Directions: Read the following information carefully to answer the questions that follow. When you imagine the desert, you probably think of a very hot place covered with sand Although, this is a good description for many deserts. Earth's largest desert is actually a very cold place covered with ice! Antarctica In order for an area to be considered a desert, it must receive very little rainfall. More specifically, it must receive an average of less than ten inches of precipitation which can be rain, sleet, hail or snow on the ground every year. Antarctica, the coldest place on earth, has an average temperature that usually falls below the freezing point and because cold air holds less moisture than warm air, the air in Antarctica does not hold much moisture at all. This is evident in the low precipitation statistics recorded for Antarctica, e.g., the central part of Antarctica receives an average of less than 2 inches of snow every year. The coastline of Antarctica receives a little bit more between seven and eight inches a year. Because Antarctica gets so little precipitation every year, it is considered a desert. When precipitation falls in hot deserts, it quickly evaporates back into the atmosphere. The air over Antarctica is too cold to hold water vapor, so there is very little evaporation. Due to this low rate of evaporation, most of the snow that falls to the ground remains there permanently, eventually building up into thick ice sheets. Any snow that does not freeze into ice sheets becomes caught up in the strong winds that constantly blow over Antarctica These snow filled winds can make it look as if it is snowing. Even though snowfall is very rare there, blizzards are actually very common on Antarctica.
In a passage author writes, 'And because of cold air holds less moisture than warm air, the air in Antarctica does not hold much moisture at all'. What does this means?A) Air in Africa holds more moisture than the air in Antarctica
B) Air at the mountains is colder than beach
C) Air in the second floor of house is warmar than air on the ground floor
D) Air surrounding the tropical islands hold less moisture than the air in Antarctica
Correct Answer: A
Solution :
In paragraph 2 the author writes, 'And because cold air holds less moisture than warm air, the air in Antarctica does not hold much moisture at all' because Africa is widely known to have a warm and hot, climate we can understand that the air in Africa holds more moisture than the freezing cold air in Antarctica
