HEAT ZONES OF THE EARTH 

Heat zones are the different zones of the earth where the sun's ray fall differently, thus causing different climate patterns. 

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

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.
