Water isn't just liquid, ice, or vapor — under extreme conditions, it can transform into exotic phases, such as the newly ...

Dry ice is a block of frozen carbon dioxide. It has a surface temperature of -109.3 degrees Fahrenheit, and if you place it in a bowl of warm water, then this accelerates the sublimation process.

Earlier this week we broke down the complexities of mixed-phase precipitation forecasting.Within that we briefly touched on a key component to that complexity w ...

Frost is what we call the white ice crystals we see on a cold day. It is formed when water vapour lands on a surface, like the pavement or grass, which is already below freezing. In the UK ...

The rare circular ice slabs spun, collided and collected in large eddies because of the prolonged cold weather.

The particles of ice would freeze the water, which would then fall back to Earth, removing excess water vapor and dehydrating the stratosphere where water turns into heat-trapping gas. The plan is ...

NASA's Rover found ripples in Martian rock that resemble the wave patterns on a sandy lake bed on Earth. The ripples could ...

ice, and a gaseous state, water vapor or steam. Water covers 71% of the Earth's surface. On Earth, it is found mostly in oceans and other large water bodies, with 1.6% of water below ground in ...
