Question

Explain why thermosphere is known as ionosphere.

Accepted Answer

The thermosphere is called the ionosphere because it contains a high concentration of ions, which are charged particles.

Solar radiation in this upper atmosphere layer causes the few remaining gas molecules to become ionised, forming ions.

This process is crucial for the reflection and transmission of radio waves, aiding communication.

The ionosphere's dynamic nature, influenced by solar activity, allows it to reflect different frequencies, facilitating long-distance communication.

Hence, the term "ionosphere" highlights the prevalence of ions in the thermosphere and its significant role in the interaction with electromagnetic waves for communication purposes.
