Oceanography

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

The Coriolis Effect is caused by

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

The Gulf stream carries _____________ water from the east coast of The United States to the West coast of Europe.

• Cold
• Warm 
• Freezing
• Fresh

Ocean currents have an affect on which two things

• climate and weather
• temperature and density
• land and sea
• equator and poles

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

Temperature and salinity variations in ocean water cause:

• Mid-ocean ridges
• Horizontal and vertical ocean currents
• Refraction of ocean waves
• Ebb and flow of the tides

Upwelling is when deep ocean waters rise to the surface. Upwelling will occur if:

• The dep water is saltier than the shallower water
• The deep water is denser than the shallower water
• Wind blows the shallow water along the coast away from the coast
• Wind blows the shallow water along the coast towards the coast.

The rise and fall of the water level of the oceans is called ___

• Wave
• Tide
• Deep ocean current
• Surface current

Which of the following causes tides?

• The gravity of the sun only.
• The gravity of the moon only.
• The gravity of both the sun and moon.
• The gravity of the earth.
