Question

The albedo is the highest in

• A. Water surface
• B. Bare soil
• C. Cropped area
• D. Ice

Hint:

Albedo values:
- Ice/snow: 0.5 - 0.9 (highest).
- Bare soil: 0.15 - 0.30.
- Water: 0.05 - 0.10 (lowest).

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
This question tests knowledge of albedo (reflectivity) of different surfaces.

Step 2: Detailed Explanation:
Albedo is the fraction of solar radiation reflected by a surface.
Ice (D) has the highest albedo (0.5 - 0.9).
It reflects most of the incoming solar radiation.
Other surfaces:
- Water surface (A): Low albedo (0.05 - 0.10).
- Bare soil (B): Moderate albedo (0.15 - 0.30).
- Cropped area (C): Moderate albedo (0.15 - 0.25).
Thus, ice has the highest albedo.

Step 3: Final Answer:
Thus, the albedo is highest in ice, which corresponds to option (D).
