In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

The Earth's oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the ...

Comparing the thickness of oceanic crust of different ages, Van Avendonk and colleagues discovered that 170-million-year-old crust is 1.7 kilometers thicker on average than fresh crust.

The crust is what you and I live on and is by far the thinnest of the layers of earth. The thickness varies depending on where you are on earth, with oceanic crust being 5-10 km and continental ...

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 ...

Beneath its surface, scientists found an unexpectedly thick and dense structure ... Scientists have long believed that ...

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

Continents and oceans have scientific definitions that underpin international law. The idea of dividing the world into geographical zones is ancient. Sovereignty and influence over natural resources ...

New estimates of the thickness of the crust of Antarctica have been made with seismic data showing the ... or mountains formed when a continental tectonic plate slides over an oceanic plate. ...

Francesco Bianchini, librarian to Pope Alexander VIII, drew the first map of Venus in 1726. Too bad he got it all wrong. Using a 150-foot-long telescope, he outlined oceans and continents. But he w… ...

Much Antarctic research focuses on ice — and rightfully so, since a giant ice cap up to 2,361 miles (3,800 meters) thick covers about 99 percent of the continent. But under that layer of frozen ...

The Earth's crust has a dual personality.On one hand, there are the continents. Many times, the crust that makes up the continents can be very old, upwards of 3 to 4 billion years old!Yet, the oceanic ...
