The imaginary east-west line encircling the Earth midway between the North and South poles is called the equator. The circumference, or distance around, the equator is about 24,900 miles (40,000 kilometers). The equator divides the Earth into the Northern and Southern hemispheres.The latitude of the equator is defined as zero degrees. Latitude is a system of imaginary east-west.Equator...he equator divides the Earth into the Northern and Southern hemispheres. The latitude of the equator is defined as zero degrees.
