4. Where do volcanoes occur?
Volcanic Belts: Near plate boundaries

5. 3 Main Locations for Volcanoes
Divergent Boundaries
Mid-oceanic ridges and rift valleys
Subduction zones
2 oceanic plates meet
Forming Island Arcs
Oceanic and continental plates meet
Forming continental volcanic mountain ranges
Hot Spots: Area of high heat and low pressure that melts the earth’s crust forming a volcano
