    Question

    Based on the distribution of the cumulative percent surface area of the Earth at different elevations and depths (with reference to sea-level) shown in the figure, which of the following is FALSE?

    A.

    Larger proportion of the surface of the Earth is below sea-level

    B.

    Of the surface area above sea-level, larger proportion lies below 2 km elevation

    C.

    Of the surface area below sea-level, smaller proportion lies below 4 km depth

    D.

    Distance from sea-level to maximum depth is greater than that to the maximum elevation

    Correct option is C

    Given:

    • A hypsographic graph:
      • Shows % of Earth's surface at or above/below various elevations.
      • Most of the Earth's surface lies below sea level (oceans).
      • Land area mostly lies below 2 km elevation.
      • Ocean floors mostly lie between 0 and -4 km, with steep drop-off after that.
      • Deepest point in oceans (~ -11 km) is greater in depth than the height of Mount Everest (~ +8.8 km).

    Graph Interpretation Highlights:

    • Sea level (0 km) aligns with ~29–30% of the cumulative surface area → ~70% of Earth's surface lies below sea level.
    • From 0 to 2 km elevation: majority of the land surface is here (about 25% of Earth's surface).
    • From 0 to -4 km depth: less than half of the area below sea level.
    • From -4 km to -11 km: major ocean basin → this is a significant chunk (about 40%).

    Let’s evaluate each option:

    A. Larger proportion of the surface of the Earth is below sea-level
    True
    Graph shows ~70% of surface area lies below 0 km.

    B. Of the surface area above sea-level, larger proportion lies below 2 km elevation
    True
    Most land lies between 0 and 2 km elevation.

    C. Of the surface area below sea-level, smaller proportion lies below 4 km depth
    False
    From the graph, the majority of the ocean floor lies below -4 km → especially between -4 and -6 km. So this is clearly false.

    D. Distance from sea-level to maximum depth is greater than that to the maximum elevation
    True

    • Mariana Trench: ~ -11 km
    • Mount Everest: ~ +8.8 km
      → Depth is greater.

    Correct Answer (False Statement): (C)
