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. This average provides a baseline for understanding the planet's overall size and serves as the foundation for global positioning systems.
True Height of Earth Center to Surface Measurement
This results in an equatorial diameter that is about 43 kilometers larger than the polar diameter. The Kármán line, established at 100 kilometers above sea level, is widely recognized as the edge of space.
The equatorial bulge adds approximately 21 kilometers to the planet's diameter compared to the polar diameter, making the calculation of an average height essential for scientific and practical applications. This staggering depth is a result of the Pacific Plate subducting beneath another plate.
True Height of Earth Center to Surface Measurement
Conversely, the lowest point is the Challenger Deep in the Mariana Trench, plunging approximately 10,925 meters below sea level. This fundamental shape dictates that the distance from the center to the surface varies significantly depending on where you are located.
