The three main types of clouds are cumulus, cirrus and this type of cloud.
What is stratus?

Compare and contrast the three types of heat transfer.
Radiation- direct transfer of energy in EM waves.
Conduction- transfer of heat from 1 substance to another that is touching it.
Convection- transfer of heat by the movement of fluid.
Radiation/conduction- through air short distances.
Conduction- better through solids than fluids.
Convection- better through fluids.

The direct transfer of electromagnetic waves is called:
A. radiation
B. conduction
C. heat
D. convection
What is A. radiation?
200
The sky looks blue because of:
A. the greenhouse effect
B. ozone
C. infrared radiation
D. scattering.
What is D. scattering?

Stratus clouds are made mostly of ice crystals.
What is false, Cirrus clouds are made mostly of ice crystals?
200
This type of radiation can cause skin cancer.
What is ultraviolet?

Explain why large bodies of water cause local winds to shift direction from day to night.
Large bodies of water heat up and cool off more slowly than land. During the day the wind blows from water to land and at night from land to water.
300
The upward movement of warm air and the downward movement of cool air is called a:
A. conduction path
B. sea breeze
C. convection current
D. global wind
What is C. convection current?
300
A form of precipitation in which rain freezes as it falls through the air is called:
A. hail
B. sleet
C. freezing rain
D. snow
What is B. sleet?
300
Wind speed is often measured with an anemometer.
What is true?
300
This is the most common kind of precipitation.
What is rain?

How could an increase in CO2 in the atmosphere raise Earth's temperature?
CO2 absorbs infrared radiation given off by Earth and keeps it warm in the greenhouse effect. If there was more CO2 more heat would be absorbed and Earth's average temperature would rise.
400
Clouds form when humid air is cooled to:
A. the dew point
B. the condensation point
C. 0° C
D. 30° C
What is A. the dew point?
400
Hailstones form only in the type of clouds called:
A. nimbostratus
B. cirrocumulus
C. cumulonimbus
D. altocumulus
What is C. cumulonimbus?
400
When you walk barefoot on hot sand, heat is transfered to your feet from the sand by radiation.
What is false, conduction would transfer the heat to your feet from the sand?
400
Winds are caused by differences in this.
What is air pressure?
400
Explain why having a funnel on a rain gauge increases its accuracy.
A funnel allows more water to be collected. When more water is collected, it is easier to measure slight increases in the amount of rainfall.
500
In the Northern Hemisphere, global winds that blow from the southwest to the northeast are called:
A. trade winds
B. polar easterlies
C. prevailing westerlies
D. prevailing easterlies
What is C. prevailing westerlies?
500
You compare the readings of wet-bulb and dry-bulb thermometers to measure:
A. humidity
B. temperature
C. wind chill
D. relative humidity
What is D. relative humidity?
500
A wind blowing toward the north is called a north wind.
What is false, wind blowing toward the north is called a south wind?
500
This is the average amount of energy of motion of each particle of a substance.
What is temperature?
500
What are the types of precipitation and how are they defined?
Rain- water at least .5mm in diameter.
Sleet- ice particles smaller than 5mm in diameter.
Freezing rain- rain that freezes on a cold surface.
Hail- ice pellets larger than 5mm in diameter.
Snow- 6-sided ice crystals.
