Roughly 40% of the Earth’s total heat flow is powered by radioactive decays in the crust and mantle. Geo-neutrinos produced by these decays provide important clues about the origin, formation ...

In this lesson, students learn why, where, and how earthquakes happen. Students are introduced to the interior structure of the Earth and plate tectonics. Plate tectonics is the engine behind the ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

A large sub-Neptune-sized planet revolving around a red dwarf star 124 light years away has been the topic of debate among ...

However, the enormous thermal energy emanating from the Earth’s interior set dynamic processes in motion, such as mantle convection, plate tectonics and volcanism. Still unanswered, though, are the ...

Earth has multiple layers: the crust, the mantle, the liquid outer core and the solid inner core. (Image credit: NASA) Earth's interior is made up of a series of layers that sit below the surface ...

Officials are warning people to stay away from beaches and waterways in a small California city near the border with Oregon ...

Examining how plates move in Earth's mantle and how mountains form is no easy feat. Certain rocks that have sunk deep into Earth's interior and then returned from there can deliver answers.

Earth’s interior is cooling faster than expected Date: January 14, 2022 Source: ETH Zurich Summary: Researchers have demonstrated in the lab how well a mineral common at the boundary between the ...

The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma.

Earth's deepest ocean The diamond from Brazil confirms that the models are correct: Olivine is ringwoodite at this depth, a layer called the mantle transition zone.
