Before there was any life on earth which gas was absent from earth's ancient atmosphere?
Oxygen was absent from Earth's ancient atmosphere before there was any life on Earth. The early atmosphere was composed mainly of gases like carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia.
Earths early atmosphere formed during the early Archean era which gas was generally absent from the atmosphere at that time?
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
What explains why oxygen was absent from earth early day atmosphere?
Oxygen was absent from Earth's early atmosphere because the planet's early life forms did not yet produce oxygen through photosynthesis. It wasn't until photosynthetic organisms like cyanobacteria evolved and began releasing oxygen as a byproduct that levels of oxygen in the atmosphere started to increase. This process took millions of years to significantly change the composition of Earth's atmosphere.
What gases exist today but were absent from early earth's atmosphere?
Gases like oxygen and methane were absent from early Earth's atmosphere but exist today. The increase in oxygen levels can be attributed to photosynthetic organisms, while methane is released through processes like decomposition and digestion in modern environments.
What element is present in protein that was not present in carbohydrates?
Proteins contain nitrogen, which is not present in carbohydrates.

Which of the four major spheres on the earth are absent or nearly absent on the moon?
The atmosphere.

Which of the four major spheres around earth are absent or nearly absent on the moon?
The atmosphere is nearly absent on the Moon. It has a very thin exosphere, but lacks a significant atmosphere like Earth's. Additionally, the biosphere is completely absent on the Moon as there is no known life there.
On Earth the four major spheres atmosphere hydrosphere solid Earth and biosphere interact as a system Which of these spheres are absent or nearly absent on the moon?
Of Earth's four major spheres atmosphere, hydrosphere, and biosphere are absent or nearly absent on the Moon. This prevents many of the natural processes we see on Earth from happening on the Moon.
What is the process in which nitrate and nitrite ions are converted into nitrous oxide gas and nitrogen gas?
The process is called denitrification. Denitrifying bacteria convert nitrate and nitrite ions into nitrous oxide gas and nitrogen gas in anaerobic conditions, where oxygen is limited or absent. This process plays a key role in the nitrogen cycle by returning nitrogen gas to the atmosphere.
What sphere is part of the carbon and water cycles but absent from the phosphorus cycle?
Atmosphere
Which gas was absent in the Early Archean Era?
Oxygen gas was absent in the Early Archean Era. This era is known for having low levels of oxygen in the atmosphere, with most of the oxygen being bound up in compounds such as water, carbon dioxide, and minerals.
What Chemical element is absent from carbohydrates?
Nitrogen is the chemical element that is absent from carbohydrates. Carbohydrates are composed of carbon, hydrogen, and oxygen atoms only.
What happens when nitrogen is absent in air?
When nitrogen is absent in air, the composition of the air changes, affecting the balance of gases needed for respiration and combustion. Oxygen levels increase, which may lead to more rapid oxidation and combustion. This can impact the environment and living organisms that rely on the normal balance of gases in the air.
What explains why oxygen was absent from earth early day atmosphere?
Oxygen was absent from Earth's early atmosphere because the planet's early life forms did not yet produce oxygen through photosynthesis. It wasn't until photosynthetic organisms like cyanobacteria evolved and began releasing oxygen as a byproduct that levels of oxygen in the atmosphere started to increase.
