Question:
Which of the following common natural surfaces on the Earth have highest albedo?
Which of the following common natural surfaces on the Earth have highest albedo?
Show Hint
Albedo is the fraction of incoming solar radiation that a surface reflects back.
Updated On: Jun 16, 2026
- Dry soil
- Clear water
- Needle leaf vegetation
- Snow and Ice
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Albedo is the fraction of incoming solar radiation that a surface reflects back. A bright, light-coloured surface reflects most of the sunlight and so has a high albedo, while a dark surface absorbs most of it and has a low albedo.
Step 1:
Dark surfaces such as clear water, dry soil and needle-leaf (forest) vegetation absorb a large part of the sunlight and reflect only a small fraction, so their albedo is low.
Step 2:
Fresh snow and ice are bright white and reflect a very large part of the sunlight, often 80 to 90 percent. This gives them the highest albedo among the listed natural surfaces.
Answer: Option (4) — Snow and Ice.
