Question

The thermosphere is: 1. the layer of atmosphere closest to the Earth’s surface where weather occurs. 2. supports long distance communication because it reflects outgoing radio waves back to Earth without the use of satellites. 3. the layer where auroras form when electrically charged particles from the sun collide with gas molecules releasing energy visible as light of different colors

Answer 1

Answer:

3

Explanation:

The thermosphere is the layer of the atmosphere that is below the exosphere (essentially outer space) and the mesosphere. This layer has significant overlap with the ionosphere, but all of the thermosphere is not electrically charged and therefore the two layers are not interchangeable.

Most auroral activity occurs in the thermosphere, and a large number of satellites are found orbiting the Earth in the part of the atmosphere.
