Earth's crust is the planet's outermost layer. It is made of solid rock and sits on top of another layer, called the mantle. The mantle flows and stretches like bubble gum, while the crust above ...

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 ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began.

For over a century, scientists puzzled over why huge parts of Earth's crust were missing—now, they believe ancient glaciers may have scraped it away during a global freeze. New studies reveal up ...
