The closer a location is to the equator, the more________________it receives from the sun.
Energy
General weather patterns over a long period of time
Climate
Which renewable energy source uses underground steam?
Geothermal
In a place with no wind, the ________________ and weather never changes.
Temperature
What direction do the northern hemisphere currents flow?
Clockwise
Explain how the sun's energy is transferred to the air.
Energy from the sun transfers to Earth's surface. Some of that energy is then transferred to the air.
El Niño
Which renewable energy source uses plant waste?
Biomass
What direction do prevailing winds move at the equator?
From east to west.
In which direction do southern hemisphere currents flow?
Counterclockwise
What did the warm and cool cup experiment help to explain?
How energy is transferred from one place to another.
Warm air transfers energy to cool water.
Warm water transfers energy to cool air.
How does the Gulf Stream affect the climate of Florida's east coast in the winter?
Why are gas and oil considered non-renewable energy sources?
Because we are using them faster than the Earth is producing them.
What two things make wind?
Heating and cooling of Earth (changes in temperature) and the rotation of the Earth.
Name two things that determine how ocean currents move?
Wind and continents
Would there be wind if the Earth didn't rotate? Explain why or why not.
Yes. There would still be temperature differences, and temperature differences cause wind.
How did the Gulf Stream help win a war?
The strong currents allowed the American ships to travel faster than the British ships.
Name four types of renewable energy resources.
Wind, ocean, solar, hydroelectric, geothermal, biomass, and hydrogen.
Why does Christchurch, New Zealand experience lower temperatures during El Niño years?
The prevailing winds slow down or reverse direction.
Explain where warm and cool currents come from.
Warm currents come from the equator
Cool currents come from the poles.
