The composition of Earth's air is generally consistent across different locations, with nitrogen and oxygen being the main components. However, there can be variations caused by factors such as pollution, altitude, and proximity to sources of emissions. For example, areas with high levels of industry or traffic may have higher concentrations of pollutants like carbon monoxide or particulate matter in their air.

How do the gases in earths air differ from place to place?
The gases in Earth's air are mostly consistent globally, with nitrogen making up about 78% and oxygen around 21%. However, there can be variations in the levels of trace gases such as carbon dioxide, methane, and ozone due to factors like human activities, vegetation, and proximity to pollution sources. These variations can impact air quality, climate, and overall environmental health.
What is the air above the earths surface called?
The layer of air above the Earth's surface is called the atmosphere. It is composed of various gases and extends several kilometers into space.
What two gases is the earths atmosphere dominated by?
Nitrogen and oxygen, respectively, are the two most abundant gases in the earth's atmosphere.
How do gases in earth's air differ from place to place?
as molten rock cools, gases such as nitrogen, water vapor, and carbon dioxide were released. Some of the gases were trapped within earth , then many escaped as volcanoes erupted. but the atmosphere didn't always have the oxygen it has today. as plants spread across the planet they took in carbon dioxide from the atmosphere and released oxygen into the planet.
What force hold earths atmosphere in place?
That's gravity. Near the surface air has a density of about 1.2Kg/m^3. Air isn't that lightweight as you might think. We usually just don't lift it, but push it away, which is much easier.

How is pressure measured with a barometer?
by the earths gravitational pull the barometer can measure the amount of air pressure in the air, also because of carbons gases
Is air an example of pure substance?
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
Tiny air sacs where the exchange of gases between air and blood takes place?
alveoli
What is the difference between heat and air?
heat is hot, air is cold Heat and air differ in every respect; heat is a form of energy that is transferred by a difference in temperature, and air is a mixture of gases.
Why exchange of gases occur more efficently in air than in water?
Because in air the diffusion of gases takes place more quickly than in water.
What are the tiny air sacs called where the exchange of gases between air and blood take place?
Alveoli.

What two gases is the earths atmosphere dominated by?
Nitrogen and oxygen, respectively, are the two most abundant gases in the earth's atmosphere.
When does air become wind?
air is a mixture of many gases such as nitrogen, oxygen, carbon dioxide and noble gases. when these gases move from one place to another(usually from their higher concentration to their lower concentration) it is called wind...wind is basically moving air
Where in the body are Tiny air sacks where the exchange of gases between air and blood takes place?
Tiny air sacs where the exchange of gases between air and blood takes place are located in the lungs. These air sacs are called alveoli and are surrounded by capillaries where oxygen from the air enters the blood and carbon dioxide exits the blood into the air.
