100
Explain how clouds are formed.
Water is evaporated into water vapor, which is less dense. The water vapor reaches dew point and accumulates to form a cloud.
100
Once clouds reach it’s dew point, what happens?
It’s going to rain/precipitate
100
Explain weather.
State of atmosphere at a specific place and time
100
What is convection?
Rising of heat and sinking motion of cool energy
100
Describe the weather within the Continental Polar air mass.
Temperature: cold Humidity: dry
200
Name the three major types of clouds and their altitude association.
a) Cirrus-high b) Cumulus -medium c) Stratus -low
200
What is it called when water in plants is converted to vapor and released to the atmosphere?
Transpiration
200
Explain climate.
atmosphere conditions over a long period of time
200
List three places where convection occurs.
Atmosphere, mantle, sun’s convection zone, and/or ocean
200
Describe the weather within the Maritime Polar air mass.
Temperature: cold Humidity: wet
300
What atmospheric level and appearance does a cirrostratus cloud have?
High-level, layered
300
What is condensation?
Water vapor in the air that is changed into liquid water; forms clouds and fog
300
Name and describe 1 hypothesis to support global warming.
Global warming hypothesis – Carbon dioxide, water vapor, and methane (greenhouse gases) trap energy in the atmosphere. Climate variation hypothesis – rise in temperature is due to natural variations in climate Or combination of both, but explained.
300
How does convection relate to wind?
The sun heats the atmosphere causing warm winds to rise and cool winds to sink to earth
300
What happens at a front?
Two air masses meet but don’t mix. Weather happens here.
400
What does nimbus mean?
Rain
400
This provides delivery of atmospheric water to Earth.
Precipitation
400
Define air mass.
section of air with similar properties
400
How does convection relate to the atmosphere?
Warm air rises and cool air is more dense so it sinks. This cycling of air causes winds
400
What happens at a stationary front?
2 air masses come together but they don’t push each other out; it’s difficult to predict weather here
500
What atmospheric level and appearance does an altocumulus cloud have?
Middle level rain cloud
500
What is it called when precipitation doesn’t evaporate or transpire and doesn’t become ground water?
Run-off
500
Define front.
two air masses combine
500
How does convection relate to the ocean?
Warm water gets warmed by the sun and evaporates while cool water from the bottom rises to the surface to replace the warm water
500
The result of the weight of the column of air pushing down on an area is called?
Air pressure
