Answer: Tropical Zone
The tropical climate zone stretches from the Tropic of Cancer at 23.5 degrees north latitude to the Tropic of Capricorn at 23.5 degrees south latitude, with the equator centered within this zone. Climate within the tropical zone varies from the tropical wet regions of the rain forest, to the drier arid and semi-arid climate of north Africa or central Australia. Within the tropical wet zone, the weather remains hot and muggy, with frequent rainfall and little temperature variation. The arid and semi-arid regions experience wet, warm summers and cooler, drier winters, with much greater temperature variation than the tropical wet zone.
Temperate Zone
Extending from the southern edge of the Arctic Circle to the Tropic of Cancer in the northern hemisphere, and the northern edge of the Antarctic Circle to the Tropic of Capricorn in the southern hemisphere, the temperate climate zone falls between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year of any climate zone. Climate within the temperate regions ranges from the cold, snowy winters of New England to the balmy, moderate weather associated with the Mediterranean or Southern California. Much of the United States, Europe and the southern half of South America fall within this climate zone.
Polar Zone
The polar climate zones fill the areas within the Arctic and Antarctic Circles, extending from 66.5 degrees north and south latitude to the poles. Characterized by a short, cool summer and long, bitterly cold winter, the polar zone features frequent snowfall, particularly during the winter months. The far northern portions of Canada, Europe and Russia fall within this climate zone. Farther north and south, the ice caps that make up Greenland and Antarctica represent a sub-zone of the polar climate region known as the ice cap zone. Within the ice caps, temperatures rarely, if ever, rise above freezing, even during the warmest months of the years.
