After draining, lakes leave behind holes called ‘moulins’, which allow meltwater to continue to travel to the bottom of the ice sheet.

The world’s second-largest ice sheet, and the single largest contributor to global sea-level […]

Reconstructed paleo-elevation in southwestern North America at the Late Eocene (36 million years ago).

Scientists from NASA’s Mars 2020 and ESA’s ExoMars projects study stromatolites, the oldest confirmed fossilized lifeforms on Earth, in the Pilbara region of North West Australia. The image was taken on Aug. 19, 2019. Credit: NASA/JPL-Caltech As any geologist worth his or her salt will tell you, there are rocks, […]

Boston College Professor of Earth and Environmental Sciences Ethan Baxter, at work on Greek island of Sifnos. Analysis of garnet samples collected on the island confirmed theories that water flowing from deep in the Earth millions of years ago is the source of oxidation found in the remnants of ancient […]

Did an extraterrestrial impact trigger the extinction of ice-age animals? University of South Carolina archaeologist finds evidence in South Carolina to support controversial theory. A controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population […]

How vulnerable are landmark stone formations to tremors from earthquakes or human activities? The researchers’ analysis showed two strong, distinct peaks in the data at 0.8 and 1.0 Hz. Those resonant frequencies make the structure vulnerable to strong-magnitude earthquakes. Smaller quakes—or minor vibrations from traffic, construction machinery, or other environmental […]

Lava from a fountain on Hawaii’s Kilauea volcano flows over a spillway into an established channel in June 2018. (Image courtesy of U.S. Geological Survey) Tool lets scientists examine changing behavior of low-viscosity lava. Thomas Jones’ “universal break-up criterion” won’t help with meltdowns of the heart, but it will help […]
