Why is the South Pole cold than the North Pole？ S1.______

Both polar regions of the earth are cold, primarily

because they receive far less solar radiation than the

tropics and mid-latitudes do. In either pole the sun S2.______

never rises more than 23.5 degrees above the horizon

and both locations experience six months of continuous

dark. Moreover, most of the sunlight that does shine S3.______

on the polar regions reflected by the bright white surface. S4.______

What make the South Pole so much colder than the North Pole S5.______

is that it sits on top of a very thick ice sheet, which itself sits

on a continent. Surface of the ice sheet at the South Pole S6.______

is more than 9000 feet in elevation—more than a mile

and a half over sea level. Antarctica is the highest continent S7.______

on the earth. In comparison, the North Pole rests in the middle

of the Arctic Ocean, which the surface of floating ice rides S8.______

only a foot or so above the surrounding sea. The Arctic Ocean

also acts an effective heat reservoir, warming the cold atmosphere S9.______

in the winter and is drawing heat from the atmosphere in the summer. S10.______
