There are actually two North Poles. One has been wandering over northern Canada and north of there for years. An earth scientist explains why and what it means for holiday travel.
The Earth’s inner core has long been a total mystery.
Volcanoes and earthquakes are both natural phenomena driven by the dynamic processes that shape Earth’s interior and surface.
The Earth’s core may be much younger than previously thought.
Like a piece of music, every earthquake has a coda – and it contains clues about what’s happening in our planet’s core.
The Moon was formed when it collided with Earth billions of years ago.
Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.
A distant lump of space rock may have a surprising amount in common with the core of our own planet.
Liftoff to the distant asteroid is scheduled for Oct. 5, 2023 – the beginning of a six-year journey to one of the most unusual objects in the solar system.
Scientists were not previously certain how the precious stones arrived at the Earth’s surface.
The Earth isn’t permanent, but it was here for four billion years before humans arrived and should be here for several billion more.
Earth doesn’t just have an inner core. It also has an innermost inner core, a solid ball within the solid ball in the very middle of the planet.
Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.
Could tectonic processes in the early Earth have contributed to the rise of oxygen?
Geology experts explain why coloured diamonds are so much rarer than clear ones – and why the newly discovered Lulo Rose might become the most expensive diamond in history.
This is a really important question, and one which climatologists work on in many aspects of their jobs.
8,000 tonnes of molten iron solidifies in Earth’s inner core every second – but it’s not distributed equally.
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.
The updated methods are providing a clearer picture of how Earth and its inhabitants evolved over the past 60,000 years - and thus, providing new insight into its future.
