Plate tectonics is about thin oceanic plates knocking against larger continental plates. When both plates are pushed against each other by thermal actions of the underlying magma then the oceanic plates goes under the continental plate. As it is pushed down it melts and forms magma that rises to the surface and the magma pushes its way through the continental plate and creates volcanoes. The more the oceanic plate is pushed under the continental plate, the greater the potential for more volcanoes and more volcanic activity. Volcanoes can occur under the sea when two oceanic plates come together as well. This action can cause volcanic islands to form.
What else can I help you with?
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
Why does Japan have volcanoes?
Japan has volcanoes because it lies on the edge of the Pacific tectonic plate which is being shoved under the Asian plate. As the Pacific plate descends. the increasing heat causes the rock to melt and volcanoes to erupt.
Why do you need to study volcanoes?
study volcanoes to know when they will erupt to save people's lives and some like to study volcanoes to learn more about tectonic plate movement.
Were can volcanoes erupt?
Along plate boundries.
What kind of tectonic plate is mt.erebus?
Mt. Erubus has tectonic plates made up of parts of the lithosphere. These plates grind together or pull apart and this causes volcanoes to erupt.
When are Volcanoes and earthquakes are likely to occur?
They are more likely to occur on places/countries that are on Tectonic plate boundaries. This is because a tectonic plate boundary is when earth is raised above the normal level causing the ground to shake. When the earth rises it can form small volcanoes that get bigger and it will erupt a lot after then. :D
Where do volcanoes commonly erupt?
In areas of tectonic activity and above mantle plumes.
What is the most common place a volcano might erupt?
There is a region in the Pacific Ocean called the Ring of Fire, and it is home to many of the world's earthquakes and volcanoes. It has 452 volcanoes and it is home to 75% of the world's dormant and active volcanoes. Besides that, many islands and island nations have volcanoes, such as Hawaii and Japan. Also, 80-90% of all volcanoes occur near tectonic plate boundaries that spread apart.
How can volcanoes errupt under water?
Volcanoes can erupt underwater when magma rises to the surface through a weak spot in the Earth's crust on the ocean floor, known as a mid-ocean ridge or a hotspot. When the magma reaches the cold ocean water, it can cause the water to heat up rapidly, leading to explosive eruptions and the formation of underwater volcanoes.
Where do volcanoes errupt the most?
Where there is a tectonic plate boundary
What makes Hawaiian volcanoes erupt?
Nature. with plate tectonics and stuff
When are island arc volcanoes formed?
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
