The most high-resolution map yet reveals something we previously never knew about: an ancient ocean floor that may wrap around the core. This thin but dense layer exists around 2,900 kilometers below the surface.
U.S. recent study revealed a layer between the Earth's core and the mantle that is likely a dense, yet thin, sunk ocean floor.
The new layer of the inner core consists of an iron-nickel alloy, like other parts of the core, but it has a different crystal structure.
Chinese scientists say that based on their calculations, a small imbalance in the electromagnetic and gravitational forces could slow and even reverse the inner core’s rotation.
The length of our day changes slightly over a six-year period. This recent discovery has perplexed scientists for about a decade and now we know the reason for it - it is the Earth core.
The enhanced growth on one side of the core suggests that something in Earth’s outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil.
Recent study shows that beneath the Yellowstone volcano lies a so-called mantle plume: a chimney-like structure that reaches thousands of kilometres deep to the border of the Earth's core and mantle.
Satellite observations of the Earth's magnetic field reveal a fast-moving stream of metal deep inside the planet.
