A star is a massive collection of gas in space, that emits large amounts of energy.
Mars's atmosphere in composed primarily of carbon dioxide, with small amounts of nitrogen and argon, and trace amounts of oxygen, water vapor, carbon monoxide, and various other gasses.
The "terrestrial planets" are Mercury, Venus, Earth, Mars.
helium is made from the sun from the atmosphere and is believed to have a percentage of 70 percent. Well, actually, helium isn't made in the sun. But even then, the atmosphere of the sun is actually made up of 54% helium to be exact. (Not far off from what you said, though.) Correction: Helium IS produced in the sun! hydrogen is fused into helium and this liberates large amounts of energy.
The 3 important gasses (there are more) are:-NitrogenOxygenCarbon Dioxide
Nitrogen ~ 78% Oxygen ~ 21% CO2(and other gasses) ~ 1%
because in the inert gasses after ionisation electron is free and this gasses use for collection.
Many gasses surround the earth. The main gasses are Nitrogen, Oxygen, and Hydrogen. There are also very small amounts of other gasses. These gasses together make up the atmosphere.
"Trace gasses" are elements which are present in a sample, but in relatively very small amounts.
Yes, it's a mixture of gasses. Nitrogen and oxygen mostly but several other gasses in smaller amounts.
No.
It's burned. When it burns it creates a big volume of gasses. The force of these gasses expanding is then turned into mechanical energy.
The solar energy that is absorbed in gasses clouds and ozone is little. The UV spectrum is absorbed.
21% Oxygen 79% Nitrogen Trace amounts of other gasses
not horribly fast. They wont be depleted anywhere in this century. America sits on massive amounts of oil. Natural gas is fine. Metals may be a problem is we dont find another material beside titanium and steel
No. But it works a bit the other way around - gasses can absorb some radio energy.
Humans are a mixture of liquids and solids with small amounts of dissolved gasses.
"Trace elements" are elements which are present in a sample, but in relatively very small amounts. "Trace gasses" probably means gasses which are present in a sample, but in relatively very small amounts. the gases in earths atmosphere that take up less than 1% volume.
