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
What else can I help you with?
Why do volcanoes occur at constructive plate margins and subduction zones?
Because the subducting plate is water saturated oceanic crust, and as it moves down into the mantle it vaporizes the water and forces steam upwards. At the same time, the descending plate causes friction and circulation, leading to pressure-release melting. All of these processes melt the upper mantle to form magma chambers and thus, 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.

Why can volcanoes be constructive and a destructive?
Volcanoes can be constructive when they form islands and mid-ocean ridges
What is the constructive uses of earthquake?
There are very few constructive uses for an earthquake. One use is that an earthquake allows plate margins to form, however the destruction clearly outweighs any advantages.
What is a continental arc system?
These arc systems form at collision plate margins where an oceanic plate is being subducted under a continental plate. As the oceanic plate melts, the magma rises and finds cracks in the continental plate above and creates volcanoes. These volcanoes occur all the way along this plate margin. For example the cascade volcanic arc on the north west coast of USA.
What type of boundary plates produce volcanoes?
convergence plate boundary, where tectonic plates move towards each other and collide, leading to subduction zones which are highly constructive regions of volcanoes. Volcanoes also form at divergent plate boundaries. A good example being the numerous Icelandic volcanoes which have formed over he Mid Atlantic Ridge.
Which type of plate margins commonly form valcanoes?
tectonic plates
What are two Ways volcanoes Form near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.
What plate process causes volcanoes to form at their boundaries?
the plate of your mom
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?
