Earth's Interior

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.
