What were two of the dominant gases in Earth's second atmosphere?
Oxygen and nitrogen were two dominant gases in Earth's second atmosphere. Oxygen levels were much lower than they are today, while nitrogen constituted a significant portion of the atmosphere even then.
What are the main gases in earths atmosphere today?
The main gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). Other important gases include argon, carbon dioxide, and trace amounts of water vapor, methane, and ozone.
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 gases were present in earths today atmosphere?
The main gases present in Earth's atmosphere today are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and carbon dioxide (about 0.04%). Other gases such as water vapor, methane, and trace amounts of other gases are also present.
How was oxygen added to the earths atmosphere?
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
How is Biogeochemistry used today?
biogeochemistry is used by earths atmosphere
What is wrong with earths atmosphere today?
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
When did the chemical composition of earths atmosphere reach that of today?
It reach when your mother had sucked your dads dick
What are the two gases that existed in earths earlier atmosphere?
The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter today.
What were two of the dominant gases in Earth's second atmosphere?
Oxygen and nitrogen were two dominant gases in Earth's second atmosphere. Oxygen levels were much lower than they are today, while nitrogen constituted a significant portion of the atmosphere even then.
What is a gas that was probably abundant in earths atmosphere 3.6 billion years ago and is still abundant today?
Oxygen
How has the earths atmosphere changed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
What are the main gases in earths atmosphere today?
The main gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). Other important gases include argon, carbon dioxide, and trace amounts of water vapor, methane, and ozone.
What do you think earths atmosphere would be like today if life had not evolved on earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
Why earths atmosphere today contains more oxygen than earth atmosphere?
The increased oxygen levels in Earth's atmosphere today compared to earlier in its history are due to the evolution and proliferation of photosynthetic organisms like plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, gradually increasing its concentration in the atmosphere over millions of years.
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.

What is the most dominant language spoken in the world today?
The most dominant language spoken in the world today is English.
