What is a surface current?
A current that moves by wind
Are deep ocean currents Affected by wind
Wind plays no role in how deep ocean currents move
What are the 4 types of air masses and fonts
Arctic, Tropical, Polar and Equatorial
5 main parts of the weather
Precipitation, Humidity, Temperature, Pressure, Cloudiness, and Wind.
What causes most surface currents?
Global wind systems that are fueled by energy from the Sun
Where do deep ocean currents begin
in the North Atlantic
This air mass can bring heavy snow in the winter
Maritime polar
What causes weather?
Weather results from large global patterns in the atmosphere caused by the interactions of solar radiation, Earth's large ocean, diverse landscapes, and motion in space.
Which two currents together circle the North Atlantic Ocean
The Gulf Stream and the eastern boundary Canary Current
Where do deep ocean currents sink?
These deep waters sink into the deep ocean basins at high latitudes
Air masses always move in which direction?
Air masses move vertically
What are 7 things air maps show
Temperature, Dewpoint, Wind, Cloud Cover, Air pressure, Pressure tendency, and Precipitation.
What is the weakest ocean current
The Gulf Stream
why are deep ocean currents important
Deep ocean currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean.
How many main types of air masses are there
There are 6 main types of air masses
What can weather maps tell us?
A weather map shows weather conditions for a certain area.
How do continents affect the direction of surface currents?
The currents deflect, or change direction
What is Antacrtic bottom water
