At constructive boundaries, magma from the earth's interior rises to the surface and forms mostly fissure volcanoes, but a few other tyopes as well, and forms new crust which pushes away older crust
At destructive boundaries, in a process called subduction, an oceanic plate slides into the earth's mantle, where it melts. The molten roick then rises to the surface and fornms a chain of volcanoes, mostly stratovolcanoes, but a few of other types as well

BlakeAt constructive plate margins, tectonic plates move apart, creating space for magma to rise from the mantle. As the magma reaches the surface, it erupts and forms volcanic activity. Over time, repeated eruptions build up layers of volcanic material, leading to the formation of a volcano.

Why do volcanoes occur at constructive plate margins and subduction zones?
Volcanoes occur at constructive plate margins because as tectonic plates move apart, magma rises to the surface, creating new crust. In subduction zones, volcanoes form when one tectonic plate is forced beneath another, melting the crust and generating magma that erupts as volcanoes.
Did plate tectonics on Mars form the volcanoes on Mars?
No. Mars does not have plate tectonics. The volcanoes on Mars are the result of hot spots.
Where does cinder cone volcanoes form?
cinder cone volcanoes usually form around lithospheric plate boundaries.
Do plate movements help drive the rock cycle to form volcanoes?
Yes. Most volcanoes on Earth are associated with plate boundaries.
Volcanoes form on what plate?
Volcanoes form on tectonic plates at plate boundaries where magma from the Earth's mantle can rise to the surface. This typically occurs at divergent or convergent plate boundaries where there is movement and interaction between the plates, leading to volcanic activity.
