Marine Currents

What causes ocean currents in the Northern Hemisphere to curve to the right?

• Earth's orbit around the Sun
• Earth's spinning on its axis
• Earth's magnetic field
• Earth's force of gravity

Where is ocean water the densest.

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

Two types of ocean currents are

• local and global
• sea and land
• surface and deep
• warm and cold

Temperature and salinity differences in ocean water cause:

• Mid-ocean ridges
• Deep Currents
• Surface Currents
• High tide and low tide

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

• Cold
• Warm 
• Freezing
• Fresh

As you go deeper in the ocean, the water is colder and less salty.

• True
• False

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

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

What process brings the deep cold ocean currents up to the surface?

• Conduction
• Global Wind Patterns
• Convection Currents
• Temperature and salinity
