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 ...

Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

The Earth’s oceans have risen and fallen over the millennia. But they have, on average, been relatively stable over billions of years. The balance of the deep water cycle—the exchange of water between ...

Waves in Earth's mantle created by the rifting of continents may peel the planet's crust from below, feeding volcanoes in the middle of the ocean.

At an underwater mountain in the middle of the Atlantic Ocean, scientists have drilled nearly a mile beneath the ocean floor and pulled up an unprecedented scientific bounty — pieces of Earth’s rocky ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Strange features of a collision point between pieces of Earth's crust are evidence that the structure may be nearing its end, new analysis suggests. A careful analysis of the complex boundary where ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

Scientists discovered a crack under the sea off Vancouver Island, NFZ in Cascadia region, that could alter Pacific subduction ...
