उत्तर
- The orbit of a geostationary satellite is above the equator.
- The time of revolution for the earth around itself and that for geostationary satellites to revolve around the earth are the same.
- 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.
- 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.
