Class 10/6, Longitude and Latitude

In today's class we learned about longitude and latitude. We talked about how it makes each point on Earth unique.
Notes:

• a geographic coordinate system is a coordinate system used in geography that enables every location on Earth to specified by a set of number, etc. 
• the geographic grid is a system of imaginary arcs drawn in a grid pattern on Earth's surface
• Meridians are arcs drawn between the North and South poles. Each is numbered, according to a system known as latitude
• Values range from 0 degrees (prime meridian) to 180 degrees east to west longitude 
• Parallels are arcs drawn parallel to the equator and at right angles to meridians, each is numbered according to a system known as latitude
• What's the difference between parallels and meridians? - parallels: latitude, east to west, meridians: longitude, north to south
• Tropic of Cancer: 23.5 degrees N
• Equator- 0 degrees
• Tropic of Capricorn: 23.5 degrees S
• the area between the Tropic of Cancer and Capricorn is known as the tropics
• Meridians intersect at the poles
