Antarctic Circle: 
located at 66.5 ºS latitude


Arctic Circle: located at 66.5 ºN latitude

Intertropical Convergence Zone:  located where the northern and southern trade winds meet at the equator; characterized by stormy weather

North Polelocated at 90 ºN latitude

Polar Easterlies: global wind system located near the poles, starting at 60º N and S latitudes and extending Leeward

Prevailing Westerlies: global wind systems located in the northern and southern hemispheres in a zone between 30-60º N and S latitude

Revolution: amount of time it takes Earth to complete one trip around the sun; 365 days

Rotation: amount of time it takes Earth to complete one spin on its axis; 24 hours

South Pole
located at 90 ºS latitude

Subpolar Low: zone of low pressure located between the polar easterlies and prevailing westerlies

Subtropical High: high pressure zone associated with the trade winds

Trade Winds: global wind system located between 30ºN and 30ºS latitude
