Evidence from the Pilbara region suggests Earth in its youth behaved very differently to how it does today, and had more water within it than previously thought.
Earth's magnetic field locks information into lava as it cools into rock. Millions of years later, scientists can decipher this magnetic data to build geologic timelines and maps.
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.
Giant forces slowly move continents across a viscous layer of the Earth, like biscuits gliding over a warm toffee ocean. This stresses the continents, and twists and contorts the crust.
Scientists have used gravitational measurements from the low-flying Goce satellite to map the boundary between the earth’s…
