An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.
