Why can gases such as helium escape earth's atmosphere?
Helium can escape because it is the least dense element after Hydrogen.
Is there helium in Mars?
The tables I found list no helium, as measured by the Venera probes. If its there, it is only in minute traces. The atmosphere is extremely hot and dense, and a gas as light as helium would escape into space very quickly.
What does the earth's Moon's atmosphere consist of?
helium
Where do the elements in the sun's atmosphere come from?
Any elements in the sun's atmosphere other than hydrogen or helium were provided by earlier supernovas that exploded before the sun formed.The hydrogen and much of the helium in the sun's atmosphere originated directly in the big bang and have not changed since then.Some of the helium in the sun's atmosphere passed up in convection currents from the sun's core where it is fusing hydrogen to helium.
What is made mostly of hydrogen and helium?
Jupiter's atmosphere
Why can helium escape the earth's atmosphere?
Helium is lighter than oxygen and can escape the ozone.
Why can gases such as helium escape earth's atmosphere?
Helium can escape because it is the least dense element after Hydrogen.
Why can gases such as helium escape the earth's atmosphere?
because earth has gas particles that can let helium go
Why can a gas such as helium escape the atmosphere?
the molecues are lighter than the ones in the air.

Is there helium in the atmosphere?
Yes there is helium in the Earth's atmosphere.
Does Neptune have helium in its atmosphere?
Yes. helium is found in the earth's atmosphere.
Is there helium in the lithosphere?
no. helium is found in the atmosphere.
Why can helium escape earths atmosphere?
The helium atom does not form a diatomic molecule, unlike the main components of the atmosphere, nitrogen and oxygen, and it is a very light atom, actually the second lightest of all atoms (second only to hydrogen) and it is gravity which holds our atmosphere in place on the surface of the Earth, so the lighter the particle, the more easily it can escape into space.
What can helium do?
Helium can change the tone of a humans voice in an helium-rich atmosphere.
What percent of the Neptunian atmosphere is helium?
Planet Neptune's atmosphere comprises approximately 19% helium (±3.2%).
Why the Earth's atmosphere do not have helium and Hydrogen?
The atmosphere does not have helium and hydrogen because the two gases are too light to be there. Instead they are in the exosphere, above the atmosphere.
