Ocean Intro to Freshwater Grade

The Coriolis Effect is caused by

• Earth rotating around the sun
• Earth rotating on its axis
• The tides
• Gravity

Due to the Coriolis Effect, water in the northern hemisphere moves

• clockwise
• counter clockwise
• both
• neither

Warm ocean currents generally come from

• The North Pole
• The South Pole
• The Equator
• Both A and B

Cold ocean currents generally come from

• The North Pole 
• The South Pole
• The Equator
• Either Pole

A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.

• Gulf Stream
• Global Conveyor Belt
• Surface Current
• Gyre

Surface currents are a result of

• Global Wind Patterns
• Earth's Rotation
• Density
• All of the above

Deep Ocean currents are a result of

• Global Wind Patterns
• Earth's Rotation
• Density
• All of the above

What causes vertical ocean currents?

• The phase of the moon.
• The gravitational attraction of the sun
• Commercial boating activities.
• The temperature and salinity of ocean water

Where is ocean water the densest.

• The surface
• The middle
• The bottom
• Lake Michigan

Which is the primary cause of surface winds on Earth?

• Unequal heating of the Earth
• Deflection in prevailing winds caused by the coriolis effect.
• Rotational speeds of Earth's surface at various latitudes.
