HYPSOGRAPHY OF THE CONTINENTS AND OCEAN FLOOR PDF

ETOPO1 is a 1 arc-minute digital representation of Earth's solid surface that integrates land topography and ocean bathymetry from numerous global and regional data sets. The histogram reveals two primary elevation groupings: the continents, several hundred meters above sea level, and the oceanic abyssal plains, roughly 4, meters below sea level. This distribution indicates that the crust of the ocean floor is fundamentally different from the continents, which has been confirmed by countless research studies. The dramatic steepening of the hypsographic curve at mountains and oceanic trenches can only be maintained by a dynamic Earth. On geologic timescales, such features would quickly erode or fill in with sediments.

Hypsographic Curve of Earth's Surface from ETOPO1

The hypsographic curve for the ocean floor is compared to a theoretical one which would be produced by sea floor spreading. Various models of ocean depth as a function of crustal age are used to generate models of ocean floor hypsography, to compare with the observed curve. The theoretical curves are adjusted for sedimentation and the presence of oceanic plateaus and other anomalous regions before comparison with the observed curve. The temperature of the hot material intruding the ridge crest has to be less, and the thickness of the lithosphere has to be greater than for PSM. A cooling half space model fits the data statistically worse than a cooling plate of finite thickness. The larger question concerning the elevation difference between the two modes in the hypsographic curve is also discussed. This is equivalent to explaining the isostatic balance between continent and ocean basins.
