    Locating Places with Latitudes and Longitudes

    • The grid formed by latitudes and longitudes helps locate places.
    • Each location on Earth can be identified using its specific latitude and longitude coordinates.

    Longitude and Time

    • Earth's rotation causes each longitude to face the Sun once a day, resulting in the highest point of the Sun in the sky (midday or noon).
    • Earth rotates 360 degrees in 24 hours, meaning it rotates 15 degrees in one hour and 1 degree in four minutes.
    • Local time is determined by the longitude of a place.
    • All places on the same longitude share the same local time.
    • Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC) is the local time of the Prime Meridian.
    • Places east of the Prime Meridian are ahead of UTC, and places west are behind UTC.

    Standard Time

    • Due to different local times based on longitude, standard time zones were established.
    • A standard meridian (roughly in the middle of a country or region) is selected to determine the standard time for that area.
    • For example, India's standard meridian is 82.5° E longitude, and the local time of this meridian is used as the Indian Standard Time (IST).
    • IST is 5 hours and 30 minutes ahead of UTC.
