Core Concepts
ConceptDescription
🌍 LatitudeImaginary horizontal lines that measure distance north or south of the Equator (0°).
🌐 LongitudeImaginary vertical lines that measure distance east or west of the Prime Meridian (0°).
🕰️ Time ZonesEarth is divided into 24 time zones, each roughly 15° of longitude apart, representing 1-hour differences.
🧭 EquatorThe central line of latitude (0°) dividing Earth into the Northern and Southern Hemispheres.
🧭 Prime MeridianThe central line of longitude (0°), passing through Greenwich, England, dividing Eastern and Western Hemispheres.
🕓 GMT (Greenwich Mean Time)The standard reference time for the world, based on the Prime Meridian.
🇮🇳 IST (Indian Standard Time)IST = GMT + 5 hours 30 minutes, based on 82.5° E longitude.
