The thermosphere starts just above the
mesosphere
The mesosphere is 22 miles (35 kilometers) thick. The air is still thin, so you wouldn't be able to breathe up in the mesosphere.
Where do the auroras occur layer?
In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles—an aurora. Most auroras happen about 97-1,000 kilometers (60-620 miles) above the Earth's surface.
In which layer do auroras eg Northern Lights occur *?
Thermosphere. Troposphere. In which layer do auroras (e.g. northern lights) occur? Exosphere.
