Heat Zones of the Earth – Class 5

Heat Zones of the Earth

Important for Class 5

The parallels of latitude divide the earth into different heat zones. There are three types of heat zones –

  • Torrid zone,
  • Temperate zone and
  • Frigid zone

Heat Zones of the Earth

The Torrid Zone

Places on the equator or those very close to it get direct rays of the sun for all or most of the year. The torrid zone refers to the area of the earth near the equator which is generally hot and humid. Thus these areas are called torrid zone. These places also get heavy rain all the year round. The torrid zone lies between the Tropic of Cancer and the Tropic of Capricorn due to which it is also called tropical zone.

The Temperate Zone

The temperate zone are not very hot because sun rays falling in these zones are slanted and cause less heat than in the torrid zone. There are two temperate zone. The north temperate zone lies between the Tropic of Cancer and the Arctic Circle. The south temperate zone lies between the Tropic of Capricorn and the Antarctic Circle.  In the temperate zones the four seasons spring, summer, autumn and winter are clearly felt.

The Frigid Zone

The frigid zone are very cold because rays of the sun fall at a great slant. So, these zones get very little heat and are always cold covered by snow. The summers are cool and the winters are freezing cold. There are two frigid zones. The north frigid zones lies between the Arctic Circle and the North Pole. The south frigid zones lies between the Antarctic Circle and the South Pole.

A. ANSWER THESE QUESTIONS.

  1. What kind of climate do the temperate zones have?
    The temperate zones are neither very hot nor very cold because rays of the sun in these zones fall slanted and cause less heat than in the torrid zone.
  2. How many heat zones does the earth have?
    The earth has three main heat zones – torrid zone, temperate zone and frigid zone.
  3. Give one reason why rays that fall at a slant give less heat?
    The sun rays fall almost straight at the equator while they fall slanting as we move away from the equator towards the poles. The rays that fall at a slant has to cover large area therefore it gives less heat.
  4. Why is the torrid zone much hotter than the frigid zones?
    The torrid zone gets direct rays of the sun for most of the year whereas at the frigid zone rays of the sun fall at a great slant. That is why torrid zone is much hotter than the frigid zone.
  5. Write difference between the temperate and frigid zone.
    At temperate zone the rays of the sun fall little slanted and causes less heat whereas in the frigid zone rays of the sun fall at a great slant. That is why temperate zone is neither too hot nor too cold whereas frigid zone are always very cold.

B. TRUE OR FALSE.

  1. Only the torrid zone gets direct rays from the sun.
  2. Seasonal changes are felt most in the temperate zones.
  3. The temperate zones are neither very hot nor very cold.
  4. The meridians of longitude divide the earth into heat zones.
  5. The south temperate zone lies to the south of the Antarctic Circle.
  6. Seasonal changes are felt least in the torrid zones.
  1. True
  2. True
  3. True
  4. False. The parallels of latitude divide the earth into different heat zones.
  5. False.
  6. The south temperate zone lies to the north of the Antarctic Circle.
  7. True

 

C. FILL IN THE BLANKS.

  1. The ________ zone lies just north of the Arctic Circle.
  2. The ________ zone lies just south of the Antarctic Circle.
  3. Places north of the tropic of ________ never get direct rays from the sun.
  4. The ________ zone is the hottest zone.
  5. The northern part of India lies in the ______ zone.
  1. north frigid zone
  2. south frigid zone
  3. cancer
  4. torrid zone
  5. north temperate zone
