volcanic event.
