The World Ocean, which is all the oceans taken together, covers a total of 139,782,000 square miles (363,433,200 square kilometers)—about 70.8 percent of the Earth's surface. Over 200,000,000 years ago, the World Ocean was one body of...

The continental crust is the layer of granitic, sedimentary, and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. Consisting mostly of sialic rock, it is less dense than the...

The influence of pre-existing structural anisotropy on faulting in the continents is best tested in recently exhumed crust (e.g. Nanga Parbat Massif, NW Himalayas), where earlier brittle structures have been annealed. The kinematics of young faults, formed in a single, continuing tectonic regime (NNW...

Microscopic diamonds found in southwestern Norway challenge the established theory that diamonds are formed only in the Earth's mantle. One explanation is that portions of crusts were pushed down into the mantle temporarily by continental collisions. A prevailing theory has not yet been found....

If it weren't for the hot rocks down below Earth's crust, most of North America would be below sea level, report researchers who say the significance of Earth's internal heat has been overlooked.Without it, mile-high Denver would be 727 feet below sea level, the scientists...
