What is Weather?
[]

1. Define weather. ** The WEATHER is the condition of the atmosphere (or changes in the atmosphere) at a particular time and place. ** 2. What four factors affect weather
 * ** the air **
 * ** the sun **
 * ** water **
 * ** the earth's movement **

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. It tells us the average or most common conditions, or extremes, or counts of events, or frequencies. **Weather** is a description of conditions over a short period of time - a "snap shot" of the atmosphere at a particular time.

If **weather** is the watch then **climate** is the calendar

** 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 major part of our weather. ** 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? ** There are three families of clouds: cirrus, cumulus, and stratus. These are the latin names given to clouds in 1804. Cirrus means 'curl of hair', cumulus means 'heap', and stratus means 'layer' ** 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". [] After completing the chart, you could try a Cloud Quiz at; []

**Warm and Cold Fronts **
|| **Understanding Basic Concepts** - explain the difference between warm and cold fronts and the factors that influence both of these systems - identify types of weather associated with each front || []

[]

Write the capital letter A or B at the end each sentence. A = Cold Front B = Warm Front 1. Cool air mass - warm air mass moves in. B 2. Warm air mass - cool air mass moves in. A 3. Brings gentle rains that may last for hours or days. B 4. Strong winds are formed followed by heavy rain, crashing thunder, and flashing lightning. A 5. When the front passes, the temperature warms up and it becomes humid. A 6. When the front passes, the weather turns cooler. B 7. Farmer Brown prefers this type of front. B 8. Usually happens and is over with quickly. A
