Earth's Zones
The Earth has five zones. These zones tell us something about the climate and where they are on Earth. They are marked by lines of latitude. Lines that run across the globe from side to side are called lines of latitude. (Lines that run from top to bottom are called lines of longitude. ) These lines are like a ladder. Lines of longitude are like the sides of a ladder. Lines of latitude are like the steps on a ladder.
The tropical or torrid zone lies near the equator. The equator is like a belt that goes around Earth's middle. Its northern border is marked by the Tropic of Cancer. The Tropic of Cancer is the line of latitude at about 23 degrees north of the equator. The tropical zone's southern border is marked by the Tropic of Capricorn. The Tropic of Capricorn is the line of latitude at about 23 degrees south of the equator. The tropical zone is warm or hot and humid year round. The seasons there don't change very much. Summer and winter are almost the same. The Earth's tropical rain forests are found in this zone.
