Detailed explanation-1: -An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the north pole and the south pole, at 0 degrees latitude. An equator divides the planet into a northern hemisphere and a southern hemisphere. Earth is widest at its Equator.

Detailed explanation-2: -The equator is the most well known parallel. At 0 degrees latitude, it equally divides the Earth into the Northern and Southern hemispheres. From the equator, latitude increases as you travel north or south, reaching 90 degrees at each pole.

Detailed explanation-3: -Low latitudes are those locations found between the Equator (0 degrees N/S) and 30 degrees N/S. The middle latitudes are found between 30 degrees N/S and 60 degrees N/S. And the high latitudes are found between 60 degrees N/S and the poles (90 degrees N/S).

Detailed explanation-4: -The name is derived from medieval Latin word aequator, in the phrase circulus aequator diei et noctis, meaning ‘circle equalizing day and night’, from the Latin word aequare ‘make equal’.

Detailed explanation-5: -The Equator, Tropics, and Prime Meridian All three lines of latitude are significant in their relationship between Earth and the sun.
