How does water vapor condenses in the atmosphere?

Answer 1

The air itself cools to below the dewpoint. But there actually are surfaces in the sky, very small ones such as dust and salt particles. They are critical to droplet formation. Without them, the moist air would have a very hard time condensing the water out. It would have to be cooled to well below the dewpoint before enough water molecules could get together to form a droplet. But once it did that would be a sight because that highly subcooled droplet would suddenly be the surface that all the water would condense on, and it would get real big, real fast.

Answer 2

Yes. Water vapour is water in its gaseous state. When it reaches the sky (which is very cold), it condenses into very tiny water droplets that float high up in the sky and also joins up with other tiny water droplets to forms clouds. When the tiny water droplets merge in to a bigger one, it gets heavier which causes the cloud to fall (rain)

Answer 3

First the sun causes water to heat up, causing molecules to spread out and become water vapor. As the vapor rises higher into the atmosphere the temperatures drop and the water molecules move closer together, condensing into water.

Answer 4

Yes, water vapor condenses into droplets to form clouds. Though in some higher-altitude clouds the water vapor transitions directly into ice crystals.

Answer 5

So it can rain!
