Satellite images can not be used for which of the following?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Sub-surface exploration of oceans
Option (1) Sub-surface exploration of oceans — Not a use of satellite images (Correct). A satellite gives a continuous and synoptic view of a large area from above, that is, a picture of the surface. What lies below the sea surface does not show in such a picture, so sub-surface exploration of oceans is beyond what a satellite image can do.
Option (2) Weather forecast — A use of satellite images (Incorrect). Cloud cover over a wide area is seen at a glance, which helps forecast the weather.
Option (3) Monitoring of natural calamities — A use of satellite images (Incorrect). Floods, cyclones and other calamities can be watched as they spread.
Option (4) Surveillance of border areas — A use of satellite images (Incorrect). This is one of the strategic reasons for which satellite communication matters so much to the country.
NCERT (2025-26): “Satellite Communication … Satellites are mode of communication in themselves as well as they regulate the use of other means of communication. However, use of satellite in getting a continuous and synoptic view of larger area has made satellite communication very vital for the country due to the economic and strategic reasons. Satellite images can be used for the weather forecast, monitoring of natural calamities, surveillance of border areas, etc.…” |
