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 ...

Plate tectonics is geology’s Theory of Everything. The realisation in the 1960s that Earth’s crust is made of fragments called plates—and that these plates can grow, shrink and move around—explained ...

An ocean that opened up in what is now Mongolia 410 million years ago was created by a hot upwelling of rock known as a mantle plume. When you purchase through links on our site, we may earn an ...

The Sentry, an autonomous undersea vehicle, was used to map the magnetic stripes in Pito Deep, a large chasm in the Pacific Ocean that provides a cross-section of samples of lower oceanic crust.

Recent scientific investigations have revealed that a significant portion of Earth’s crust has disappeared over millions of years, primarily due to extensive erosion. This discovery has shed light on ...

The thick outer crust of Earth has zillions of wafer-like pieces interlocked and held together like a cork trapping the molten hot mantle. The blizzard-like forces agitating inside the mantle continue ...
