Helium is a gas, except at extremely cold temperatures.
Helium is an pure element, not a compound or a mixture of gases.
helium.
Helium and nitrogen are two gasses that occur in the earth's atmosphere. Nitrogen is the most common gas in the atmosphere, at 78%. Helium is much less common at only 0.0005%.
The atmosphere (air).
the ozone layer for one, but it also trapes greenhouse gasses
It contains the ozone layer,different gasses,and to prevent direct rays from the sun.
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
our minor gasses in earth are helium oxygen and nitrogen
There are many gasses on Earth. Some of the gasses are: oxygen, nitrogen, argon, carbon dioxide, neon, helium, water vapor, and methane.

Helium is one of the noble gasses.

The atmosphere is Earth's outer layer, made up of Earth's gasses. The biosphere consists of all of Earth's living organisms.
helium is a gas. air is a bunch of different gasses.
Helium is NOT methane. They're both gasses, but different ones.
