What else can I help you with?
Was there oxygen in the early earths atmosphere?
It is believed that the early Earth's atmosphere did not contain significant amounts of oxygen. Oxygen began to accumulate in the atmosphere around 2.4 billion years ago due to the emergence of photosynthetic organisms.
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.
Does the atmosphere contain oxygen?
The atmosphere contain different kind of gases and one these gases is oxygen.So your answer is yes.
What does the atmosphere contain in a layer that helps the stratosphere?
Atmosphere does contain many layers. A layer that helps in stratosphere is ozone.
The primitive earth's atmosphere did not contain?
Oxygen. The early Earth's atmosphere was composed primarily of gases such as carbon dioxide, water vapor, nitrogen, and methane. Oxygen levels increased with the development of photosynthetic organisms.
How was the early atmosphere diffrient from our current atmosphere?
pollution
Does the earths atmosphere contain nitrogen?
Yes. Earth's atmosphere is about 78% nitrogen.
Did earths original atmosphere contain methane and ammonia?
Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity. Over time, the atmosphere changed due to the presence of early life forms that produced oxygen through photosynthesis.
What percentage of the atmosphere is argon?
The standard atmosphere contain 0,934 % argon.
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.
What gases were there in the early atmosphere?
Oxygen
Does Saturn's satellite Titan's atmosphere contain nitrogen?
Yes. Titan's atmosphere is mostly nitrogen.
