Which one of the following experiences the least annual range of temperature ?

Answer»

Equator
Tropic of Cancer
Tropic of Capricorn
Arctic Circle

Solution :The sun's rays are concentrated more directly in the region round the equator. So the temperature is higher in these regions. When we move from the equator, due to the curvature of the earth, the sun's rays strike the earth surface at an angle and are ALSO SPRED over a LARGER area. So these regions do not heat to the same extent as do the equatorial regions
