Describe how a volcano would form along a divergent boundary convergent boundary and hotspot

daser333 [38]

For divergent boundary: when the crust of the earth fractures it allows magma to reach the surface. For convergent boundary: When one of the converging plates move underneath the other, a process also known as subduction; the new magma rises and can erupt to form volcanos. For the Hotspot: magma pushes through cracks in the crust to form volcanos. Hope this helps!!
