The deep oceans are far from flat. They feature ridges, trenches, seamounts, and valleys, creating a diverse and dramatic ...

divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed; collisional boundaries, where two land masses collide; and transform boundaries, where two plates ...

(This includes the crust and uppermost part of the mantle ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...

Or the crust can crack open enough to let melted rock from the next layer of Earth, the mantle, rise to the surface. One place this happens is at the boundaries of tectonic plates, which are the ...

At divergent boundaries, plates move away from each other ... Analysis of the data reveals five zones of low resistivity in the underlying crust and mantle, indicative of the presence of fluids.

The north pole of Mars is slowly sinking under the weight of an ice cap that only formed within the past few million years. And, in the process, it's telling us something about what the planet's ...

Fold Mountains, such as the Andes, are also found at destructive plate boundaries. They are formed due to the pressure of the two plates colliding, which forces the continental crust to crumple ...
