What is another word for e layer?
Pronunciation: [ˈiː lˈe͡ɪə] (IPA) 
The ionosphere is a complex atmospheric layer which includes the E layer. The E layer is also known as the Kennelly-Heaviside layer. This region begins about 90 km and ends around 160 km from the Earth's surface. It is characterized by a high concentration of free electrons, which make it important for radio communication and ionospheric study. The E layer is a vital part of the ionosphere and has many synonyms, including the E region, E-region plasma, and E-layer ionization. These terms all refer to the same layer of ionized gas that allows for high-frequency radio waves to bounce off the Earth's ionosphere and travel long distances.
