Geoscientists from the University of Toronto have made a breakthrough discovery that adds new dimensions to the theory of ...

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 ...

Our understanding of our own planet is still changing and a relatively new theory about how plate tectonics works.

This volcanic arc delineates the boundary between the Pacific and North ... This zone marks the interface where the denser Pacific oceanic plate subducts beneath the less dense continental North ...

It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of ...

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 ...

Researchers have discovered that the underside of the North American continent is dripping away in blobs of rock—and that the remnants of a tectonic plate sinking in Earth's mantle may be the ...
