## FAQs on Global Latitudes & Longitudes Video Lecture - NCERT Video Summary: Class 6 to Class 12 (English) - UPSC

 1. What are global latitudes and longitudes?
Global latitudes and longitudes are geographic coordinates used to specify locations on Earth. Latitudes are the angular distance of a point north or south of the equator, while longitudes are the angular distance east or west of the Prime Meridian. Together, they form a grid system that helps in precisely identifying any place on the planet.
 2. How are latitudes and longitudes measured?
Latitudes are measured in degrees, minutes, and seconds, with the equator being 0 degrees and the poles at 90 degrees north and south. Longitudes are also measured in degrees, minutes, and seconds, with the Prime Meridian at 0 degrees and the International Date Line at 180 degrees. The degrees are further divided into 60 minutes, and each minute is divided into 60 seconds.
 3. Why are global latitudes and longitudes important?
Global latitudes and longitudes are crucial for navigation, cartography, and accurately locating any place on Earth. They provide a common reference system that enables precise communication of locations. These coordinates are widely used in GPS systems, mapping applications, and various scientific studies related to weather, climate, and geography.
 4. How can latitudes and longitudes be used to determine time zones?
Latitudes and longitudes help determine time zones by dividing the Earth into 24 longitudinal sections, each representing one hour of time difference from the Prime Meridian. As one moves eastward or westward, every 15 degrees of longitude corresponds to a time zone difference of one hour. This allows for standardized timekeeping across different regions of the world.
 5. Can global latitudes and longitudes be used to measure distance accurately?
While global latitudes and longitudes provide a precise system for location identification, they are not directly used for measuring distances. Instead, specialized calculations such as the Haversine formula or Vincenty's formulae are used to calculate the distance between two points specified by their latitudes and longitudes. These formulas take into account the spherical shape of the Earth and provide accurate distance calculations.
