The oceanic crust produced by the Earth today is significantly thinner than crust made 170 million years ago during the time of the supercontinent Pangea.

A new study confirms a major feature in the formation of large igneous provinces -- massive worldwide volcanic eruptions that triggered mass extinctions from 170 to 90 million years ago.

Understanding how carbon dissolves in water at the molecular level under extreme conditions is critical to understanding the Earth’s deep carbon cycle—a process that ultimately influences global climate change.

Life took hold on land at least as early as 3.2 billion years ago, according to a new study published in the journal Geology.

A new study shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen — a finding that suggests similar seismic activity on Mars may produce enough hydrogen to support life.

With three new detectors coming online in the next several years, scientists are confident they will collect enough geoneutrino data to measure Earth's fuel level.

A new study suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and a Mercury-like planet.

New clues challenge a long-held notion of what moves what deep under the sea.

Bombardment triggered atmospheric warming capable of sustaining liquid water.

New work sheds light on the history of Earth's magnetic field, an incredibly important geologic occurrence without which life as we know it would not exist.
