• Demonstrate how places on Earth may be located using a coordinate system

  
• Geographic Coordinate System


  System used to locate places on Earth

  
• Equator


  An imaginary line around the middle of the Earth, dividing it into the Northern and Southern Hemispheres

  
• Unit of locating places

  Latitude and longitude

  
• Latitude


  The north-south position of a point on the Earth's surface, measured in degrees north or south from the equator

  
• Hemispheres of Earth


  Northern and Southern

  
• Latitude and longitude lines are imaginary

  
• Latitude lines meet at the poles but longitude lines do not meet
