Most volcanoes are found near tectonic plate boundaries because that's where the magma is located.

Question

Quizplus · Accepted Answer

Volcanoes occur at plate boundaries because at these locations, the Earth's crust is either being pulled apart or pushed together, creating an area of weakness where magma can reach the surface. This process is known as plate tectonics. However, there are also "hot spots" in the Earth's crust where magma can rise to the surface, such as the Hawaiian Islands, which are not located near plate boundaries.
