An International team of scientists finds evidence that Earth began recycling itself more than 3 billion years ago.
Here’s one explanation for why Earth’s magnetic field undergoes weird geomagnetic jerks every decade or so.
A slippery layer beneath Earth stops chunks of crust in their tracks, creating "stagnant slabs" in the middle of the mantle.
Rocks from the eastern shore of the Hudson Bay in Canada contain elements of some of Earth's earliest crust, new research finds.
The Earth's mantle retains traces of primeval materials that are older than the moon, which formed a scant 100 million years after the solar system's coalescence.
Scientists trying to determine where the missing heat from the Earth comes from have turned to an unlikely source: a microwave oven.
Researchers have found that the vast majority of brimstone — reverently referred to in biblical times as "burning stone," but now known more commonly as sulfur — dwells deep in the Earth's core.
New research claims to have solved a messy paradox that has plagued geoscientists who study Earth's core and its life-protecting magnetic field.
Continents move, but what got them going? A new computer model shows it was gravity. Whole continents flattened out under their own weight.
A battered diamond that survived a trip from "hell" confirms a long-held theory: Earth's mantle holds an ocean's worth of water.
Researchers recently discovered a new crystal defect in olivine that helps explain how the mantle drives plate tectonics.
