Hypsometry (from Ancient Greek ὕψος (húpsos) 'height', and μέτρον (métron) 'measure') is the measurement of the elevation and depth of features of the Earth's surface relative to mean sea level.
On Earth, the elevations can take on either positive or negative (below sea level) values. The distribution is theorised to be bimodal due to the difference in density between the lighter continental crust and denser oceanic crust. On other planets within this solar system, elevations are typically unimodal, owing to the lack of oceans on those bodies.
