Air masses and Fronts
True or false, Fronts are formed out of two air masses that collide
True, when two air masses collide they form an front
When viewing a weather map, what does the red symbol mean?
It symbolizes warm fronts, which bring cloudy and sometimes stormy weather.
True or false, deep currents are affected by cold weather above the ocean
True, deep currents need cold water to form and when there is cold weather above the surface the water absorbs it
True or false, Surface current only occur on the very surface of the ocean
What kind of weather do cold fronts cause?
Heavy, severe weather
When viewing a weather map, what do the large red L's symbolize
They symbolize low pressure, which is usually followed with warm humid weather
Where do ocean currents form?
Near the bottom of the ocean, sometimes on the ocean floor
What are the three causes of surface currents?
Continental collision, the Coriolis Effect, and Trade Winds
How are fronts formed?
When two air masses collide.
When viewing a weather map, what do the blue symbols mean?
They indicate a cold front
True or False, Deep currents heat the ocean through convection
False, Deep currents do not transfer heat, but they cool the water around them through convection
When a surface current collides with a Continent what is it called?
Continental collision
What are all types of air masses
mT, mP, cT, cP
When viewing a weather map, what do the large blue H's symbolize
They symbolize high pressure, which usually have cold drier winds to follow.
True or false, Deep ocean currents control the surrounding climate
True, Deep currents circulate the flow of cold and warm weather in the ocean, which plays a major of the climate.
True or false, surface currents help transfer heat across the earth's surface.
True, surface currents are a large part of earth's transfer of heat energy
Which of the above is not one of the four front types?
Cold fronts, Continental fronts, Stationary fronts, and Occluded fronts
Continental fronts
When viewing a weather map, what do the combined blue and red symbols mean?
It symbolizes a stationary front, which is both cold air masses and hot air masses that cancel each other out.
What causes deep ocean currents to form
The temperature and density of the water surrounding
Which country does the gulf stream flow towards?
England
