The answer is subduction ... where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth.

These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts up, it also forms mountain ranges. In addition ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

The Cascadia subduction zone, where the oceanic Juan ... Figure 4: Schematic cross-section of the northern Cascadia convergent margin at southern Vancouver Island. The plate boundary forms a thick ...

It also provides new ways to explore when plate tectonics began, how subduction dynamics operated ... melting of subducted oceanic crust beneath convergent continental margins," said Keller ...

The answer is subduction ... where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth.

This is called a destructive or convergent plate boundary. When the plates collide, the denser plate, usually the oceanic one, is forced underneath the continental plate. The force of this ...
