What is subduction and what does it cause?
What causes subduction? Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth’s interior. Not all convergence leads to subduction. Continental rocks are too buoyant to be forced downward, so when continents collide, they crumple but stay at the surface.
What is subduction and where does it happen?
Subduction is a kind of geological recycling that occurs at convergent plate boundaries, where two tectonic plates come together due to the motion of the fluid mantle layer of the earth.
What is subduction and evidence for it?
There’s lots of evidence that subduction occurs, primarily the fact that we can see it occurring using seismic tomography, a technique that uses computational methods and lots of maths to figure our the paths that P and S waves take through the Earth, what material they’re travelling through and how how the material is, for example.
Why does the subduction occur?
Why do subducting plates occur? Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth’s interior. … When an oceanic plate collides with a continental plate, the denser oceanic plate is bent downward and slides under the edge of the continent.
