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 ...

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 ...

The bulk elemental composition of Earth can’t be fully explained by compositional differences in its initial building blocks, according to a new study by Paul Frossard and colleagues. Instead, they ...

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 ...

Understanding Earth's Crust Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

IT TURNS out there’s a lot we don’t know about our planet — and a new understanding is said to have “far-reaching importance” for our future. If so, you’re in good company because it was also somewhat ...

Scientists have made significant progress in drilling into the Earth’s crust, reaching unprecedented depths that bring them tantalizingly close to the mantle. This monumental feat aims to unlock ...

Scientists at the University of Southampton have discovered that the evolution of land plants caused a sudden shift in the composition of Earth’s continents. The Southampton researchers, led by Dr Tom ...
