What is air and where on earth does it occur?
Living in an Ocean of Air Most of Earth’s weather and life occur in the troposphere, the atmospheric layer closest to the Earth’s surface. At sea level, the force of air pressure equals 14.70 pounds per square inch (psi). This force comes from the mass of the entire column of air above each square inch of a surface.
Which is not a property of air?

How can we feel the presence of air?
Since air is invisible we easily forget that it is all around us. When we blow air in a balloon, we can feel the air pushing on the balloon. It’s the same with a tire or basketball. When we sit in front of a fan, we can actually feel the air molecules moving in the same direction.
Does air present in water?
When large amounts of water are present in the air other elements are present in lower amounts. The amount of water in the air can rise up to 4%. The lowest percentage of water in the air is 0,5%….What does air consist of?
| Nitrogen (N2) | 78% |
|---|---|
| Noble gasses | 1% |
| Carbon dioxide (CO2) | 0,03% |
| Water vapor (H2O) | 0,97% |
How do you feel the presence of air?
Since air is invisible we easily forget that it is all around us. When we sit in front of a fan, we can actually feel the air molecules moving in the same direction. That’s what wind is. Without air, balloons and birds and airplanes couldn’t fly.

What are some interesting things about the air?
Air is mostly gas. Air isn’t just gas. Air is important for living things. Carbon dioxide in the air can be both good and bad. Air also holds water. Air changes as you go up, up, up. Air is a protective cushion. There is life in the air. Air can move fast and far. Air pollution can ruin your outdoor plans.
What makes up most of the air in the atmosphere?
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen. Air isn’t just gas. While air is mostly gas, it also holds lots of tiny particles.
Why are we lucky to have air in our atmosphere?
On Earth, we’re pretty lucky to have an atmosphere filled with air. The air in our atmosphere acts as insulation, keeping the Earth from getting too cold or too hot. Ozone, another type of gas in the air, also protects us from too much sunlight. Air in the atmosphere can also protect us from meteoroids.
Where does the air in the soil come from?
This is because the water particles displaces the air, present between the soil particles and the air rises and escapes from the surface as bubbles. This air is used by insects such ants, beetles and earthworms to respire. The animals that live under the soil make deep holes and burrows in order to facilitate the free flow of air within the soil.
