A region of this earth's environment in which ionization due to incoming solar radiation impacts the transmission of radio waves. It expands from a height of 70 kilometers (43 miles) to 400 kilometers (250 miles) over the surface.
The an element of the Earth's environment beginning at an altitude of approximately 50 kilometers (31 kilometers) and extending outward 500 kilometers (310 kilometers) or higher.
The comparable area of the environment of another world.
the exterior area associated with planet's environment, beyond the exosphere; it includes a higher concentration of free electrons and ions, and stretches from about 50 miles to about 250 miles over the earth's surface, nevertheless height reveals everyday and seasonal variation, and also the structure regarding the particles when you look at the ionosphere can also be impacted by events such as for instance solar flares.
