80km-400km
The Ionosphere is the farthest layer from Earth among Troposphere, Stratosphere, Ionosphere, and Mesosphere. It extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface.
it is about 80 kilometers thick
274 kilometers from the earth exactly.
LOL I think that the ionosphere is not very big, you are not very big if you cannot spell so get off wikianswers!
274 kilometers from the earth exactly.
The ionosphere starts at an altitude of about 48 kilometers (30 miles) above the Earth's surface and extends upwards to about 965 kilometers (600 miles).
titi
The ionosphere extends from about 30 miles (50 kilometers) to 600 miles (1000 kilometers) above the Earth's surface. The exact height can vary depending on factors such as solar activity and time of day.
it begins at 559327 feet above aerths surface
Electrically charged particles are found in the ionosphere, a region of the Earth's upper atmosphere that extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface. The ionosphere contains ions and free electrons that are formed due to the ionization of molecules by solar radiation.
The Ionosphere or Mesosphere, both extending for hundreds of kilometers
The ionosphere is the part of the earth's atmosphere extending from about 30 miles (50 Kilometers) to the exosphere that contains ionized atmospheric gases. it influences radio propagation to distant places on the Earth.
