What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

WASHINGTON (Reuters) - Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and ...

Deep below Earth's surface lie two gigantic structures with mysterious origins. Now, seismologists have found new clues about their composition that could upend our understanding of the whole planet's ...

It is easy to see that the processes in the Earth's interior influence what happens on the surface. For example, volcanoes unearth magmatic rocks and emit gases into the atmosphere, and thus influence ...

It’s widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the sun, gathering in rocky clumps to form ...

Earth's mantle is the thick layer of silicate rock between Earth's crust and its molten core, making up about 84% of our planet's volume. The mantle is predominantly solid but, on geologic time scales ...

Scientists mapping how seismic energy travels through Earth's mantle discovered two structures beneath Africa and the Pacific that rise up to 1,000 kilometers from the core-mantle boundary, roughly ...
