The Earth's __________ consists of layers of gases that are held in place by the gravity of our planet.__________ is a valuable gas in the air that is required by __________ and other living organisms to stay alive.The __________ is the lowest layer of Earth's atmosphere and site of all weather on Earth.The __________ is a layer of Earth's atmosphere where temperature increases due to the absorption of sunlight by the ozone.AtmosphereOxygen, HumansTroposphereStratosphereSep 10, 2024 · 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.
Air is a mixture of gases which makes up the Earth's atmosphere. The composition of air is unchanged until the elevation of approximately 10000m. Visit BYJU’S to learn about chemical composition of air and properties.

All the air in a space as big as a house can be squeezed into a small tank. On the other hand, air can expand almost indefinitely. If all the air were removed from the inside of a house and then 1 cubic foot (0.03 cubic meter) of air were supplied, the air would expand throughout the building.
This is a 12 minute educational film that explains air pressure, weight, molecular composition, and other scientific properties of air.
