A star is a massive collection of gas in space, that emits large amounts of energy.
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
The Sun produces heat through a process called nuclear fusion, where hydrogen atoms in its core combine to form helium, releasing vast amounts of energy in the form of heat and light. This process generates temperatures of millions of degrees, resulting in the Sun emitting heat and light that reaches the Earth.
It could possibly be many types of gasses. The most common is helium(He)
"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.
The gas that surrounds the Earth is primarily nitrogen (about 78%) and oxygen (about 21%), with small amounts of other gases such as argon, carbon dioxide, and trace gases. This layer of gases is called the atmosphere.
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
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.
The Earth's atmosphere is made up almost entirely of two gasses, oxygen & nitrogen. It's 21% oxygen and 78% nitrogen. So, these two make up 99%. The remaining 1% is a collection of other gasses.
Mars does have very small amounts of greenhouse gasses, but not enough to help warm the planet.
A colorless element that is one of the six inert gasses; occurs in trace amounts in air
