How does valcano occur?

Answer 1

Volcanoes occur when two techtonic plates come together, like an earthquake- which sometimes causes the formation of a volcano, push through the crust.

Answer 2

Volcanoes occur when there is a rupture in the Earth's crust, allowing magma to rise to the surface. This magma can erupt explosively or flow out more gently, forming different types of volcanoes. Volcanic activity is driven by the movement of tectonic plates and the melting of rock beneath the Earth's surface.
