The ionosphere is primarily composed of ionized gases, mainly electrons and positive ions, which are generated by solar radiation interacting with atmospheric gases. The key constituents include nitrogen (N2), oxygen (O2), and trace amounts of other gases such as argon (Ar) and various ions. These gases become ionized at altitudes ranging from about 30 miles (48 km) to several hundred miles (over 1,000 km) above the Earth's surface, influencing radio wave propagation and atmospheric processes.
