Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

BUFFALO, N.Y. — At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from ...

Far beneath the Atlantic Ocean, about 1,000 kilometers off Portugal’s coast, lies a colossal underwater canyon system that dwarfs even the Grand Canyon. Known as the King’s Trough Complex, this ...

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for over 160 million years. Known as Pontus, this tectonic giant once covered ...

A unique rock formation in China holds clues that tectonic plates subducted, or went underneath other plates, during the Archean eon (4 billion to 2.5 billion years ago), just as they do nowadays, a ...

At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force ...
