Clouds absorb some of the heat that is emitted from Earth’s surface. How does this process affect the temperature of Earth’s surface?
This process cools Earth’s surface.
This process warms Earth’s surface.
This process produces extreme temperatures on Earth’ surface.
The temperature on Earth’s surface remains unchanged.
What is the role of tiny, suspended particles in the atmosphere in cloud formation?
Suspended particles help cool the air to the dewpoint.
Suspended particles help air to rise.
Suspended particles provide a surface on which water droplets can form.
Suspended particles allow the rate of condensation to equal the rate of saturation.
What is fog?
invisible water vapor
a cloud very near the surface of Earth
visible water vapor that forms at very high temperatures
a high altitude type of cloud
The prefix cirro- can be applied to different cloud types. What does this prefix mean?
clouds that contain precipitation
clouds at low altitudes
clouds at middle altitudes
clouds at high altitudes
Clouds can be classified according to altitude. Which of the following is a classification of cloud type by altitude?
altostratus
cumulonimbus
fog
vertical development
What is a cloud?
haze caused by pollution
a solid structure that generates heat
suspended water droplets or ice crystals
smoke that results from the interaction of water vapor and sunlight
Your science teacher points to the sky and says, “That is a cloud of vertical development.” What should you expect to see as you look up?
a cloud that extends across the sky
a cloud that is at low altitude
a cloud that extends upward from low altitude to high altitude
a cloud that is at middle altitude
Dewpoint is the temperature at which the saturation rate equals the condensation rate. What else must happen for dewpoint to be reached?
constant pressure
a change in pressure
no water vapor content
a change in water vapor content
What does the word nimbus mean?
ice
rain
low altitude
high altitude
