Inch by inch, as massive glaciers crept over frozen land toward an ice-covered sea, they scoured the ground beneath them, ...

Traces of these events can be seen across the globe in sedimentary rocks formed under glacial conditions, strongly suggesting that ice spread from the poles to reach the equatorial region. Nobody is ...

These rocks preserve a detailed record of sedimentation during the Neoproterozoic, including distinct layers deposited during three major glacial episodes: the Sturtian (717-658 million years ago), ...

Researchers did not expect the huge size of the meteorite given the frigid continent's history of thousands of space rocks ...

Scientists reveal glaciers may have scraped away miles of Earth's crust during 'Snowball Earth,' erasing a billion years of ...

A new study suggests glaciers carved metals out from the Earth’s surface 700 million years ago, leading to chemical reactions ...

The planet experienced at least two "extreme global glaciations" during the Cryogenian period, traces of which can be ...

Research indicates that delicate deepwater corals tolerated or adapted to major climate and salinity fluxes, “yet today, it’s ...

As glacial ice moves very slowly downhill, pieces of rock and gravel get stuck between the ice and the land, forming a coarse surface, similar to the sand on sandpaper. These rocks grind together ...

As Colorado enters its snowiest month, it may be wise to find trails at slightly lower elevations within Rocky Mountain National Park to avoid dangerous avalanche conditions in the higher reaches ...

Inch by inch, as massive glaciers crept over frozen land toward an ice-covered sea, they scoured the ground beneath them, gouging and scraping rocks from Earth’s crust. When the glaciers ...
