Read the paragraph from the introduction [paragraphs 1-4]. The amount of daylight in a location depends on how far north or south it is from the equator. The equator divides Earth into two halves called hemispheres. The Northern Hemisphere is above the equator. The Southern Hemisphere is below the equator. Distance from the equator is measured in latitude. Lines of latitude run east-west. Lines of longitude run north-south. These are not real lines on the planet. They only exist on maps and are used to find any place on Earth.

A
