Origin and Evolution of ionosphere

First Known Use: 1926 year

Language of Origin: English

Story behind the word: The word 'ionosphere' originated from the combination of the words 'ion' and 'sphere'.

Evolution of the word: The term 'ionosphere' was first coined in 1926 by Robert Watson-Watt, a Scottish physicist, to describe the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. Over time, the word has become widely used in the field of atmospheric science to refer to the region of the Earth's atmosphere that is ionized by solar and cosmic radiation, playing a crucial role in radio wave propagation and communication.
