Concept:The Greek system is one of the earliest climate classifications, grouping the world into broad latitudinal zones based on temperature.
Explanation:Ancient Greek scholars divided the Earth into three main temperature belts from the Equator to the poles.
The torrid zone lies between the Tropic of Cancer and the Tropic of Capricorn, receiving the most direct sunlight and having the highest temperatures.
The temperate zone is located between the tropics and the polar circles in both hemispheres, experiencing moderate seasonal temperatures.
The frigid zone covers the polar regions around the Arctic and Antarctic circles, where temperatures remain very low throughout the year.
This simple thermal classification was based purely on temperature and the angle of the sun's rays, not on rainfall, vegetation, or air masses.
Modern classification systems, such as those of Köppen, later improved on this Greek framework.
Answer:D. torrid, temperate and frigid zones
