Question

The principal gases of the homosphere (by volume) are:

A) Oxygen, nitrogen, and carbon dioxide
B) Nitrogen, helium, and argon
C) Carbon dioxide, methane, and water vapor
D) Hydrogen, oxygen, and neon

Answer 1

The principal gases of the homosphere are nitrogen, oxygen, and carbon dioxide.

Step-by-step explanation:

The principal gases of the homosphere (by volume) are:

1. Nitrogen
2. Oxygen
3. Carbon dioxide

The atmosphere is composed of approximately 78% nitrogen, 21% oxygen, and about 0.04% carbon dioxide, with trace amounts of other gases. Nitrogen is the most abundant gas in the atmosphere, followed by oxygen and carbon dioxide. These three gases play crucial roles in maintaining the Earth's climate and supporting life.
