List down the components of air and each case, Outline atleast 3 uses of each component. Please guys help. I will give the brainliest. ​

The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapor, and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium, and hydrogen.

Explanation:

Oxygen- is an important gas, both for humans as well as the atmosphere. It supports breathing for living beings, but at the same time, oxygen is a combustible gas, which means, it can catch fire quickly.

Carbon dioxide- is infused into the air due to respiration. Living beings inhale oxygen and exhale carbon dioxide.

Water Vapor- When the water present in the water bodies evaporates due to heat, it rises and mixes into the atmosphere.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
