Hint: Geographic, or Unprojected, refers to how we represent the Earth in spherical coordinates. \"Longitudes' ' and \"Latitudes\" are the most popular systems for finding locations on the globe. Longitude and latitude are both angles measured using the earth's centre as the starting point. A longitude is an angle measured to the east from the prime meridian (longitudes to the west are negative). The angle between the equator and the latitude is measured in degrees (latitudes to the south are negative).Complete answer: A geographic coordinate that describes the north–south position of a place on the Earth's surface is known as latitude. The angle of latitude varies from 0° at the Equator to 90° at the poles. Parallels, or lines of constant latitude, travel east–west as circles parallel to the equator.Longitude is a geographic coordinate that describes the east–west location of a location on the Earth's surface or a celestial body's surface. It is an angular measurement represented by the Greek letter lambda and generally represented in degrees. Meridians are lines that link locations of the same longitude.LATITUDELONGITUDEThe geographic coordinates that indicate the distance of a location north-south of the equator are referred to as latitude.Longitude refers to a geographic coordinate that indicates a point's east-west distance from the Prime Meridian.It's referred to as parallelism.It's referred to as meridiansThe lines are of various lengths.The lines are all the same length.It divides the world into heat zones.It is used to categorise time zones.There are 180 lines of latitude.There are 360 lines of longitude.Note: Because of the earth's rotation, longitude and time are inextricably linked. Local time (as determined by the location of the sun, for example) changes with longitude, with a 15-degree change in longitude equating to a one-hour change in local time. Longitude may be calculated by comparing local time to an absolute measure of time. The absolute time may be determined by a celestial occurrence observable from both places, such as a moon eclipse, or by a time signal broadcast by telegraph or wireless, depending on the era.
