The first atmosphere would have consisted of gases in the solar nebula, primarily hydrogen. In addition there would probably have been simple hydrides such as are now found in gas-giant planets like Jupiter and Saturn, notably water vapor, methane and ammonia.
The next atmosphere, probably consisting largely of nitrogen (partly in the form of ammonia), carbon dioxide,water vapor and other gases, but no free oxygen. This amosphere was produced by outgassing from volcanism, supplemented by gases produced during the late heavy bombardment of Earth by huge asteroids.
Free oxygen did not exist until about 1.7 billion years ago (thank you plants).
What else can I help you with?
The most abundant gases are nitrogen and?
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
What Active volcanoes are added to the early Earths atmosphere?
There are smallamount of volcanoes. They emit so2 and co2 gases.
What are the most abundant variable gases in your atmosphere?
The most abundant variable gases in Earth's atmosphere are water vapor, carbon dioxide, and methane. These gases have varying concentrations that can fluctuate based on factors such as weather patterns, human activities, and natural processes.
What is 6 of the most abundant gases?
The most abundant gases in the Earth atmosphere are: nitrogen, oxygen, argon, carbon dioxide, neon, helium.
What are the 4 most abundant gases in the atmosphere excluding water vapor?
Co2ch4n2oo3
Pairs of gases that are the most abundant in earths atmosphere?
Nitrogen & oxygen.
What are the two most abundant gases in earths atmosphere presently?
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
What are the three most abundant gases in earths atmosphere?
The three most abundant gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%).
What gases were probably abundant in the earths early atmosphere?
It is believed that the early Earth's atmosphere likely consisted of gases like water vapor, carbon dioxide, nitrogen, and methane. Over time, as the Earth cooled and life forms evolved, the composition of the atmosphere changed due to processes like photosynthesis.
What are the two most abundant gases which make up the earths atmosphere?
Nitrogen N2 78.08% Oxygen O2 20.95%
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
Which of these is a component of the earths atmosphere?
these ??? There are no choices to choose from.
How much Hydrogen is in the Earths atmosphere?
This Question has not been answered yet. Genesis Roxx[:
Which gas was the most-abundant in the secondary-atmosphere?
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
What factor contributed to the formation of earths early atmosphere?
energy from the sun,lightening,earths heat triggered chemical reaction for the early gases of the earth combined
The most abundant gases are nitrogen and?
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
What 2 elements were contained in Earths first atmosphere?
Earth's first atmosphere was primarily composed of hydrogen and helium. These light gases were abundant in the early solar system and formed during the planet's initial formation. Over time, volcanic activity and other processes contributed to the release of gases, leading to the development of a secondary atmosphere.
