What are the 5 oceans of Earth?
Pacific, Atlantic, Artic, Indian, and Southern
100
True or False?
The ocean is actually deeper below the surface than the land is above the surface.
True
100
What causes ocean waves?
Prevailing winds.
200
What two days do we have exactly 12 hours of sunlight?
Vernal and Autumnal Equinox?
200
When is the Earth actually closest to the Sun?
At the Autumnal and Vernal Equinoxes
200
What is the coolest the ocean ever really gets?
33 degrees Fahrenheit, 1 degree Celsius.
200
What is the deepest point of the ocean?
Mariana Trench
200
What determines how strong or large a wave will be?
How much wind blows over the water.
300
What two things cause seasons on Earth?
Tilt of the Earth and revolution of the Earth around the sun.
300
What is the Latin word for Fall?
Autumnal
300
What is the main thing that causes surface ocean currents?
Prevailing winds.
300
What is the main thing that causes deep ocean currents?
Density difference in the ocean
300
What are breakers?
Waves that happen when the lower motion of wave begins to hit bottom and slow down. This causes the top of the wave to crash over the bottom of the wave.
You know them as the waves surfaces ride.
400
If your hemisphere is tilted towards the sun, what causes you to have summer heating?
Your get more direct sunlight which warms you up more and gives you longer days.
400
If your hemisphere is titled away from the sun, what causes you to have winter cooling?
Your days are shorter and you are getting less direct sunlight.
400
What is thermocline?
Drop in temperature in the ocean the further down you go.
400
What is pycnocline?
The increase in pressure as you go deeper into the ocean.
400
What causes the water to move in a wave?
The water molecules in a wave only move in a circular motion. The water itself does not move from one place to another.
500
If the northern hemisphere is tilted towards the sun, which of the following cities will have the longest day?
Anchorage, Alaska (61 degrees north)
Fairbanks, Alaska (64 degrees north)
Harmony, Minnesota (43 degrees north)
Fairbanks alaska
500
What is the Latin word for Spring?
Vernal
500
What direction the the gyres spin in each hemisphere?
northern hemisphere: clockwise
Southern hemisphere: counter clockwise
500
Other than the gyres, there are two other surface ocean currents. Where is one of them?
At the equator moving east and above Antarctica moving east.

Come up to the board and label the following parts of a wave: wavelength, crest, still water level, trough, wave height , and wave period.
