Main Ideas
When warm and cold air meet which one rises?
Warm air
What are the 2 things that affect the density of the ocean?
What is Salinity and Temperature
What is a cold front?
When cold air mass moves in and sinks under warm air mass
What is an air mass?
A large body air with the same temperature and humidty
When warm and cold water meet, which one sinks?
Cold water
What drives deep ocean currents?
What is density?
What is a warm front?
When warm air mass moves and rises over a cold air mass
Name two types of air masses
Maritime Polar
Maritime Tropical
Continental Polar
Continental Tropical
Substances rise or sink because of this
What is Density
How does thermohaline circulation affect global temperatures?
What is by bringing heat around the globe
What type of weather is associated with a stationary front?
Clouds with no rain
What forms when 2 air masses of different temperature and humidity meet?
A front is formed
What is density?
How much mass (stuff) is in a certain volume (space)
What is the global conveyor belt?
a large-scale system of ocean currents driven by temperature and salinity differences
What kind of front usually brings thunderstorms?
Cold or Occluded Fronts
How do maritime and continental air masses differ?
Maritime is humid and forms over the ocean
Continental is dry and forms over land
What is it called when things sink and rise, sink and rise in a loop
What is a convection current?
What would happen if the global conveyor belt stopped moving?
Their would be drastic changes in climates, as well as weather patterns changing
Define occluded front and its effects on weather.
A cold air mass catches up to a warm air mass and condenses it quickly causes severe thunderstorms
What are the characteristics of polar air masses?
