Layers in earth's atmosphere are defined as regions in which

a.
air mixes together

b.
different types of weather occur

c.
planes cruise due to jet stream currents

d.
the temperature of the air remains the same

b. different types of weather occur

Explanation:

the temperture varies as one moves higher up, the higher one goes the cooler the temperature becomes. So that creates a change in weather condition.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
