Question 4

Which of the following best describes the transformation of snow into glacial ice in Antarctica?

Accepted Answer

A) The transformation of snow into glacial ice in Antarctica takes less time than in midlatitude alpine glaciers because more snow falls in polar regions each year and slows the glacier formation process. 
B) The transformation of snow into glacial ice in Antarctica takes less time than in midlatitude alpine glaciers because there is more melting and refreezing in the midlatitudes and,therefore,it takes much longer there. 
C) The transformation of snow into glacial ice in Antarctica takes longer than in midlatitude alpine glaciers because the long summer days in Antarctica (up to 24-hours)results in more sunlight impeding the glacier development process. 
D) The transformation of snow into glacial ice in Antarctica takes longer than in midlatitude alpine glaciers because the dryness of the Antarctic climate and minimal snowfall as compared to wetter climates with constant snowfall.
