Question

Which is the coldest heat zone on the earth?
A) Torrid Zone
B) Frigid Zone
C) Temperate Zone
D) None of these

Answer 1

Hint:
The geographical zones are divided by the five main latitudes of the Earth. Climate is the only major difference between them by which they could be differentiated. The temperature of the Frigid Zone is cooler compared to the temperate and torrid zones.

Complete step by step solution:
The North Frigid Zone lies between the North Pole at $90^\circ {\text{N}}$ and the Arctic Circle at $66^\circ 33'{\text{N}}$. It covers $4.12\% $ of the Earth’s surface. The South Frigid Zone lies between the South Pole at $90^\circ {\text{S}}$ and the Arctic Circle at $66^\circ 33'{\text{S}}$ and covers $4.12\% $ of the Earth’s surface. The North Temperate Zone lies between the Arctic Circle at $66^\circ 33'{\text{N}}$ and the Tropic of Cancer at $23^\circ 27'{\text{N}}$ and covers $25.99\% $of the surface of the Earth. Between the Tropic of Capricorn at $23^\circ 27'{\text{S}}$ and Antarctic Circle at $66^\circ 33'{\text{S}}$ lies the South Temperate Zone which covers $25.99\% $ of the Earth’s surface. The Torrid Zone lies between the Tropic of cancer $23^\circ 27'{\text{N}}$ and the Tropic of Capricorn at$23^\circ 27'{\text{S}}$. $39.78\% $ of the Earth’s surface is covered by it. The midnight sun and the polar night for a part of the year is experienced by the two Frigid Zones or the Polar regions. The day at the poles i.e., the center of the zone is one year long with the daylight of six months and the other six months of night. This zone is the coldest heat zone on the Earth.

Thus, option (B) is correct.

Note:
The Torrid Zone, Frigid Zone, and the Temperate Zone are divided into the three broad heat zones on the basis of latitudinal extent. An ancient Greek scholar Parmenides first hypothesized the concept of the geographical zone and it was finally modified by Aristotle.
