5. OUR EARTH

6. LATITUDES AND HEAT ZONES

7. LATITUDES

8. IMPORTANT PARALLELS OF LATTITUDES
THE EQUATOR ’
TROPIC OF CANCER /2’ N
TROPIC OF CAPRICORN /2’ S
ARCTIC CIRCLE ½ ‘N
ANTARCTIC CIRCLE ½’ S
NORTH POLE ’N
SOUTH POLE ’S

9. Equator is the longest latitude which divides the earth into two equal parts.
Northern Hemisphere
Southern Hemisphere
All Parallel circles from the equator up to the poles are called Parallels of latitudes.
Equator is the longest latitude which devides

10. HEAT ZONES OF THE EARTH

11. HEAT ZONES OF THE EARTH TORRID ZONE TEMPERATE ZONE FRIGID ZONE

12. TORRID ZONE

13. TORRID ZONE Sun is exactly over head at least once in a year
[O-23 ½’ N Equator – Tropic of cancer
0-23 ½’ S Equator Tropic of Capricorn]
Sun is exactly over head at least once in a year
Receives maximum heat
Sun is exactly over head at least once in a year
Receives maximum heat

14. TEMPERATE ZONE

15. TEMPERATE ZONE Sun’s rays goes on decreasing Moderate climate
[23 ½’ N- 66 ½’N Tropic cancer Arctic circle
23 ½’S- 66 1/2’S Tropic of Capricorn to Antarctic circle]
Sun’s rays goes on decreasing
Moderate climate

16. FRIGID ZONE

17. FRIGID ZONE Sun rays are always slanting Provides less heat Very cold
{66 1/2’ N- 90’ N Arctic circle – North pole
66 ½’ S- 90’S Antarctic circle –South pole}
Sun rays are always slanting
Provides less heat
Very cold

19. CONCLUSION There are no such lines on the earth.
There are the imaginary lines made by man.
They help us to locate places.
Climate,Time,etc are determined by the help of these lines.
