Wiktionary

  1. ionospherenoun

  1. Ionosphere

    The ionosphere is a region of the upper atmosphere, from about 85 km to 600 km altitude, and includes the thermosphere and parts of the mesosphere and exosphere. It is distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.

Examples of ionosphere in a Sentence

  1. Chris Scott:

    The images of neighborhoods across Europe reduced to rubble due to wartime air raids are a lasting reminder of the destruction that can be caused by man-made explosions, but the impact of these bombs way up in the Earth's atmosphere has never been realized until now. It is astonishing to see how the ripples caused by man-made explosions can affect the edge of space. Each raid released the energy of at least 300 lightning strikes. The sheer power involved has allowed us to quantify how events on the Earth's surface can also affect the ionosphere.

  2. Saptarshi Bandyopadhyay:

    Radio telescopes on Earth can not see cosmic radio waves at about 33 feet( 10 meters) or longer because of our ionosphere, so there's a whole region of the universe that we simply can not see, but previous ideas of building a radio antenna on the Moon have been very resource intensive and complicated, so we were compelled to come up with something different.
