As the gases go higher in the atmosphere they start to compose or join together at some point which causes them to change since there is mixture of more than one gas, sometimes they form a different element when certain gases form
Helicopters need air for the rotor to generate lift, and as the moon hasn't got an atmosphere a helicopter won't go anywhere.
airplanes rely on lift rockes rely on jets rocketsd can go out of the atmosphere airplanes cant
Saturn's atmosphere is thick.Thick.thickSaturn's atmosphere is extremely thick and in fact it is so thick that you'd get crushed if you entered. It is made out of 96.3 molecule hydrogen and 3.25 helium. Traces of many other gases have been found.Thick. Basically, the giant planets consist MAINLY of atmosphere or liquified gases, etc.
stratosphere
It can go out to space, or it can be trapped by various gases in the atmosphere, i.e., greenhouse gases such as CO2 and water vapor.
Because the "greenhouse gases" act similarly to a greenhouse. The heat goes through the gases (glass panes) and is stored on Earth (greenhouse) and is unable to exit back into the atmosphere (sky). Google "greenhouse effect" and go look at the images, the pictures on the first page will help you to understand my analogy.
The so-called "greenhouse gases" CO2, methane, water vapor, etc.
The higher you go, the less dense it would get
Most energy (electricity and transport) comes from burning fossil fuels (coal, oil and natural gas). When fossil fuels burn, they emit carbon dioxide, a greenhouse gas, into the atmosphere. So if you save energy, then not so much fossil fuel is burnt and less greenhouse gases go into the air.

Greenhouse gases trap the heat rising from the warmed surface of the earth. Hence, increasing the temperature of earth. This is called the greenhouse effect. If extra greenhouse gases are added, then we have an accelerated greenhouse effect, which causes global warming.
Greenhouse help grow plants that are not used to being in that environment. Greenhouses are warmer than the outside air. You could also go to google.com and search what greenhouses do for more details... hope I could help
Many of the activities that humans do have a direct or indirect link to contributing gases into the atmosphere. For example if you want to go swimming at a pool which is a 5 minute drive from your house, the swimming would not produce greenhouse gases into the air but the 5 minute drive would. But if you participated in a car race that would have a direct link to producing greenhouse gases becouse when you drive a normal petrol or gasoline powered car you would be producing carbon dioxide into the air.
This is an interesting question that gets deeper then you may wish to go. A shuttle launch will release water vapor, which is a greenhouse gas. It is the most common of greenhouse gases. Water vapor is ignored though in terms of man contribution to greenhouse gas because it dissipates quickly and mans contribution to this gas is insignificant. The water vapor produced in a launch remains in the atmosphere for a few hours. Much of the raw material used to create this water vapor also comes from the atmosphere to start with. Man produces almost 0.3% of all greenhouse gases, virtually none of this amount though is from the space program.
China is the biggest annual producer of greenhouse gases, recently overtaking the US. The US remains historically the country that has put the most greenhouse gases into the atmosphere. China is catching up here.
