A massive ice sheet once covered much of Canada and the northern U.S., causing land shifts as it melted. New research shows ...

It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Insulation provided by carbon dioxide ice above the martian polar caps could explain many of the Red Planet’s ancient river features.

New research suggests that about 3.6 billion years ago, Mars featured vast water flows and a lake rivaling the size of the ...

Heat emanating from Mars’s still active interior was insulated by the carbon dioxide ice, warming up the water ice causing about half of it to melt and flow across the Red Planet’s ancient surface.

A new study suggests that the planet’s icy interior and liquid ocean could be insulated with a three-to-six-mile-thick layer ...

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results provide the first direct geochemical evidence of the ...

Old or new, sedimentary or igneous, some of the Earth's crust drifts below the surface at subduction zones, where one continental plate overlaps another. When it does, some of it melts, eventually ...

If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31.

Florida State University Assistant Professor of Geology, Emily Stewart, has conducted new research that questions the ...

On a cold, ancient Mars, rivers flowed and a lake the size of the Mediterranean Sea swelled under the protection of thick ice ...
