Answer:
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.

- Where did you go last night? - I went to a party with my friends.
