What gas was present in earths primitive atmosphere?
The primary gases in Earth's primitive atmosphere were likely hydrogen, helium, methane, ammonia, and water vapor. Over time, these gases were likely transformed by geological and biological processes into the current composition of the atmosphere.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
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.
What would earths atmosphere likely consist mostly of without the presence of life?
If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
Which was least likely to have been a component of earths atmosphere before life began?
Oxygen was least likely to have been a component of Earth's atmosphere before life began. It was initially scarce, and the atmosphere was primarily made up of gases such as methane, ammonia, water vapor, and carbon dioxide. Oxygen started to accumulate in the atmosphere following the emergence of photosynthetic organisms.
Extremely high temperatures most likely found in this part of earths atmosphere?
Thermosphere

What era is when earths atmosphere formed?
The Earth's atmosphere began forming approximately 4.5 billion years ago during the Hadean Eon, following the planet's formation. This initial atmosphere was likely composed of gases released from volcanic activity and impacts from comets and asteroids.
Was least likely to have been a component of Earths atmosphere before life began?
oxygen
Was the first tornado in tornado alley?
Most likely not. Tornadoes have probably been around since Earth had the same basic atmosphere of oxygen and nitrogen, perhaps even in Earth's primordial atmosphere, long before the tornado alley we know today even existed. Most people say yes and some say no.
What era did earths atmosphere form in?
Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.
A colorless oderless gas that is found in trace amounts in earths atmosphere?
The gas you are referring to is likely nitrogen. Nitrogen is the most abundant component of Earth's atmosphere, making up approximately 78% of the air we breathe. It is colorless, odorless, and mostly inert.
Where was the first black hole?
The very first black hole is believed to have likely accompanied events in the early universe where matter first formed from the tremendous energies from the big bang; such are referred to as primordial black holes. There isn't direct evidence for them nor details about their location but theoretical modelling suggests they exist. The first strong black hole candidate discovered from Earth around 1972 was in Cygnus X-1, which is an X-ray binary source; verification included trips to the upper atmosphere and observation outside the atmosphere.
