Changes in the Earth’s magnetic field pose a great risk to electronic infrastructure.
Of all the planets in the solar system, there’s a reason we call Earth home. It’s made of just the right stuff. It’s not too small, or too big, or too hot or too cold. It’s just right.
Fossil fuels are heating the atmosphere – but the fact that we’re burning them may not be the only reason.
New findings suggest the core has been leaking for the past 2.5 billion years, and that could help scientists understand how the core was formed.
The Earth’s core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
A strange patch of extremely strong magnetic field occurred over Jordan in 1000BC. Could we be about to face another one?
Signals from violent earthquakes are helping reveal the landscape of the planet’s insides.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
The Earth’s inner core is more than half a billion years older than previously thought, shows a study. The results could help us better understand the processes that shape the planet’s surface.
The discovery of a thickly viscous layer which traps sinking plates below Earth’s surface has wide implications, not least as a cause of earthquakes.
The planet Earth’s inner core is not a single solid mass but comprised of two layers, and new evidence about the core’s composition from a team of US and Chinese geophysicists suggests that the innermost…
Our planet’s interior is complex and has many layers. Their formation and structure contain many unsolved mysteries. But new research is providing some clues about how Earth’s internal structure may have…
