What to Focus On

  • The Earth is an oblate spheroid called the Geoid.
  • The Equator divides Earth into Northern and Southern Hemispheres.
  • The Prime Meridian and 180° longitude divide Earth into Eastern and Western Hemispheres.
  • Latitude is measured north or south of the Equator.
  • There are 180 latitudes in all, at 1° intervals.
  • The Equator is the only Great Circle among latitudes.
  • The five main parallels of latitude determine the main heat zones.
  • Torrid Zone: 23½°N to 23½°S.
  • Temperate Zones: 23½°N to 66½°N and 23½°S to 66½°S.

Common Mistakes to Avoid

The Equator is just one more latitude, so it is the same type of circle as all the others.

Latitude and longitude mean the same thing because both are measured in degrees.

The Prime Meridian is the same as the Equator because both are zero lines on the globe.

Memory Tips

Earth's shape as an oblate spheroid called Geoid

Equator as the only Great Circle among latitudes

Latitude definition

180 parallels of latitude, 90 north and 90 south
