WebThe ionosphere is composed of three main parts, named for obscure historical reasons: the D, E, and F regions. The electron density is highest in the upper, or F region. The F region exists during both daytime and nighttime. During the day it is ionized by solar radiation, during the night by cosmic rays. Web10 dec. 2024 · The ionosphere is where Earth’s atmosphere meets space The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. …
