Question:
Polar satellites
Polar satellites
Show Hint
Polar satellites scan the whole Earth — ideal for weather and environmental monitoring.
Updated On: May 2, 2026
- are high altitude satellites
- are widely used for telecommunication
- are used for environmental studies
- go around the earth in an east-west direction
- have time-period of rotation of 24 hours
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Polar satellites revolve around the Earth passing over the poles (north-south direction). They cover the entire Earth surface as Earth rotates beneath them.
Step 1: Key properties:
• Orbit in north-south direction
• Low Earth orbit
• Used for mapping, weather, environment monitoring
Step 2: Analyze options:
• (A) High altitude → False (they are low orbit)
• (B) Telecommunication → False (geostationary used)
• (C) Environmental studies → True
• (D) East-west → False
• (E) 24-hour period → False Final Answer: Used for environmental studies.
