Where do vocanoes form and why?

Answer 1

Volcanoes usually form between tectonic plates in the earth's crust. Hot molten rock beneath the surface gets pushed up as these plates move, and sometimes large rock formations will form. Volcanoes can form in places that arent on the edge of tectonic plates, however, but the Ring of Fire is where most of the earths volcanoes are concentrated, around the Pacific, North American, and South American plates.
