World Zones of Latitude – South Frigid Zone Which description best characterizes the South Frigid Zone, considering its latitudinal bounds and climatic conditions?

Introduction / Context:
Geographers divide Earth into zones of latitude to generalize climate and daylight patterns. The frigid zones are polar regions characterized by extreme cold and unique seasonal daylight cycles, including polar day and night.

Given Data / Assumptions:

• The South Frigid Zone is defined by parallels and circles of latitude.
• Climate is persistently cold due to low sun angles and high surface albedo (ice/snow).
• We compare equivalent phrasings of the same bounds.

Concept / Approach:
The South Frigid Zone extends from the Antarctic Circle (66½° S) to the South Pole (90° S). Within this belt, the Sun’s maximum elevation stays low, and long winters plus extensive ice cover ensure very cold conditions. Statements (a) and (b) are equivalent; (c) captures the climatic reality.

Step-by-Step Solution:

Verification / Alternative check:
Textbooks consistently define frigid zones between 66½° and the pole, with Antarctica as Earth’s coldest continent.

Why Other Options Are Wrong:

• Any single statement is accurate but incomplete relative to the inclusive option.

Common Pitfalls:
Confusing Arctic/Antarctic circles or mis-remembering the exact 66½° value.

Final Answer:
All of the above
