What is a line parallel to the equator?
Three of the most significant imaginary lines running across the surface of the earth are the equator, the Tropic of Cancer, and the Tropic of Capricorn. While the equator is the longest line of latitude on the earth (the line where the earth is widest in an east-west direction), the tropics are based on the sun’s position in relation to the earth at two points of the year.
