0° latitude is the line designating the Equator and divides the Earth into two equal hemispheres (north and south), while 0° longitude is an imaginary line known as the Prime Meridian. The 0° latitude is known as the Equator and the 0° longitude is known as the Prime Meridian . Where the Equator and the Prime Meridian cross each other is in the middle of the Atlantic Ocean, in the Gulf of Guinea off the coast of western Africa. So, the body of water is the Atlantic Ocean.
