Question

Compared to Mars, our atmosphere's _____ is better to maintain a warm, livable temperature.

transparency
layer structure
thickness
age

Answer 1

The most appropriate answer is thickness. Earth's atmosphere is thicker than Mar's atmosphere. This could be due to the fact that the earth is more massive amd can hold a thicker atmosphere. The Martian atmosphere is composed mostly of carbon dioxide. The atmosphere is thin and cold so liquid water would evaporate or freeze.
