The temperature at which water vapor in the air condenses, or turns to liquid, is called the dew point. There is no single dew point however. It depends on how much water vapor is in the air. If there is a lot of water in the air, the dew point is a high temperature. If the air is dry, the dew point is a low temperature. Once the dew point is reached up in the sky, it causes clouds, rain, snow, and other precipitation. If it happens near the ground, condensation causes dew, frost, or fog. Either way, it’s a wild and wet time when the dew point and temperature meet. For more information on the dew point, see the Rain and Snow issue of Kids Discover magazine.
