The air we breathe is made up of small particles called oxygen and nitrogen. When the air is heated, the oxygen and nitrogen are combined and the energy from the heat turns into heat. This heat melts the ice and water in the air and makes it into air.
Does air come from trees?
Yes, trees produce oxygen and other gases that help to form the Earth’s atmosphere.
What gas is inhaled?
The gas inhaled is carbon dioxide.
Why do we breathe air?
The air we breathe is made up of about 78% nitrogen and 22% oxygen.
What is air and how it formed?
Air is made up of gas and molecules. Gas is made up of molecules that have lost energy. Molecules are made up of two atoms that have lost energy.
How old is the air we breathe?
The air we breathe is about 18,000 years old.
Can we breathe pure oxygen?

What is inside the air?
The air is made up of oxygen and nitrogen.
What air is made of?
The air we breathe is made up of oxygen and nitrogen.
Does water have air?

Do trees make air?
Trees make up about 60% of the Earth’s atmosphere. They take in carbon dioxide from the air and release oxygen.
Where does oxygen come from?
Oxygen comes from the air.
Who made air we breathe?
The first humans to create air we breathe were the Neanderthals.
What happens to air when heated?
The air in a room heated by a fire is heated as well. The air is vaporized and becomes a gas. The gas is composed of molecules of air and molecules of fire.
How is wind made?
Wind is made of tiny air bubbles that rise and fall.
Where do we get air?
There are three main ways to get air: through your lungs, through your nose, and through your mouth.
Do we breathe only oxygen?
No, we breathe a variety of gases, including oxygen, which helps us breathe.
What is air called in science?

What is the main source of wind?
wind is the motion of the air in the atmosphere.
How are air produced?
Air is produced when the warm air from the Earth’s surface meets the cold air from the Earth’s atmosphere. The warm air rises and the cold air is drawn down. This creates a vacuum.
When was oxygen created?
Oxygen was created on Earth about 4.6 billion years ago.
Why is wind cold?
Wind is colder because it travels in the atmosphere and is not affected by the Earth’s temperature.
How is air made on Earth?
The air on Earth is made up of tiny gas and dust particles that are heated by the sun and heated by the Earth’s atmosphere. The tiny gas and dust particles are then combined with the Earth’s atmosphere and heated again.
Are there atoms in air?
There are not atoms in air, but there are molecules. Molecules are made up of smaller units called atoms.
Which organ uses the most oxygen in human body?
The lungs. They produce about 20% of the oxygen in the human body.
How does air enter your body?
Air enters your body through the nose and mouth.
Do trees eat air?
Trees can photosynthesize to produce oxygen and water, but they also respire air. Air is necessary for photosynthesis and respiration, and trees need a lot of air to breathe.
