Ocean 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

Two types of ocean currents are

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

• Deep Currents
• Surface Currents
• High tide and low tide

• 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

Ocean water is more dense than fresh water at the same temperature due to differences in:  

• Wind patterns
•  Lifeforms
• Currents
• Salinity

Earth’s climate system is powered mainly by energy from:

• Tilt
• The sun
• Latitude
• The rain shadow
