Zones of the Earth: The distribution of temperature is
not uniform on the surface of the Earth.
Different temperature zones are
found on the earth.
It goes on decreasing as we move
from the Equator to the Poles.
Type of temperature Zones:
Zone: The zone which lies between the Tropic of Cancer (or 23° 30' North
latitude) and the Tropic of
Capricorn (or 23° 30' South latitude) with the Equator in between, is known
as the Tropical or Torrid Zone.
In this zone the Sun's rays arc vertically overhead
during a greater part of the year.
It receives the maximum insolation.
Zones or Polar Zones: The zones which lie between the
Arctic Circle (66°30" North latitude) and North Pole (90° North latitude)
and the Antarctic Circle (66° 30'South latitude) and the South Pole are called
the Frigid Zones or Polar Zones.
They receive the minimum insolation,
so they are very cold.
Zones: The zones which lie in between the
Tropical Zone and Polar zones have moderate temperature so
they are called the Temperate Zones.
