Question
Why can volcanoes form at convergent boundary?
Answers
GPT 3.5
Volcanoes can form at convergent plate boundaries primarily because of subduction. Subduction occurs when two tectonic plates collide and one plate, usually a denser oceanic plate, is forced beneath the other plate in a process called subduction.
As the oceanic plate gets pushed deeper into the Earth's mantle, it starts to melt due to the increased temperature and pressure. The melted rock, known as magma, is less dense than the surrounding rock and therefore rises towards the surface. When the magma reaches the surface, it erupts as a volcano.
In addition to subduction, convergent boundaries can also result in volcanic activity due to the intense compression and fracturing of rocks. These fractured rocks provide pathways for the magma to reach the surface, resulting in volcanic eruptions.
Overall, the convergence of tectonic plates at convergent boundaries creates the necessary conditions for the formation of volcanoes.
