Since the equator is midway between thepoles, it divides the earth, or sphere, into twoequal parts, called hemispheres (hemi=half). The half of the The hemi-spheres earth north of the equator iscalled the northern hemisphere, and that southof it the southern hemisphere. In which ofthese hemispheres is the United States ?. Fig. 117. — A ship in tiie ice that covers the sea in the cold, or frigid zone. The earth may also be divided into halvesby a circle running north and south throughboth poles. The western half, in which theNew World lies, is called the western eastern half, containing the Old World, iscalled the eastern hemisphere.
