geospace
Geospace refers to the region of space surrounding Earth that is significantly influenced by Earth's magnetic field. This region extends from the upper atmosphere, where the atmosphere gradually thins and merges with outer space, out to roughly 10 Earth radii. It is a dynamic and complex environment where phenomena like auroras, radiation belts, and the solar wind interact with our planet.
The geospace is not a static boundary but a constantly changing volume. Its shape and extent are
Key components within geospace include the ionosphere, a region of Earth's upper atmosphere ionized by solar
