no they don't.
The gases surrounding the Earth or any astronomical body is called the atmosphere.
Nitrogen & oxygen.
The atmosphere is made up of lots of different gases. It is impossible to name all of them as there are some that we havent found yet. Hope this helps
The gases that surround a star or planet are commonly referred to as its atmosphere. This gaseous envelope helps regulate temperature, protect from space debris, and play a crucial role in planetary processes such as weather and climate. The composition of the atmosphere can vary widely depending on the celestial body in question.
100%. However, I think you misunderstand. Every has in the atmosphere forms a percentage of the total gas in the atmosphere. The percetnages are ;- Nitrogen ; 79 % Oxygen ; 20% Other gases ; 1% The other gases include, Water vapour, Carbon dioxide, sulphur dioxide, methane, the noble (inert) gases ; (Helium, Neon, Argon, Krypton, Radon). #All these gases make up only 1% of the atmosphere, so individually they are in very small proportions.
My atmosphere is the same as your atmosphere since we all live on the same planet. Oxygen makes up about 19.5% of the atmosphere.
All matter has mass. All things with mass weigh something in a gravitational field. Gases are matter and on Earth are in a gravitational field, so they weigh something. Sometimes it would seem they are weight free or even buoyant because of the ther gas in the atmosphere. However in isolation with these effects removed they all have weight. An example of gas weights: Most atmospheric gases weigh around 30 g per 22.4 liters
About 10 feet of water equals 1 atmosphere or about 14.7 psi. The entire weight of the atmosphere exerts 1 atm of pressure at ground level therefore about 10 feet of water spread evenly across the face if the earth would weigh the same as all of the gases on the atmosphere.
Earth's gravity is what holds all the gases in the atmosphere around the planet. Gravity exerts a force that prevents the gases from escaping into space, creating the atmosphere that surrounds the Earth.
The gases surrounding the Earth or any astronomical body is called the atmosphere.
The Earth's atmosphere consists of all the gases that surround the planet, such as nitrogen, oxygen, carbon dioxide, and others.
Gases are evenly distributed throughout all levels of the atmosphere due to the process of diffusion. This means that gases move from areas of high concentration to areas of low concentration, resulting in a relatively uniform distribution of gases in the atmosphere.
An atmosphere.
carbon
The atmosphere itself is NOT an element. The atmosphere is a mixture of all the gases around the planet. Some gases are elements, but because there is more than one gas in the atmosphere, it is a MIXTURE of elements not an element itself.
hydrogen, helium and methane
They are what makes up the planet's atmosphere.
