Answer:
Hello!
The correct options are: ionosphere and exosphere.
Step-by-step explanation:
Thermosphere:
- The thermosphere is a part of the Earth's atmosphere that lies above the mesophere and below the exosphere.
- The thermosphere stretches from 90 kilometers to 1000 kilometers above the surface of the Earth.
- The thermosphere contains two layers:
- Ionosphere
- Exosphere
- The ionosphere is the layer from which the Northern lights or Aurora Borealis originate. The sun's radiation in the ionosphere ionizes particles that emit the signature lights of the Aurora Borealis.
- Starting from 500 kilometers, the exosphere is the outermost layer of the thermosphere. The exosphere contains lighter gases such as helium and hydrogen. The exosphere houses the various GPS, telecommunication and weather satellites.
