Explained
Step-by-step explanation:
- Ionosphere is the outermost layer of the Earth's atmosphere,extending from 60 km to 1,000 km altitude.
- It mainly consists of ionized gases by the solar radiation.
- It is very important layer to Earth because it influences the radio propagation to distant places on Earth.
- Being ionized it reflects high frequency(shortwave) radio waves to the sky as well as to the Earth by a technique called "skip" or "skywave" propagation for the communication over long distances.
