Air masses & fronts
How does a warm front form
A warm front forms when a warm air mass moves over a cold air mass that is leaving the area
weather maps show
the movement of air masses
Surface currents are a result of
Global wind power
Why is upwelling (deep water moving to the surface) important
Upwelling provides nutrient rich water that sustains life
What happens to the warm air mass at a cold front
The cold front air mass replace the warm air mass
the movement of air masses
Is a large body of air with the same temperature and humidity throughout can cover thousands of square kilometers
Deep Ocean currents are a result of
Density
Two types of ocean currents are
Surface and deep
What happens to a warm front an a occluded front
A occluded front forms when a air mass is trapped between 2 cold air masses
A front
A place where two different air masses meet
The Coriolis Effect is caused by
Earth rotating on its axis
Deep Ocean currents caused by
Differences in density
In which direction does air move: from a cyclone to an anticyclone , or from and anticyclone to a cyclone
Inward to outward
Triangles show
A cold front
The Gulf stream carries what type of water from the east coast of The United States to the West coast of Europe.
Warm
As you go deeper in the ocean, the water is colder and less salty.
False
What are the sources regions for the mT air masses that affected weather in the united states
Gulf of mexico
what does a weather map show
Shows the weather over a part of Earth's surface
Helps meteorologists forecast the weather
Shows how the weather is like at a certain time
Helps scientists make predictions about the weather in the future
What happens to a current when it comes in contact with a continent or landmass?
It changes directions
What do we call the constantly moving system of deep-ocean circulation driven by differences in temperature and salinity?
Global Conveyor Belt
