In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge ...

The crusty conundrum carries fundamental implications. The thickness of continental crust — the part of Earth’s crust that forms land masses and continents — plays an important role in everything from ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...
