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 ...

For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

Planetary scientists at ETH Zurich have shown that the material that makes up the Earth originates exclusively from the inner ...

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 ...

Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner ...

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.

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 ...
