# Latitude

## Explanation

The latitude is an arbitrary line used in the geographical coordinate system along with longitude to locate a point on the Earth. The latitude is the line or trajectory of a point on the surface of the Earth as it rotates from west to east. If the point is at the surface of the Earth at its center, the latitude passing through it is known as the equator. It is said to be at 0° to the arbitrary line that connects the center of the Earth to the point on the surface. This angle increases up to 90° towards either of the poles of the Earth at regular intervals. Each line drawn at those intervals are called as the parallels. The well-known parallels are the 23.4° N parallel called the Tropic of Cancer and the 23.4° S parallel called the Tropic of Capricorn.
