Question

Why can volcanoes form at convergent boundaries? (1 point)

Answer 1

Volcanoes can form at convergent boundaries due to subduction, where one tectonic plate is forced beneath another plate into the Earth's mantle. As the subducting plate descends, it undergoes increasing temperatures and pressures, causing the release of water and other volatile substances. These volatiles rise into the overlying mantle wedge, decreasing its melting point and causing the rock to partially melt. This molten rock, or magma, then rises to the surface, erupting as a volcano.
