What is Weather?
[]

1. Define weather.:**This is the layer which is closest to the earth's surface, or the actual sky that we can see. ** 2. What four factors affect weather:** Air in the atmosphere is sinking and pressure of the atmosphere is higher at the surface.Similar to the leading edge of army soldiers moving forward along the //front line//, the leading edge of an air mass moves forward along a weather front. **

Weather vs Climate

3. What is the difference between climate and weather? There is a variety of ways to explain the difference. Here are a few that may shed some light.

** 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 ** 3. What are the 3 "families" of clouds and what do their Latin names mean?** of clouds: cirrus, cumulus, and stratus. These are the latin names given to clouds in 1804 ** 4. Follow the links to learn about each type of cloud and then complete the table on the next page. To help you identify clouds, download, print and construct the following "Cloud Key".

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || Cirrus clouds are thin and wispy, and are found very high in the sky. || thin and wispy, and are found very high in the sky. Cirrus clouds point in the direction the wind is blowing. No precipitation falls from cirrus clouds. ||
 * altocumulus || These clouds are like fuzzy bubbles in long rows or strings. || it usually means that a cold front is coming. If it's summertime and warm and humid, altocumulus clouds may turn into thunderstorms when the cold front approaches. ||
 * nimbostratus || These clouds are dark and low-hanging clouds that cover the whole sky || They bring with them light to moderate precipitation. ||
 * cumulus || These clouds look like big cotton balls in the sky. || Normally they don't carry any rain, but during the spring and summer they can change into cumulonimbus clouds. ||
 * cumulonimbus || They are tall and wide clouds that have heavy rain, thunder || If you see these clouds on the horizon, it is likely it will rain very soon. ||
