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 ...

Scientists believe that Earth's core is a massive ball of iron. However, a new discovery suggests that the Earth's core is surrounded by an unexpected ancient structure. A high-resolution map of the ...

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed ...

So much is made of scientific discoveries in outer space, as we try to broaden our horizons and explore the surface of Mars, but in reality, many of us don’t know much about things right below our ...

Scientists have discovered that the evolution of land plants caused a sudden shift in the composition of Earth's continents. Scientists at the University of Southampton have discovered that the ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

The internal structure of Earth, structure of the solid Earth, or simply structure of Earth refers to concentric spherical layers subdividing the Solid earth, i.e., excluding Earth's atmosphere and ...
