Question

Summarize variations in climate among three major zones as you travel south from the equator toward the South Pole.

Answer 1

If you're splitting into three zones, then you're probably classifying them according to torrid-temperate-frigid.

The torrid zone lies between the Tropics of Cancer and Capricorn. It is marked by year-round heat, and the two defining seasons of the year are wet season and dry season, with the wet season dropping large amounts of precipitation.

Proceeding south from the Equator, once you cross the Tropic of Capricorn, you are in the southern temperate zone. It is marked by thermal variability, and the two defining seasons of the year are summer (long days, warm temperature) and winter (short days, cool temperature).

Proceeding south from there, once you cross the Antarctic Circle, you are in the southern frigid zone. It is marked by year-round cold, and the two defining seasons of the year are polar day and polar night, due to a great deal more sunlight in half the year than the other half.
