What are clouds? Clouds Clouds are the collection of millions of water droplets or ice crystals that have condensed and saturated tiny particles in the air. Warm air rises (while holding water vapor) and then cools. When the air cools the water vapor or gas condensates into a liquid. Sometimes the water vapor freezes to become tiny ice crystals. Clouds are named by form and altitude. Cumulus These clouds are puffy and white. They have a flat bottom and can sometimes look like piles of cotton balls. Thunderstorms form from a type of Cumulus cloud called Cumulonimbus. These clouds are tall and strong. Stratus These clouds form in layers. They are flat and thin. They cover large areas of the sky. They resemble blankets. Fog is a stratus cloud that has formed near the ground. Cirrus Cirrus clouds are thin, feathery white clouds that form at high altitudes. They are wispy. They form when the wind is strong. They are at the highest altitude. If they get thicker, a change in the weather is about to occur. Why do they make rain? When those water droplets and ice crystals get too heavy, the cloud “empties” the precipitation out. It may not always be liquid water that falls…hints snow and sleet. Project Over the next 20 days, I want you to log what types of clouds you see. You will include information such as what cloud type exists ( at 2 separate times during the day), the temperature at the time you logged and what weather event was occuring: ex. Sunshine, rain, fog. This will be a 200 point project. I will give you a rubric so that you will know what is expected. NO EXCUSES!!! This will be due to me March 25, 2011. There will be an opportunity for 15 points extra credit for an analysis and presentation of your findings. Good luck.
