The first atmosphere of the earth was probably mostly hydrogen with some simple hydrides such as water vapor, methane and ammonia.
Vulcanism and asteroidal bombardment eventually replaced this with an atmosphere of mostly nitrogen, with carbon dioxide and some of the inert gasses.
What else can I help you with?
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.
Why is the percentage of argon in the earths atmosphere today the same as it was in the earths early atmosphere?
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.
Which gas was the least plentiful in earths early atmosphere?
Oxygen was the least plentiful gas in Earth's early atmosphere. The atmosphere primarily consisted of carbon dioxide, water vapor, nitrogen, and small amounts of other gases. Oxygen levels rose significantly over time due to the process of photosynthesis by early life forms.
What gas was not present in the atmosphere when earth first form?
carbon dioxide
Why gas was lacking from earths early atmosphere in the early Precambrian era?
Gas was lacking from Earth's early atmosphere in the early Precambrian era because the primitive atmosphere was composed mainly of hydrogen and helium, which were lost over time. The formation of the Earth's magnetic field and the development of the ozone layer prevented the atmosphere from being stripped away by solar winds, leading to the accumulation of gases like carbon dioxide and water vapor over billions of years.
What gas was not a part of earths early atmosphere?
nitrogen
What gas was not part of early earths atmosphere?
oxygen
What gas was lacking from earths early atmosphere in the early precambrian?
oxygen
What gas do scientist think was missing from earths early atmosphere?
Methane gas
Which gas exist in the highest concentration in the earths present atmosphere?
Nitrogen is about 79% of the Earth's atmosphere.
What gas was not found in earths early atmosphere but was produced by photosynthesis?
Carbon dioxide
What does gas do to some scientist think was missing from earths early atmosphere?
oxygen
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 is the most abundant gas in Earths present day atmosphere?
Nitrogen is the most abundant gas but the interesting thing about it, is that we can not use it in the gaseous state.
What greenhouse gas used to make up most of earths early atmosphere?
Carbon dioxide used to make up most of Earth's early atmosphere.
What is earths atmosphere is an example of what solution?
gas-gas
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.
