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 ...

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to ...

The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, ...

The thickness varies depending on where you are on earth, with oceanic crust being 5-10 km and continental mountain ranges being up to 30-45 km thick. Thin oceanic crust is denser than the thicker ...

Earth's middle layer is chunky, like peanuts in a sea of caramel. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In Geology 101, Earth's ...

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 ...

Miles beneath the sea surface, buried beneath the seafloor sediment, a relatively unstudied ecosystem of bacteria and other microbes teems with activity in the Earth's oceanic crust. Some ...

This is why Earth's continents are known to be several billion years old, while the oldest oceanic crust only dates back 165 million years" said Mohamed Mezouar, scientist at the ESRF.

Parts of earth's crust are constantly pushed and dragged into the interior, melting there. New crust forms along the sutures of earth's plates. That's why the oldest oceanic crust dates back only ...

Most oceanic crust is less than 200 million years old, because it is typically recycled back into the Earth's mantle at subduction zones (where two tectonic plates collide).But a new study shows ...

The early Earth was a very different place. Go back 4 billion years and the Earth's surface was mostly basalt -- the stuff of oceanic crust.After the formation of the planet (and the subsequent ...

In Geology 101, Earth's interior is divided into neat layers, like a sugar-coated jawbreaker. But it turns out that parts of the planet's middle layer might be more like peanuts in a sea of caramel.
