Question

Distinguish between latitudes and longitudes.

Accepted Answer

The difference between latitudes and longitudes is as follows:

Basis Longitude Latitude

Meaning The meridians of longitude refer to the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian The parallels of latitude refer to the angular distance, in degrees, minutes, and seconds of a point north or south of the Equator.

Name Lines of longitude are often referred to as meridians. Lines of latitude are often referred to as parallels.

Reference point $0 °$ Longitude is called prime meridian. $0 °$ Latitude is called equator.

Division It divides the earth into eastern hemisphere and western hemisphere. It divides the earth into Northern
Hemisphere and Southern Hemisphere.

Number These are $360$ in number: $180$ in the
eastern hemisphere and $180$ in the
western hemisphere. These are $180$ in number: $90$ in the southern hemisphere and $90$ in the northern hemisphere.

Importance It helps to determine the time of a place It helps to determine the temperature of a place.

Equality The distance between two longitudes is not equal everywhere. On Equator, it is maximum and towards north and towards south it reduces and on North and South poles the distance between two longitudes becomes zero. The distance between two latitudes remains equal everywhere on the Globe.
