100
what is a front
the boundary between air masses of different different densities and usually different temperatures
100
what is Weather
When clouds get water from evaporation and pours it out.
100
What can surface currents do?
Flow for thousands of kilometers and can reach depths of hundreds of meters
100
what are ocean currents
horizontal movement of ocean water that carries matter and energy from one part of the ocean to another part of the ocean.
100
where is the equator
the middle on the earth
200
what is a Cylcone
area in atmosphere that has lower pressure than the surrounding areas with wind spiraling clockwise towards the center
200
Atmospheric Movement
heat radiates from Earth
200
What do surface currents distribute and what do they influence?
Heat around the planet and influence climate around the globe
200
Gyres are important for what reason
for climate because gyres move heat energy from low latitudes near the equator to northern latitudes and toward the poles to bring warmer water toward the poles
200
why are the poles cold?
they get very little direct sunlight
300
Major air masses that influence weather in US
maritime, continental, polar, and tropical
300
High-Pressure Air Mass
An air mass with greater atmospheric pressure
than the surrounding air masses; air moves
away from the high pressure, traveling in a
clockwise direction
300
What are gyres?
Loops created by ocean currents.
300
The forces that act upon gyres are
Coriolis effect, gravity and friction from wind.
300
why is Alaska colder than Brazil
because Brazil is closer to the equator unlike Alaska
400
continental->forms over land/dry, polar->cold
Air mass Cp
400
Four basic types of air masses
1. Cold and dry
2. Cold and humid
3. Warm and dry
4. Warm and humid
400
Where are currents that move heat from the equator to the higher latitudes flowing relative to the continents?
North Equatorial Current.
400
Currents flow in what direction
basically in the same direction as the main wind that is blowing which effects surface currents.
400
what is maritime tropical
A warm, moist air mass that is formed over the ocean in tropical areas.
500
Major air masses that influence weather in US
maritime, continental, polar, and tropical
500
Stationary front
Forms when two air masses meet and stop moving.
Clouds and precipitation form at a stationary front.
500
Why is upwelling important?
The deeper water that rises to the surface during upwelling is rich in nutrients. These nutrients "fertilize" surface waters, encouraging the growth of seaweed and phytoplankton. These phytoplankton serve as the ultimate energy base for large animal populations higher in the food chain, providing food for fish, marine mammals, seabirds, and other critters.
500
Nutrients come to the surface for creatures and organisms to consume due to what
because of upwelling bringing deep cold water filled with nutrients to the surface of the ocean
