Air Masses/Fronts
Water Cycle
Air Masses
Fronts
100
What type of pressure system does this represent?
low pressure system
100
Name this step of the water cycle: when water changes from liquid to a gas
ex: puddle formed in the morning is gone by afternoon
evaporation
100
this type of air mass forms over the ocean, has warm temperatures, and has brings wet air with lots of moisture
Maritime Tropical
100
This front is formed when warm air slides up and over cold air. Clouds form with gentle rain or flurries.
Warm
200
What type of pressure system does this represent?
High pressure system
200
Name this step of the water cycle: plants releasing water vapor from leaves
ex: water droplets collecting on walls/roof of a greenhouse
transpiration
200
This type of air mass forms over the ocean, has cold temperatures, and brings wet air with lots of moisture
Maritime Polar
200
This front is formed when cold air pushes under war air, causing warm air to rise. Thunderstorms, high winds and more severe weather occurs.
Cold
300
What weather conditions does a low pressure system bring?
cloudy, precipitation
300
Name this step of the water cycle: water vapor cooling and returning to a liquid
ex: beads of water collecting on glass of ice water on a hot day
condensation
300
This type of air mass forms over land, has warm weather and has dry air
Continental Tropical
300
This front is formed when warm air and cold air meet and neither forces other one to move. Clouds form and it may rain or snow for several days.
Stationary
400
What weather conditions does a high pressure system bring?
sunny, clear skies
400
Name this step of the water cycle: water falls back to the ground
ex: rain, snow, sleet, hail
precipitation
400
What type of air mass forms over land, brings cold temperatures, and dry air
Continental Polar
400
What symbol on a map does this represent?
cold front
500
a large body of air with similar temperature, humidity, and air pressure
air mass
500
Name this step of the water cycle: water runs down Earth's surface and collects in oceans and other water sources.
ex: water trickling down a hill back into a lake
run-off/collection
500
What symbol does this represent on a map?
Warm front
600
the area where 2 air masses meet but do not mix
front
600
What is the driving force of the water cycle?
heat from the Sun
700
What would you expect to happen when a new air mass enters an area?
a change in weather will occur
