What is Weather?
[]

1. Define weather.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.

Air Pressure
__ [] __ 4. Complete the following chart:

up || warm || .cold ||
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || .down || .
 * Temperature of air ||.
 * Wind movement at ground || . clockwise || . counterclockwise ||
 * Expected weather || .bad || .good ||

** Measuring the Weather **
|| **Developing Skills of Inquiry, Design and Communication** - design, construct, and test a variety of weather instruments - use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations ||

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

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. 3. What are the 3 "families" of clouds and what do their Latin names mean? cirrus, cumulus, and stratusCirrus 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".

Cloud Forecasting

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || "Cirrus" in latin means curl and these clouds are named because they resemble wisps of curly hair || They are often a sign that it is going to rain. ||
 * altocumulus || Altocumulus clouds consist of a thin sheet of white or gray clouds that are broken into bands, blobs, rolls or waves.The name altocumulus means middle height and heap || They bring a sign of rain and snow ||
 * nimbostratus || The word Nimbostratus means "rainstorm" and "spread out" in Latin. || Rain and snow often accompany the development of nimbostratus clouds. ||
 * cumulus || Cumulus clouds are puffy, low altitude clouds. These clouds often resemble cotton balls. || Cumulus clouds can cause rain, although rain does not always follow cumulus clouds. ||
 * cumulonimbus || These clouds are named because they are puffy ("cumulo") and because they often are dark clouds which cause rainstorms ("nimbus"). || Cumulonimbus clouds can produce rain showers, snow showers, hail, or even thunderstorms. ||

**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 .A 4. Strong winds are formed followed by heavy rain, crashing thunder, and flashing lightning. B 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. A 8. Usually happens and is over with quickly. B
