Virtually all of the world's volcanoes are located at the boundaries between tectonic plates.

It is most common to find volcanoes where an oceanic plate collides with a continental plate. It is the boundary between the Pacific Plate and the continental plates around it that is called the "ring of fire" because so many volcanoes are formed at this boundary.

In the collision the denser oceanic plate will be forced underneath of the continental plate. This is called 'subduction', and it usually occurs in destructive plate boundaries. Volcanoes are then formed, when the oceanic plate melts and the molten rock rises, being squeezed up by the forces of the mass above.

Volcanoes and volcanic activity occurs at plate boundaries. Especially when one plate over rides another plate - convergent boundary. As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries.

How do volcanoes help plate tectonics?

Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.


How did plate tectonics cause the formation of the hawaiian island?

The shifting of plates in the earth cause massive underwaer volcanic eruptions. Over time, the eruptions of the volcanoes cause a buildup of dried lava that eventually breached the surface of the ocean. These volcanoes are still erupting, causing the island to gradually grow.


How earthquakes volcanoes and mountain's formation are related to plate tectonics?

Earthquakes, volcanoes and mountains are formed via plate tectonics. When the large continental plates collide, they either cause temporary earthquakes, or more permanent features such as volcanoes and mountains.


Which of the terrestrial planets experiences PLATE tectonics?

The only terrestrial planet known to experience plate tectonics is Earth. Plate tectonics is the movement and interaction of large sections of Earth's lithosphere, and it plays a vital role in shaping the planet's surface and driving geological activity such as earthquakes and volcanic eruptions.


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.
