Latitude and Longitude are a system of coordinates used to pinpoint locations on the Earth's surface. Latitude measures how far north or south a place is from the equator, which is at 0 degrees. It ranges from 0 degrees at the equator to 90 degrees at the poles. Longitude measures how far east or west a location is from the Prime Meridian, which is at 0 degrees. It ranges from 0 degrees to 180 degrees. Together, these coordinates create a grid that helps in navigation and mapping, allowing us to identify any location on Earth accurately.
