Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...

An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state. This ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...

Reservoirs of hydrogen gas that form naturally in Earth's crust could help humans decarbonize. The challenge now is finding these accumulations and working out how best to mine them, experts say. When ...

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet’s magma creates continents – and may have even helped create life. In ...

Unraveling the mysteries of our planet, scientists have recently discovered the fate of a large chunk of Earth’s crust that has been missing for millions of years. It turns out that the crust was ...
