Final answer:
Volcanoes can form at thermal vents, divergent boundaries, convergent boundaries, and hot spots.
Step-by-step explanation:
Volcanoes are formed at various locations on Earth's surface. *Thermal vents are actually one type of underwater volcano, where molten lava erupts from the ocean floor. *Divergent boundaries are locations where tectonic plates move away from each other, creating volcanic activity. *Convergent boundaries occur where tectonic plates collide, resulting in the formation of volcanoes. *Hot spots are locations where magma rises to the surface through the Earth's mantle, creating volcanic activity.
