latitude同temperature問題..

Given the fact that the South Pole is -90 and the North Pole is +90, I am assuming "increasing latitude" means increasing absolute value of latitude.

Note that Earth has an axial tilt of the Earth with respect to the sun, which is about 23°. This means every year, the Earth will tilt either towards the sun or away from the sun depending on the season. Since the Earth is a sphere (somewhat of a sphere), the North Pole or South Pole will have the largest range of movement. Temperature on the Earth is largely due to the sun. Therefore, the distance from the surface of the Earth to the sun affects the temperature of the surface greatly. Because the movement due to the axial tilt of the Earth will increase with increasing latitude, the temperature variation will also be increased with increasing latitude.
