100
this air mass brings in rain and cool weather
what is a cold front?
100
Form when two different large air masses meet and usually bring changes in the weather.
What are front?
100
something that can change day to day outside.
What is weather?
100
A horizontal movement of ocean water that is caused by wind and occurs at or near the ocean surface.
What is a surface current?
100
A stream-like movement of ocean water far below the surface.
What is a deep current?
200
This air mass forms over the ocean near the equator...
What is maritime tropical (mT)?
200
A type of front made of cold, dense air. Rain, snow, thurnderstorms and sometimes tornadoes are caused by this front. Usually, the precipitation does not last very long.
What is a cold front?

What is the weather forecast?
200
global winds, the Coriolis effect, and continental deflection.
What are the three main factors that influence surface currents?
200
Where density increases.
What parts of the ocean do deep currents form?
300
This is a dry, warm air mass.
What is continental tropical (cT)?
300
The front that forms when two air masses meet and neither one takes over. Often causes many cloudy days to occur in a row.
What is a stationary front?
300
What the conditions are like in a specific area over a long period of time.
What is climate?
300
Surface currents at the poles move West to East while surface currents at the Equator move East to West.
Which direction do surface currents move at the poles? At the Equator?
300
An decrease in temperature and an increase in salinity (saltiness).
What two (2) factors cause an increase in water density?
400
This is a wet, cold air mass.
What is maritime polar (mP)?
400
The type of front formed when a large mass of warm air takes over the cooler air mass. Usually produce rain, fog, or snow that lis light but steady.
What is a warm front?
400
In Canada, the weather is coldest in this season.
What is winter?
400
Clockwise=Northern Hemisphere Counter-clockwise=Southern Hemisphere
What direction does the Coriolis Effect move currents in the Northern Hemisphere? Southern Hemisphere?
400
water experiences:Freezing and Evaporation.
What are two ways that ocean water experiences increased salinity?
500
An air mass that formed over Northern Canada would probably be...
What is continental polar (cP)?
500
The type of front that develops when two cool air masses merge, forcing the warm air to rise and become trapped. Usually brings wind and preciptiation.
What is an occluded front?
500
This a wet area on land that floods easily
What is a swap?
500
They deflect, or change direction.
What happens when surface currents meet continents (i.e. land)?
500
Colder, denser water moves from the poles towards the Equator while warmer, less dense water moves from the Equator towards the poles.
How does temperature affect the direction of how deep currents flow?
