Vocabulary
What is radiation in the form of waves from the sun called?
electromagnetic rays
convection takes place in _______ and _______.
gases and liquids
These wind systems not only influence the weather, they also determine when and where ships and planes travel most efficiently, it occurs with the help of earth's rotation.
the Coriolis Effect
What is a factor of surface currents?
Earth's rotation
What is the deep ocean currents that circle the earth's oceans?
Global Conveyor Belt
associated with good weather, air sinking, clear skies.
What is high pressure?
What is a convection current?
Movement of liquid of a liquid or gas, caused by unevenness heat.
How does the Coriolis Effect affect wind circulation in the Northern Hemisphere?
Air coming from the poles turn to the left and air coming from the equator turns to the right.
Once surface currents are set in motion, they are affected by three other factors:
Coriolis effect, presence of coasts, & horizontal pressure gradient
What Causes Deep Ocean Currents?
Earth's rotation, sun and salinity.
the boundary line where air masses meet.
What is fronts?
Convection is the transfer of _________.
heat
What helps wind move?
Ocean currents
surface ocean currents flow opposite of_____ ocean currents.
deep
True or False
Density differences are what principally drive vertical circulation in the oceans.
True
a mass of rising warm air that usually brings wet, stormy weather.
What is low pressure?
What is the rising of warm air currents and the falling of cold air currents?
convection
How do global wind patterns move?
From high pressure to low pressure
How does salinity affect density currents?
Changes in salt concentration at the ocean surface affect the weight of surface waters. Fresh water is light and floats on the surface, while salty water is heavy and sinks.
Deep currents flow opposite of______ ocean currents.
surface
The way Earth's rotation make in the Northern hemisphere curve to the right and winds in the Southern hemisphere curve to the left.
What is Corilois Effect?
What are the 3 types of heat transfer?
Radiation, Convection, and Conduction.
What causes the global wind patterns?
the spin of the earth combined with the uneven heating of earth's surface.
How does temperature affect density currents?
When a substance is cooler at the surface, the density increases in the substance and the substance sinks due to the increased density. It moves slowly across the ocean floor towards the equator.
How do deep ocean currents form?
By salinity and density of cold water.
