When water vapor cools sufficiently, it condenses into water droplets. Think of a cold can of soda on a hot day: water droplets appear on the outside because the thin layer of air surrounding the ...

When a front moves through or on just a regular day we can see middle tiered clouds here at home. Altocumulus clouds ...

They use the sun’s heat to evaporate water, leaving salt, bacteria and dirt behind. Then, the water vapor cools and returns to a liquid state, at which point it’s collected in a clean container. The ...

Heat also changes liquid water to water vapor (evaporation). As it cools, water vapor becomes liquid again (condensation). As it cools even more, liquid water becomes ice (freezing). Water molecules ...

This process is called evaporation. When the water evaporates, it leaves everything else in it behind. When the water vapor cools, it becomes liquid water again. This process is condensation. There’s ...

Atmospheric rivers are long and relatively narrow bands of water vapor that form over an ocean and flow through the sky, ...

This rises into the air. Cloud formation: The water vapor rises into the sky, where it’s colder. There, the vapor cools and turns back into small water droplets. These droplets gather and form clouds.

As the water vapor moves inland, it rises over mountain ranges, condenses, cools, and falls as heavy precipitation. In the valleys, this can result in several inches of rain, creating flash floods ...

When the moisture-laden air moves over mountain ranges such as the Sierra Nevada along the California-Nevada line, the water vapor rises and cools, becoming heavy precipitation that falls as rain ...
