Question: Identify the correct sequence of natural surfaces according to their albedo: Ocean (b) Fresh snow (c) Grass (d) Desert Sand Choose the correct answer from the options given below :
Options:
A < B < C < D
C < A < D < B
C < A < B < D
A < C < D < B
🔑Key Points:
-Albedo is the measurement of the reflectivity of sunlight by any object.
-Objects reflecting more sunlight have high albedo while those reflecting less have a low albedo.
Surfaces Albedo (%): Fresh snow (80), Desert sand (40), Grass (25), Ocean (6)
Therefore, The increasing order of albedo of natural surfaces is Oceans < Grass < Desert < sand < Fresh snow.

🔴Additional Information:
-Objects with higher albedo are cooler in temperature and while those with lower albedo are hotter in temperature.Â
-The albedo of a given region depends on soil composition and moisture, vegetation types, level of urbanization, etc.
-Earth’s overall albedo is measured to be 30%.
