Where Do Volcanoes Come From?

Normally volcanoes are found over on the following spots;
1. Where tectonic plates pull apart. For example mid-oceanic ridges, like the Mid-Atlantic Ridge is pulling apart and is divergent tectonic plates.
2. Where tectonic plates are coming together; the Pacific Ring of Fire coming towards each other; and are convergent tectonic plate.
3. The stretching of the Earth's crust creates non-hotspot intraplate volcanoes. For example the Rio Grande Rift in North America, the African Rift Valley, the European Rhine Graben, and the Wells Gray-Clearwater Volcanic Field.
4. Volcanoes may be hotspots; these hotspots are not on the plate boundaries and even are found very far away from tectonic plate boundaries. For example Hawaiian Islands.
5. Volcanoes are found outside our globe on solar system in form of Hot spot volcanoes and are viewed especially on Mars and moons.
6. Submarine volcanoes are found on the ocean floor even in shallow waters. These are often recognized by blasting steam and rocky debris. These are very quiet volcanoes and many are lie deep in the sea floor and are recognized by the volcanic gas and discoloration of water.

Volcanoes come from many different places like hot spots and mid-ocean ridges.

From the earth ,movement of land. This happens when lava erupts from a mountain which results in increase in the height of the mountain.go to www.google.com for more information

Volcanoes come from under the ground

From the earth ,movement of land. This happens when lava erupts from a mountain which results in increase in the height of the mountain.

This happens due to the improper arrangement of earth. The hot gases inside were pressurised due to sudden changes of the earth layers and this leads to the eruption of lava which is nothing but hot melted rock. The common thing we observe in our life that when we put some force on a fully blown balloon on one side it explodes on the other side.
