Why do some parts of the world have lots of volcanoes and other parts
of the world have no volcanoes?

The distribution of volcanoes is largely influenced by tectonic plate boundaries. Volcanoes often occur at convergent plate boundaries, where two tectonic plates collide, causing one to be forced beneath the other in a process called subduction. This subduction leads to the melting of rock in the Earth's mantle, creating magma that eventually erupts at the surface as volcanoes.

Other types of plate boundaries where volcanoes can form include divergent plate boundaries, where plates move apart, allowing magma to rise and create new crust, and hot spots, where magma from deep within the Earth rises through the mantle and erupts at the surface.

Areas with no volcanoes are typically located away from plate boundaries or hot spots, where the conditions for volcanic activity are not present.
