Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
The Earth’s crust is constantly rewritten by volcanoes, erosion, and plate tectonics. New crust is being created while old ...
Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...
Scientists used a new technique to estimate the abundance of hydrogen in Earth’s core. - Tumeggy/Science Photo Library RF/Getty Images Picture all of Earth’s oceans, which cover about 70% of the ...
Earth's core: solid or liquid? Yes — we know more about distant galaxies than our own interior. Is Earth's core solid or liquid? Yes. Our planet's interior has been harder to study than the cosmos. We ...

Seismic studies from Antarctica suggest a widespread layer of ancient ocean floor may coat the core-mantle boundary, while other research identifies a distinct zone deep within the solid inner core.
Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...
