There are two important gases found in Earth's atmosphere today that was absent 3.8 billion years ago. Oxygen and Nitrogen. The Earth's atmosphere 3.8 billion years ago was composed mostly of Carbon Dioxide and Ammonia with smaller amounts of Methane and Water Vapor. Beginning around 3.5 billion years ago, bacteria formed and began converting Carbon Dioxide into Oxygen, through a process called photosynthesis, oxygenating the atmosphere. Oxygen began combining with the Ammonia forming Nitrogen around 2 billion years ago.
Oxygen and ozone were not present in Earth's early atmosphere. These gases were introduced later through processes like photosynthesis and the formation of the ozone layer.
oxygen, earth didn't get o2 until after the seas cleared up and algae started to form, and it took millions of years until we had the 02 content that we have now

What gases were present in earths today atmosphere?
The main gases present in Earth's atmosphere today are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and carbon dioxide (about 0.04%). Other gases such as water vapor, methane, and trace amounts of other gases are also present.
Where did the earths present atmosphere originate?
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
What gas is the largest component of earths present atmosphere?
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
Two gases that probably existed in Earth's early atmosphere are what?
Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.
What gases where present in early earths atmosphere?
The early Earth's atmosphere consisted mainly of carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia. Over time, as photosynthetic organisms evolved and produced oxygen, the atmosphere gradually transitioned to contain more oxygen and less carbon dioxide.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
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
Which of the following gases was NOT present in Earth's early atmosphere?
Hoyaaa
What gases were present in earths today atmosphere?
The main gases present in Earth's atmosphere today are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and carbon dioxide (about 0.04%). Other gases such as water vapor, methane, and trace amounts of other gases are also present.
Where did the earths present atmosphere originate?
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
What Active volcanoes are added to the early Earths atmosphere?
There are smallamount of volcanoes. They emit so2 and co2 gases.
What gas is the largest component of earths present atmosphere?
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
What do some of the gases in the earths atmosphere absorb?
Ozone gas is present as ozone layer. It absorbs the UV rays of the sun.
Two gases that probably existed in Earth's early atmosphere are what?
Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.
Where do these main gases come from?
they come from earths atmosphere and gases
What gases where present in early earths atmosphere?
The early Earth's atmosphere consisted mainly of carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia. Over time, as photosynthetic organisms evolved and produced oxygen, the atmosphere gradually transitioned to contain more oxygen and less carbon dioxide.
Two primary gases that were present when your solar system was formed?
Hydrogen and helium were the two primary gases present during the formation of our solar system. These gases dominated the early solar nebula from which the Sun and the planets eventually condensed.
