There are two main ways this can happen.
Where plates diverge the lithosphere is thin, meaning that there is less pressure over the stratosphere. This causes some material to melt and rise to the surface.
Where one plate subducts or slides under anotherit carries volatiles with it such as water. This lowers the melting point of mantle material. The molten material then rises to the surface.

What made volcanoes?
Volcano's are made by tectonic plate movements.
Where do volcanoes mostly form?
Volcanoes usually form where tectonic plates meet.
What causes mass movements?
tectonic plates. go to wikipedia to find out how tectonic plates relate to earthquakes, continental movements, and volcanoes
How do tectonic plates form volcanoes?
EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
Active volcanoes are most likely to form at .?
Volcanoes are most likely to form at the edges of the tectonic plates.
Why does magma aften form at the boundary between separating tectonic plates?
It is because volcanoes form by two tectonic plates which when both collide and they form volcanoes which a magma rock forms when it explodes.
What would happen if volcanic eruptions continued to occur on the sea floor?
There are volcanoes along the floor of the ocean that form a trench. When these volcanoes erupt, it can cause tectonic movements.
What two natural disasters come from plate tectonic movements?
Earth quakes and tsunami (also volcanoes)
Where do volcanos not form?
Volcanoes form on the ring of fire on the tectonic plates in the Atlantic Ocean so if you go further and further into the Atlantic Ocean there won't be volcanoes. And also on places that are miles from tectonic plates there won't be any there either. Just think if you were to go to a tectonic plate boundary there would be volcanoes now say you go 40 miles away from the tectonic plate there probably won't be volcanoes.
Where are volcanoes mountains and earthquake form?
Where two tectonic plates meet
Where in the world are volcanoes more likely to form?
Near tectonic plates:)
Do solitary volcanoes form as a result of hot spots?
the hotspots of volcanoes are when they are near tectonic plates when diverting or coliding
