Question:
As a first approximation the Earth is considered as a sphere of average radius R - 6370km. This neglects a bulge at the equator, flattening at the poles, and local irregularities. What fraction of the Earths radius is the tallest mountain? The depth of the deepest ocean trench? The average ocean depth? Does your result mean that one can treat the Earth as a perfect sphere when planning the operation of a satellite?
