The delineation between Earth’s ambiance and outer house isn’t a set boundary however quite a gradual transition. The idea usually refers back to the altitude at which atmospheric results grow to be negligible for sure sensible functions, akin to aerodynamic flight. As an illustration, above a sure altitude, standard plane can not generate adequate raise because of the air’s thinness.
Understanding this boundary is essential in aerospace engineering, house legislation, and meteorology. It informs the design of spacecraft and plane, the authorized framework governing actions in house, and the examine of atmospheric phenomena. Traditionally, defining this boundary has been important for establishing nationwide airspace sovereignty and regulating the usage of house.
