Under the Greek system of climatic classification, the world is divided into

Analyze the question: It asks how the Greek system of climate classification divides the world. The Greeks classified climate based on latitude and temperature, using the sun's heat received at different parts of the Earth.

Explain the concept: Ancient Greek scholars such as Aristotle and Parmenides divided the Earth into three broad thermal zones:

1. Torrid Zone (Tropics): lies between the Tropic of Cancer (23½°N) and the Tropic of Capricorn (23½°S). It receives direct, intense sunlight and is very hot.
2. Temperate Zones: lie between the tropics and the Arctic/Antarctic circles (23½° to 66½° in each hemisphere). They have moderate temperatures.
3. Frigid Zones: lie between the Arctic and Antarctic circles and the poles (66½° to 90°). They are extremely cold.

Solution (checking the options):

• A. hot, temperate and dry zones: "dry" is not part of the Greek system, which was based on temperature, not rainfall. Incorrect.
• B. torrid, equatorial and dry zones: "equatorial" and "dry" are not Greek divisions. Incorrect.
• C. temperate, frigid and hot zones: the three types are close, but "hot" is not the Greek term, and the standard expression is torrid, temperate, frigid. Incorrect.
• D. torrid, temperate and frigid zones: matches the Greek classification exactly. Correct.

Answer: D. torrid, temperate and frigid zones.

Tip: Remember the Greek system as "T-T-F": Torrid, Temperate, Frigid, going from the equator to the poles (hot → moderate → cold). If an option mentions rainfall (dry or wet), it is not the Greek system, because that is based on temperature and latitude alone.
