What the equator is a imaginary line of?

Answer 1

The equator is an imaginary line that has been set to determine the exact halfway mark between the Northern an Southern hemispheres of the Earth. Most of it runs across the Atlantic and Pacific Oceans- the land masses that it covers are what is known as Equatorial Africa, which includes Southern Kenya, the Democratic Republic of Congo and Gabon, the Northern part of South America which includes Southern Colombia and Venezuela, and the Indonesian / Malaysian islands of Kalimantan and Sumatra. The Galapagos Islands are almost exactly on the Equator. There used to be a tradition on passenger ships of holding a ceremony whenever the vessels crossed the Equatorial line, where a bell would be rung and a ceremony conducted that involved a man dressed up as the Greek God Neptune, which may still be observed for the amusement of those wealthy enough to afford ocean cruises.

Answer 2

The Equator is a horizontal line of latitude, and is zero degrees. It splits the Earth into a Northern Hemisphere and a Southern Hemisphere.
