What is the imaginary line at 0 degrees latitude called in geography, equidistant from both poles?

• A. Extratropical cyclone
• B. Hadley Cell
• C. Intertropical Convergence Zone
• D. Geographical Equator

Answer: (D)

Latitude lines form a grid that helps us measure how far north or south a place is from 0 degrees. The line at 0 degrees latitude is the equator. It sits exactly halfway between the North and South Poles, so it’s equidistant from both. The equator also marks where climate and daylight are typically tropical and serves as the primary reference for measuring latitude, with lines of latitude increasing north or south from it. The other terms refer to weather systems or atmospheric circulation and are not fixed lines: they describe processes or belts that occur near or around the equator but don’t represent the zero-latitude line itself.
