What molecule was not present in early Earths reducing atmosphere?
Oxygen (O2) was not present in early Earth's reducing atmosphere. It only became abundant in the atmosphere due to the photosynthetic activity of cyanobacteria and other early organisms.
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 was lacking from earths early atmosphere in the early precambrian?
oxygen
What gas was not part of early earths atmosphere?
oxygen
What gas was not a part of earths early atmosphere?
nitrogen
Was the earths early atmosphere made up of mostly oxygen?
no
What was the major contributor of oxygen to earths early atmosphere?
photosynthsis
Was oxygen present in early earths atmosphere what elements were present?
oxogen: unkown because of unknown life. elements: everything but pure potassium because that was not made till 1900's because it acts with air
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
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.
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
What gas do scientist think was missing from earths early atmosphere?
Methane gas
