How do polar deserts exist?
 
  What will be an ideal response?

Question 2

How is it possible that coastal deserts exist in such a close proximity to ocean moisture?
 
  What will be an ideal response?

Answer to Question 1

Answer: Cold air cannot hold significant moisture, so climate conditions at these high-latitudes are dominated by the downward flow of cold, dry air.

Answer to Question 2

Answer: Most coastal deserts are located on the west edges of continents at latitudes where the prevailing wind is from the east. This means that atmospheric circulation carries dry continental air offshore rather than bringing moist oceanic air onshore.
