What is an oval sphere called?

What is the amount of elevation on the surface of the earth known as?
The term elevation is mainly used when referring to points on the Earth’s surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.
What is absolute elevation?
Absolute altitude is the vertical distance of the aircraft above the terrain over which it is flying. It can be measured using a radar altimeter (or “absolute altimeter”). Also referred to as “radar height” or feet/metres above ground level (AGL). True altitude is the actual elevation above mean sea level.
What is geodetic elevation?
What is Geodetic Leveling ? Vertical surveying is the process of determining elevations above mean sea-level. In geodetic surveys executed primarily for mapping, geodetic positions are referred to an ellipsoid, and the elevations of the positions are referred to the geoid.
What is a high elevation for a city?
To be included on the list, the city needs an elevation of 3,000 feet (914 m) or higher.

Is Death Valley a desert?
Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert.
Why is death valley so deep?
Much of the extra local stretching in Death Valley that is responsible for its lower depth and wider valley floor is caused by left lateral strike-slip movement along the Garlock Fault south of the park (the Garlock Fault separates the Sierra Nevada range from the Mojave Desert).
