Question

Give geographical reason.

Most of the volcanoes are found on the plate boundaries.

Answer 1

Along plate boundaries, either plates sink below another plate (subduction), heating and creating magma, or plates pull apart, allowing magma to rise to the surface. In both these conditions, when the magma reaches the surface it creates volcanoes. Thus, most of the volcanoes are found on the plate boundaries. More than 400 volcanoes—about 80 percent of all active volcanoes above sea level—are along subduction zones in the Pacific Ocean. The volcanoes around the Pacific Ocean form a belt called the Ring of Fire.
