Arizona State University researchers say they have discovered a large cylindrical blob of cold material far below the surface of central Nevada. Led by geologist John West, the scientists determined the blob was formed when portions of the lithosphere -- the Earth's crust and uppermost mantle -- had sunk into the more fluid upper mantle beneath the U.S.

The Dead Sea lies in a basin structure situated below the sea level. This deep subsidence is a result of a tectonic concurrence between processes in the upper lithosphere that led to subsiding and a compensating upward flow of rocks in the deeper layers of the lithosphere.

A strip of bedrock located in the eastern area of Canada's Hudson Bay was discovered to have the oldest rocks on Earth, said scientists on Thursday. The rocks were formed about 4.28 billion years ago, shortly after the planet was created. It might even contain evidence of movement by ancient creatures.

A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place.
