Most of Earth's mantle is hot but solid, with rocks that deform slowly rather than cracking like the cooler rocks of the crust do. But new research finds that around 93 miles (150 kilometers) below ...

New Curtin University research on the remixing of Earth’s stratified deep interior suggests that global plate tectonic processes, which played a pivotal role in the existence of life on Earth, started ...

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 ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

The Earth's crust is composed of approximately 15 to 20 tectonic plates, which float on molten magma beneath the Earth.
