    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. 
    -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%.
