Why are are volcanoes located near plate boundaries?

Answer 1

Because fault lines are cracks in or spaces between the Earth's tectonic plates that make up the crust (outer layer), and they sometimes move around or over each other, and that makes the earth shake.

Answer 2

These faults are normal(divergent), reverse(convergent), or strike slip(subduction or transform). Divergent causes rock to spread out and rise. Convergent causes the rock to be compressed into a hill, and transform faults(strike slip) go underneath one another which causes the ground to shake.

Answer 3

cuz lava comes out and it forms it around the volcando



because At Fault lines/boundaries sometimes the continental bounderies both push together(some pull apart) it form mountains and if the magma travels up the mountain per se it either erupts or melts away the top hence volcanoes being formed.


in short because the continental boundaries are pushing together

Answer 4

Many volcanoes form near plate boundaries where oceanic crust collide. Through subduction, the older, denser plate sinks beneath a deep-ocean trench into the mantle. Some of the rock above the subduction plate melts and forms magma. Because the magma is less dense then the surrounding rock, it rises toward the surface. Eventually, the magma breaks through the ocean floor, creating volcanoes.

ADDED:

It's more common where oceanic plate meets continental plate. The ocean plate is subducted below the continent, and the trench marks the flexure of the subducting plate. It is not above the subduction as the answer above suggests. Also, most of the melting is of the sinking plate, not the upper one, though that contributes to the magma too.

Answer 5

Volcano's are located near plate boundaries because that's how volcano's are created. Volcano's are created by the subduction of two plates, the plate that goes up creates a mountain and the plate that goes under can sometimes enter into the mantle and so it melts turning into magma. The magma then gets pushed up through the plates and shoots up through the plate that went up, making it a volcano.

Answer 6

Earthquakes occur along faults when two or more tectonic plates shift. They can move past each other or one can move under another. Both of those cause earthquakes.
