- Parallels of latitude are imaginary circles formed by Earth's daily rotation, parallel to the equator
- Equator (0°) is the largest latitude dividing Earth into Northern and Southern hemispheres
- Important latitudes: Tropic of Cancer (23.5°N), Tropic of Capricorn (23.5°S), Arctic Circle (66.5°N), Antarctic Circle (66.5°S)
