उत्तर

  1. The orbit of a geostationary satellite is above the equator. 
  2. The time of revolution for the earth around itself and that for geostationary satellites to revolve around the earth are the same.
  3. The polar regions lie at very high latitudes and are outside the field of view of satellites positioned above the equator, so they cannot be properly observed.
  4. These satellites are stationary with reference to the Earth they can observe a specific portion of the Earth continuously. 

Therefore, geostationary satellites are not useful for studies of polar regions.
