Conversely, the lowest point is the Challenger Deep in the Mariana Trench, plunging approximately 10,925 meters below sea level. Consequently, the surface at the equator is farther from the center of the Earth than the surface at the poles.
Understanding Earth's Flattening and Equatorial Bulge Effect on Height
This is the altitude where conventional aircraft wings no longer generate sufficient lift and orbital mechanics take over. When we calculate the mean radius of the planet—approximately 6,371 kilometers—we are effectively determining its average height from the center of mass to the geoid.
The exosphere, the outermost layer, gradually thins and extends up to 10,000 kilometers into space. Defining the "Height" of the Planet The most common reference point for the height of Earth is the average sea level, known as the geoid.
Earth's Equatorial Bulge: Why the Shape Flattens at the Poles
This geometric phenomenon means the "height" of the surface is not constant and varies by latitude, a crucial detail for satellite orbits and geodetic surveying. The Kármán line, established at 100 kilometers above sea level, is widely recognized as the edge of space.
