Question

Auroras are produced by _____.

differences in temperature between the mesosphere and thermosphere

extremely cold temperatures around the poles

ultraviolet radiation hitting the stratosphere

interactions among thermospheric gases and free electrons

Answer 1

Interactions among thermospheric gases and free electrons.

Step-by-step explanation:

Aurora borealis is a natural light display that results from interactions among thermospheric gases and free electrons. These disturbances in the magnetosphere are a consequence of solar wind. Auroras occur within bands around both polar regions, and are also known as polar lights, northern lights (aurora borealis) and southern lights (aurora australis).

Answer 2

Auroras are produced by
interactions among thermospheric gases and free electrons
