Definitions
What is a climate?
A general weather patterns over a long period of time.
what does El Nino years do?
changes the temperature of air and ocean.
Which currents have more energy, warm or cool?
Warm
The most powerful ocean current is called the...
Gulf Stream
How did the Gulf Stream help win a war?
The strong currents allowed the American ships to travel faster than the British ships.
What is climatology?
The study of weather patterns over a long period of time.
El Nino years mostly effects what 2 transfer points?
The air and the ocean.
The closer a location is to the equator, the more________________it receives from the sun.
Energy
What direction do the northern hemisphere currents flow?
Clockwise
What is the exact title of your Amplify book?
Ocean, Atmosphere, and Climate: Cold Years in New Zealand
What is a gyre?
a giant pattern of moving water that spans whole oceans and moves water from place to place in a circle.
What happens to the temperature during El Nino years?
It drops/gets colder.
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.
In which direction do southern hemisphere currents flow?
Counterclockwise
Where is Christchurch located in?
New Zealand.
What are prevailing winds?
Winds that move in one direction and are strong enough to push ocean currents.
What is the order of heat transfer?
Sun to land to ocean to air.
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
Throughout the unit, you pretended to be hired so you could find out more about El Nino temperature drops by studying what place?
Christchurch.
What is upwelling?
A process in which deep, cold water rises to the surface of the ocean.
What happens to ocean currents in El Nino years?
They reverse.
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.
Explain where warm and cool currents come from.
Warm currents come from the equator
Cool currents come from the poles.
Why does Christchurch, New Zealand experience lower temperatures during El Niño years?
The prevailing winds slow down or reverse direction.
