Weather vs Climate
__ [] __

3. What is the difference between climate and weather? Climate is what you expect; Weather is what you get. Climate is about long-term records, trends and averages. Weather is the day to day experience. Climate is the sum or synthesis of all the weather recorded over a long period of time .

 * The following web site describes some of the instruments meteorologists use to collect data about the weather. **

Use the information to complete the chart. The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.

** Clouds **
|| **Understanding Basic Concepts** - explain the formation of clouds and the effects of different cloud formations on weather and climate ||


 * Use this web site to answer the following questions. **
 * []**

1. What are clouds? Clouds are a visible mist of billions of water and ice particles floating in the sky. 2. Explain how clouds form. Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. The water droplets then form a cloud 3 . What are the 3 "families" of clouds and what do their Latin names mean? 4. Follow the links to learn about each type of cloud and then complete the table.


 * **Cloud Type** || **Description** || **Possible Weather** ||
 * Cirrus || wisp of curls || rain ||
 * Altocumulus || broken into bands, blobs, rolls, or waves || rain or snow ||
 * Nimbostratus || spread out, color sky gray || rain and snow ||
 * Cumulus || cottonballs || can cause rain, but not always ||
 * Cumulonimbus || puffy and dark || rainshowers, snow showers, hail or a thunderstorm ||
