What is radiation in the form of waves from the sun called? 

electromagnetic rays

100

convection takes place in _______ and _______.

gases and liquids

100

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 

100

What is a factor of surface currents?

Earth's rotation

100

What is the deep ocean currents that circle the earth's oceans?

Global Conveyor Belt

200

associated with good weather, air sinking, clear skies.

What is high pressure?

200

What is a convection current?

Movement of liquid of a liquid or gas, caused by unevenness heat.

200

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.

200

Once surface currents are set in motion, they are affected by three other factors:

Coriolis effect, presence of coasts, & horizontal pressure gradient

200

What Causes Deep Ocean Currents?

Earth's rotation, sun and salinity.

300

the boundary line where air masses meet.

What is fronts?

300

Convection is the transfer of _________.

heat

300

What helps wind move?

Ocean currents

300

surface ocean currents flow opposite of_____ ocean currents.

deep

300

True or False

Density differences are what principally drive vertical circulation in the oceans.

True

400

a mass of rising warm air that usually brings wet, stormy weather.

What is low pressure?

400

What is the rising of warm air currents and the falling of cold air currents?

convection

400

How do global wind patterns move?

From high pressure to low pressure

400

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.

400

Deep currents flow opposite of______ ocean currents.

surface

500

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?

500

What are the 3 types of heat transfer?

Radiation, Convection, and Conduction.

500

What causes the global wind patterns?

the spin of the earth combined with the uneven heating of earth's surface.

500

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.

500

How do deep ocean currents form?

By salinity and density of cold water.
