Hydrogen and helium are the two lightest gasses.

They are produced on or inside the Earth through chemical or radioactive processes.

They are the most common elements in the universe, but not found in our atmosphere in significant quantities becuase they escape into space.

When earth atmosphere formed what gases were lost because earth gravity was too weak?

When Earth's atmosphere first formed, lighter gases such as hydrogen and helium were lost to space because Earth's gravitational pull was not strong enough to retain them. These gases escaped into the atmosphere primarily due to solar radiation and the planet's high temperatures during its early formation. As Earth cooled, it retained heavier gases like nitrogen, carbon dioxide, and water vapor, which contributed to the development of a more stable atmosphere.


Why did earth first atmosphere not last?

The Earth's first atmosphere was primarily composed of gases like hydrogen and helium, which were eventually lost due to their low atomic mass. These gases escaped into space because the Earth's gravity was not strong enough to hold onto them, leading to the formation of a new atmosphere through processes like volcanic outgassing.


Did outer planets lose the light gases in their atmosphere?

Yes, outer planets like Jupiter and Saturn likely lost light gases from their atmospheres due to their gravity not being strong enough to retain these gases. Additionally, the strong solar wind and radiation in the outer solar system may have contributed to the loss of these gases over time.


Can earth gravity be lost?

No. Earth's gravity is a result of its mass.


Did the moon lose its volcanic activity because of its weak gravity?

No. The moon lost its volcanic activity because it is much smaller than Earth and so lost its internal heat more quickly.


If the moon had an atmosphere what would happened to it?

If the moon "had" or had had in the past an atmosphere, its gravitational force (about one sixth that of earths) would not have been strong enough for it to stop the gases dissipating into space.


The reason the jovian planets lost very little of their original atmosphere is due to their?

The reason the jovian planets lost very little of their original atmosphere is due to their strong gravity and magnetic fields. These factors help to trap and retain the gases that make up their thick atmospheres, preventing significant loss to space.


Have the giant gas lost most of their gases why?

No


Do earths ocean gain or lose waterconsidering evaporation and precipitation together?

No water is lost or gained because the water from precipitation comes from the water that has been evaporated.


What 2 chemicals was the Earth's first atmosphere composed of?

The Earth's first atmosphere was composed mainly of hydrogen and helium. These gases were eventually lost to space due to the Earth's gravity not being strong enough to hold on to them.
