Which of the following is not studied using cosmology? the universe’s origin the universe’s composition the melting of the polar ice cap the eventual fate of the universe

The melting of the polar ice cap is NOT studied using cosmology.

have a good day :)

The melting of the polar ice cap

Explanation:

Cosmology comes from the words "kosmos"  i.e. "world" and "logia" i.e. "study of". So basically it is the study of our world i.e. universe. technically speaking it the branch of Astronomy that focuses on origin of Universe, its dynamics and future of the universe.

Here the option "The melting of the polar ice cap" is not related to origin and fate of the universe and thus not studied in Cosmology.

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.
