Final answer:
Volcanoes can form at divergent and convergent plate boundaries, as well as at hot spots. Divergent plate boundaries occur when plates move apart, creating reduced pressure conditions that allow magma production. Convergent plate boundaries involve one plate subducting beneath another, releasing water and forming magma. Hot spots, which are areas far from plate boundaries, also contribute to volcanic activity.
Step-by-step explanation:
Volcanoes are formed at different types of plate boundaries. Divergent plate boundaries, where tectonic plates move apart, can lead to the formation of volcanoes. This happens when the underlying region of the mantle experiences reduced pressure conditions, allowing magma to be produced. Convergent plate boundaries, where tectonic plates collide, can also result in volcanoes. In these cases, one plate subducts beneath the other, causing the release of water and the formation of magma. Lastly, hot spots, which are areas far from plate boundaries, can generate volcanic activity. Hot spots occur due to heat rising from the Earth's interior and can produce volcanoes like those found in Hawaii.
