OUR EARTH

LATITUDES AND HEAT ZONES

LATITUDES

IMPORTANT PARALLELS OF LATTITUDES THE EQUATOR 0’ TROPIC OF CANCER 23 1/2’ N TROPIC OF CAPRICORN 231/2’ S ARCTIC CIRCLE 66 ½ ‘N ANTARCTIC CIRCLE 66 ½’ S NORTH POLE 90’N SOUTH POLE 90’S

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

HEAT ZONES OF THE EARTH

HEAT ZONES OF THE EARTH TORRID ZONE TEMPERATE ZONE FRIGID ZONE

TORRID ZONE

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

TEMPERATE ZONE

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

FRIGID ZONE

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

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.
