Shhhh LET’S Climate On Earth

FRIGID ZONE TORRID ZONE TEMPERATE ZONE Well, taking climate as a criterion , we can divide the world into three main Heat Zones namely- why FRIGID ZONE TORRID ZONE TEMPERATE ZONE Why do we have these different Heat Zones ?

HEAT ZONES SHAPE OF THE EARTH DISTANCE FROM THE SUN THE AREA HEATED It is mainly because of three major reasons- It is mainly because of three major reasons- HEAT ZONES SHAPE OF THE EARTH THE AREA HEATED DISTANCE FROM THE SUN

SHAPE OF THE EARTH The Earth is spherical in shape hence the Sun’s rays received is different in different parts of the Earth. Being spherical the maximum radiation is received at the centre of the Earth.

DISTANCE TRAVELLED BY THE SUN’S RAYS Since the Earth bulges at the centre the distance travelled by the sun’s rays is minimum at the centre and is the maximum at the poles.

AREA COVERED BY THE SUN’S RAYS At the centre the area heated is less compared to the poles , where the rays spread over a wide area. Hence the heat is more at the equator than at the poles.

Have you ever wondered what would happen if the temperature on the Earth goes on increasing? I Don’t Know!

Well, the ice caps in the Polar Region is slowly diminishing as the temperature of the Earth is going up due to global warming..

Let’s now see how these Zones are seen on the Earth They are seen between the major latitudes º º º º

The area between the Equator and the Tropic of Cancer in the Northern Hemisphere and the area between the Equator and the Tropic of Capricorn in the Southern Hemisphere is called the TORRID ZONE or the TROPICAL ZONE. TORRID ZONE

The area between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere and the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere is called the NORTH TEMPERATE ZONE and the SOUTH TEMPERATE ZONE respectively. NORTH TEMPERATE ZONE SOUTH TEMPERATE ZONE

The area between the Arctic Circle and the North Pole in the Northern Hemisphere is called the NORTH FRIGID ZONE and the area between the Antarctic Circle and the South Pole in the Southern Hemisphere is called the SOUTH FRIGID ZONE. NORTH FRIGID ZONE SOUTH FRIGID ZONE

Thus we have the three zones- FRIGID ZONE TORRID ZONE TEMPERATE ZONE

Do you know which parts of the world lie in these heat zones? Come , let’s see…..
