Question

who will answer this question. i will mark his answer as brainliest. why is upper part of thermosphere known as ionosphere​

Answer 1

Answer:

Its name comes from the fact that gases in these layers are excited by solar radiation to form “ions,” which have an electrical charge. Parts of the ionosphere overlap with Earth's magnetosphere. That's the area around Earth where charged particles feel Earth's magnetic field.

Answer 2

Answer:

The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Radiation causes the atmosphere particles in this layer to become electrically charged (see ionosphere), enabling radio waves to be refracted and thus be received beyond the horizon.
