Earth's gold reservoir, deep beneath the surface, leaks precious metals through volcanic eruptions. New research shows how volcanic rocks carry gold and other metals from the core to the surface.

But we can't: The precious metal lies more than 18,000 miles below the surface. It's up to Earth, then, to dish out its gold reserves as it sees fit—a process that is slowly and surely on its way.

Earth's Surface. The Secrets of How ... to a remote site in northern Canada to collect four-billion-year-old rock samples that could unlock mysteries about Earth’s earliest history. May 16, 2025.

Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning faster than the planet's surface and might now be rotating slower than it, research suggested on Monday.

Changes in the sea surface height therefore point to what lies deep beneath the surface. The team focused on three types of underwater features: abyssal hills, small seamounts and continental margins.

Researchers from the Goethe University in Frankfurt have analyzed a rare diamond that formed 660 kilometers (410.1 miles) below the Earth's surface and was sourced from Botswana, Africa.

Those "arteries" are the various oceans, bays, rivers, lakes and reservoirs that make up all water on Earth's surface. SWOT will circle the globe at an altitude of about 500 miles, traveling over ...

The formation of new enigmatic layer – E prime layer – at the outermost part of Earth's core is a result of "surface water penetrating deep into the planet," altering the composition of the ...

Scientists have discovered a previously unknown layer of Earth. The newly discovered region of molten rock sits 100 miles below the crust and covers at least 44 percent of the planet.
