Question

auroras occur where earths magnetosphere traps high - energy particles in which region of the atmosphere?
stratosphere
thermosphere
troposphere
magnetosphere

Explanation:

Auroras occur in the thermosphere. The thermosphere is the layer of the atmosphere where the Earth's magnetosphere traps high - energy particles. These particles interact with gases in the thermosphere to produce the light displays known as auroras. The stratosphere is mainly known for the ozone layer that absorbs UV radiation. The troposphere is the lowest layer where weather occurs. The magnetosphere is not a layer of the atmosphere but a region of space around Earth dominated by its magnetic field.

Answer:

thermosphere
