Volcanoes occur where they do because of the position of the crust over a plate boundary or a 'hot spot' in the Earth's mantle.
Continental volcanoes form when subducted crust melts to magma against the mantle, then is forced upward under pressure through cracks in the rocks above.
Sea volcanoes occur where the oceanic crust is heated from below as it moves over a "hot spot" in the mantle. The liquefied rock is pushed up into the ocean, where it solidifies, notably into a volcanic atoll or island. The islands of Hawaii have all formed from the same hot spot as the crust moved generally NW over millions of years.
Volcanism is also present at divergent plate boundaries, which may be located at mid-ocean ridges, or rifts on continents. The pulling apart of two plates at these locations causes rift volcanism and the upwelling of melting decompressed asthenospheric mantle material, creating new crust.
Earthquakes and volcanoes occur because of the plates. If land is sitting on a subduction zone or a fault line it is most likely that earthquakes will occur. Volcanoes usually occur where plates push up against one another and pushes through the crust creating a mountain like feature, then it is easy for the magma below the mantle to push up and create an active volcano.
because if there were no volcanoes in the world every thing would be water and we would not have any land.
Because that is where they plate tectonics collide and there is a hot spot underground.
When the big bang happened thousands and thousands of years old, the meteors that had crashed down made holes in the earth that we call today volcanoes.
Because they are closer to the earths crust.
Volcanoes appear on crevasses that let up magma that makes mountains with the lava, I think.
Volcanoes mostly occur in areas where tectonic plates meet. Most of the active volcanoes in the world occur in what is called the Ring of Fire around the edges of the Pacific Ocean.
The most volcanoes occur around the Pacific Ocean, in an area called the Ring of Fire.
Volcanoes occur near plate boudaries because volcanoes need water to erupt.
geosphere
The Island of Iceland has the most volcanoes (per area) of any place on Earth.
volcanoes can occur in any season
Yes they do occur under volcanoes
Earthquakes and volcanoes both occur in land and ocean. =)
No, hotspot volcanoes do not occur along subduction zones. They occur when plates pass over mantle hot spots.

Yes, they are likely to occur.
Volcanoes do not occur randomly over Earth's surface. They occur along the located mark of plate boundaries.

Yes and a great many of the earth's volcanoes are underwater.
