Web10 dec. 2024 · The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space. Cred: NASA's Scientific Visualization Studio 3. It changes — … WebThe Ionosphere. Regions of the ionosphere, showing the D, E, and F layers. Earth's atmosphere contains a series of regions that have a relatively large number of electrically charged atoms and molecules. As a group, these regions are collectively called the ionosphere.
