Earth has more nitrogen than oxygen in its atmosphere because nitrogen is less reactive and more abundant in the Earth's crust. Nitrogen makes up about 78% of the atmosphere, while oxygen only makes up about 21%. This is due to the fact that oxygen is more reactive and is constantly being used up in chemical reactions, whereas nitrogen is more stable and remains in the atmosphere in larger quantities.
What else can I help you with?
Molecules of hydrogen escape from earth but molecules of oxygen and nitrogen are held to the surface why?
Hydrogen molecules are very light and have high velocities, which allows them to reach escape velocity and escape Earth's gravitational pull. On the other hand, oxygen and nitrogen molecules are heavier and have lower velocities, so they are more likely to be retained by Earth's gravity and stay within the atmosphere. Additionally, the interactions and composition of Earth's atmosphere play a role in retaining oxygen and nitrogen compared to hydrogen.
Is there more nitrogen or carbon dioxide in earth's atmosphere?
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
Which two gases make up 99 percent of the gases in the atmosphere which gas is more abundant?
I am looking for the exact same answer I know one of the gases should be oxygen
What substance does earth contain more of?
Nitrogen Well, Oxygen is the most abundant element on earth if you include the Air, Water and Land. Oxygen makes up 50% of the earth. But Nitrogen is contained most in the air (atmosphere), making 78% of the air.
What is the percent composition of gases that make up the Earth's atmosphere?
Earth's atmosphere is made up of 78-percent nitrogen, 21-percent oxygen, 0.93-percent argon, and 0.028-percent carbon dioxide. The earth's atmosphere is a very thin layer of these combined gases wrapped around the planet.
What is more abundant in the atmosphere oxygen or Nitrogen?
Nitrogen is more abundant in Earth's atmosphere, making up about 78% of the air. Oxygen makes up about 21% of the atmosphere.
What gas is more abundant nitrogen or oxygen?
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
Why is the atmosphere 78 percent nitrogen and only 21 percent oxygen?
There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen
Does the atmosphere have more nitrogen or oxygen in it?
The atmosphere contains more nitrogen than oxygen. Approximately 78% of the atmosphere is nitrogen, while oxygen makes up about 21%. The remaining 1% consists of other gases like argon, carbon dioxide, and trace gases.
Which makes up more of the atmosphere Nitrogen or Oxygen?
Nitrogen
Which planet's atmosphere is mostly nitrogen and oxygen?
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
Ninety nine percent of atmosphere is composed of what?
The nitrogen and oxygen in Earth's atmosphere together account for a speck more than 99% of it..
Why is there more nitrogen in the atmosphere than oxygen?
Nitrogen makes up about 78% of Earth's atmosphere compared to about 21% oxygen. This difference is due to the way these gases were trapped during Earth's formation and the chemical reactions that have taken place over billions of years. Nitrogen is less reactive than oxygen, so it has remained more abundant in our atmosphere.
What is the most abundant of nitrogen and oxygen?
Nitrogen is more abundant; our atmosphere is 78% Nitrogen.
Molecules of hydrogen escape from earth but molecules of oxygen and nitrogen are held to the surface why?
Hydrogen molecules are very light and have high velocities, which allows them to reach escape velocity and escape Earth's gravitational pull. On the other hand, oxygen and nitrogen molecules are heavier and have lower velocities, so they are more likely to be retained by Earth's gravity and stay within the atmosphere. Additionally, the interactions and composition of Earth's atmosphere play a role in retaining oxygen and nitrogen compared to hydrogen.
Before photosynthesis evolved was oxygen rare in Earth's atmosphere?
Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.
Why do we need more nitrogen then oxygen?
Nitrogen makes up about 78% of Earth's atmosphere, while oxygen makes up about 21%. Nitrogen is needed for vital biological processes such as building proteins and DNA. It is also crucial for the growth of plants and helps maintain the balance of gases in our atmosphere.
