Important parallels of latitude include the Equator (0°), which divides the Earth into Northern and Southern Hemispheres; the Tropic of Cancer (23.5°N) and Tropic of Capricorn (23.5°S), marking the boundaries of the tropical zone; the Arctic Circle (66.5°N) and Antarctic Circle (66.5°S), defining the polar regions’ limits.

Significant parallels of latitude include the Equator (0°), which divides the Earth into the Northern and Southern Hemispheres and is the reference point for measuring latitude. The Tropic of Cancer (23.5°N) and Tropic of Capricorn (23.5°S) mark the boundaries of the tropical zone, where the Sun is directly overhead at least once a year. The Arctic Circle (66.5°N) and Antarctic Circle (66.5°S) define the limits of the polar regions, within which there are periods of continuous daylight or darkness during certain seasons. These parallels are crucial for understanding climate zones, seasonal variations, and the distribution of sunlight across the planet.
