The deep part of Earth's middle layer is on the move. New research finds that the lower mantle, located between 410 miles and 621 miles (660 and 1,000 kilometers) beneath the Earth's crust, is ...

When continents collide, they buckle upwards and sideways to form mountain ranges: the Himalayas, for example. When continental and oceanic regions collide, the oceanic crust slides beneath the ...

Continental crust is also much less dense than its oceanic counterpart. In 1962, famed Princeton geologist Harry Hess theorized that the thickness of continental crust had to do with sea level and ...
