The original gases on Earth 4.6 billion years ago likely consisted of hydrogen, helium, methane, and ammonia. These gases were present during the planet's formation and early geological processes. Over time, the atmosphere evolved into what we know today through volcanic activity and biological processes.
What else can I help you with?
If the age of the Earth is 4.5 billion years and the half-life of 40K is 1.26 billion years what percent of the Earth's original amount of 40K remains today?
Approximately 25% of the Earth's original amount of 40K remains today, given that one half-life of 40K is 1.26 billion years. This means that half of the original amount decayed in 1.26 billion years, leaving behind the remaining 50%, which is now further decaying to reach 25% after 4.5 billion years.
Does the earth have 100 billion years?
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.
What happened to the earth 700 billion years ago?
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
Was the earth around 7 billion years ago?
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
Will Earth be disintegrated in 2 billion years?
It is unlikely that Earth will be disintegrated in exactly 2 billion years. However, in about 5 billion years, the sun will expand into a red giant, potentially reaching Earth's orbit and causing the planet's destruction.
What are the two deadly gases Four billion years ago the earth's atmosphere?
The two deadly gases present in Earth's atmosphere four billion years ago were methane and ammonia. These gases were toxic to early organisms and would have made the atmosphere hostile to life as we know it today.
What were the gases in the air 4.5 billion years ago?
4.5 billion years ago the earth was a molten ball surrounded by hydrogen and helium.
If the age of the Earth is 4.5 billion years and the half-life of 40K is 1.26 billion years what percent of the Earth's original amount of 40K remains today?
Approximately 25% of the Earth's original amount of 40K remains today, given that one half-life of 40K is 1.26 billion years. This means that half of the original amount decayed in 1.26 billion years, leaving behind the remaining 50%, which is now further decaying to reach 25% after 4.5 billion years.
The year of the formation of the Earth?
The Earth was formed about 4.57 billion years ago when a mass of particles and gases formed a rotating cloud that eventually concentrated into what we know call Earth.
What were the gases on earth 4.4 billion years ago?
4.4 billion years ago, Earth's atmosphere likely consisted of gases such as carbon dioxide, water vapor, nitrogen, and traces of methane and ammonia. There would have also been volcanic outgassing contributing to the composition of the atmosphere at that time.
Does the earth have 100 billion years?
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.
What happened to the earth 700 billion years ago?
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
What 4.6 billion years is to the earth?
It is just a fact that earth is 4.6 billion years old.
When will the earth turn 7 billion years old?
The Earth is currently 4.5 billion years, so in approximately 2.5 billion years time.
Did earth form 50 billion years ago or 5?
Earth formed approximately 4.5 billion years ago, not 50 billion years ago or 5 billion years ago. This age estimate is based on radiometric dating of meteorites and rocks on Earth.
Was the earth around 7 billion years ago?
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
Will Earth be disintegrated in 2 billion years?
It is unlikely that Earth will be disintegrated in exactly 2 billion years. However, in about 5 billion years, the sun will expand into a red giant, potentially reaching Earth's orbit and causing the planet's destruction.
