•As you know, removing a calorie of heat from freezing pure water at 0 ° C (32 ° F) won’t change its temperature at all -- 80 calories of heat energy must be removed per gram of liquid water to form ice. More than 18,000 cubic kilometers (4,300 cubic miles) of polar ice, covering as many as 20 million square kilometers (7.7 million square miles) of surface, thaws and refreezes in the Southern Hemisphere each year -- an area of ocean larger than South America! How does the seasonal freezing and thawing of the polar ocean areas influence global temperatures? In the absence of this process (freezing and thawing of sea ice), how would temperatures and winds over the world be different? Answer: The freezing (winter) and thawing (summer) of ice in polar regions Would warm and cool the surrounding air in the respective seasons. Freezing ice removes heat from the water to the air, while the opposite is rue for thawing In the absence of these processes earth temperature True for thawing. In the absence of these processes, earth temperature extremes between poles and equator would be much greater than at present. Strong winds would result to balance pressure variations caused by temperature vatiation.
