Why does water vapor condense?
Because as warm air rises it cools
100
What are the 5 types of precipitation?
Rain, Sleet, Freezing Rain, Snow, Hail
100
What are the symbols for cold, warm, and stationary fronts?
see slide 2
100
What are the three properties of air?
density, pressure, mass
100
What type of storm produces high winds, snow, and low visibility?
Blizzards
200
What causes water to change phase?
Adding or removing heat
200
Why does snow fall?
Because the temperature in the atmosphere is below 32 degrees F (0 degrees C). Water vapor condenses directly into ice crystals.
200
What happens when cold and warm air meet? Why?
Warm air rises because it is less dense
200
When altitude increases, what happens to air density?
Density decreases
200
What type (or types) of storms can cause houses to lose their roofs?
hurricanes and tornadoes
300
How do clouds form?
condensation in the atmosphere
300
How does sleet form?
Rain drops pass through a layer of air that is below 32 degrees F (0 degrees C) and freezes as it falls.
300
What type of front can cause steady rain for several days?
Stationary front or a warm front
300
What type of weather is associated with high pressure? Low pressure?
high- clear sunny low- cloudy rainy
300
Storm surge, high winds, and heavy rain are all characteristics of ___________________.
hurricanes
400
Where does water vapor come from?
Evaporation
400
Which type of cloud produces hail?
Cumulonimbus clouds (thunderstorm)
400
What type of fronts typically bring in cool, dry weather once the pass?
Cold fronts
400
What instrument measures air pressure?
Barometer
400
What type of storm often produces hail?
Thunderstroms
500
Draw a picture of the water cycle including at least four of the vocabulary terms.
See slide 1
500
What type of environmental factors affect the type of precipitation that falls?
Temperature and wind
500
Describe warm fronts. (can be a bulleted list)
-light rain for several days -leaves behind warm and humid weather -warm air moves over cold air
500
Where is air pressure the greatest?
at sea level
500
What causes storms to rotate?
wind shear
