If the Nitrogen and Oxygen were not replaced in the atmosphere how long would our present supply of these gases last?
If nitrogen and oxygen in the atmosphere were not replenished, they would last a very long time due to their stability and abundance. Nitrogen makes up about 78% of the atmosphere, while oxygen constitutes about 21%. The primary sources of oxygen, such as photosynthesis from plants, are crucial for its continuous supply; without these processes, oxygen levels would gradually decrease over centuries. However, nitrogen is inert and doesn't get consumed in significant amounts, meaning it could theoretically last indefinitely without replacements.
What else can I help you with?
Atmosphere has low air pressure and is mostly carbon dioxide?
The low air pressure in the atmosphere is due to the limited amount of gases present, including mostly nitrogen and oxygen. While there is carbon dioxide in the atmosphere, it makes up a small percentage compared to nitrogen and oxygen.
How much of the earths atmosphere is made up of nitrogen and oxygen?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Name the gases present in the upper atmosphere?
The gases present in the upper atmosphere include oxygen, nitrogen, argon, and trace amounts of carbon dioxide, helium, and hydrogen.
What is the atmosphere mainly made up of?
The Earth's atmosphere is mainly composed of nitrogen (about 78%) and oxygen (about 21%). Other gases present include argon, carbon dioxide, and traces of other gases like helium and methane. Water vapor is also an important component of the atmosphere.
Which planet's atmosphere is 78 percent nitrogen?
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
What system includes oxygen nitrogen and ozone?
The Earth's atmosphere includes oxygen, nitrogen, and ozone. Nitrogen makes up about 78% of the atmosphere, oxygen makes up about 21%, and ozone is present in the stratosphere as a protective layer against ultraviolet radiation.
What is two gases that present on earth?
The two most abundant gases on Earth are nitrogen and oxygen.
What is 99 percent of the atmosphere is made up of either oxygen or?
Nitrogen. Oxygen makes up approximately 21% of the Earth's atmosphere, while nitrogen makes up about 78%. Together, they account for the vast majority of the gases present in the atmosphere.
How much oxygen is present in air?
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
What are he two main components of the atmosphere?
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
If the nitrogen and oxygen were not replaced in the atmosphere how long would the present supply of gases last?
The current supply of nitrogen and oxygen in Earth's atmosphere would last indefinitely as these gases are continuously recycled through natural processes like photosynthesis, respiration, and nitrogen fixation. These processes ensure a stable balance of gases in the atmosphere.
What is the most abundant gas in our atmosphere oxygen hydrogen nitrogen water?
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is the second most abundant gas, at around 21%. Hydrogen is present in very small amounts, and water vapor is a variable component of the atmosphere.
What are the two most abundant compounds in our present atmosphere?
The two most abundant compounds in Earth's atmosphere are nitrogen gas (N2) and oxygen gas (O2). Nitrogen makes up about 78% of the atmosphere, while oxygen accounts for roughly 21%.
Does nitrogen dilute the oxygen in Earth's atmosphere?
No, nitrogen does not dilute the oxygen in Earth's atmosphere. Nitrogen and oxygen are the two main components of Earth's atmosphere, with nitrogen making up about 78% and oxygen about 21%. They coexist in the atmosphere without one diluting the other.
What gas is more abundant nitrogen or oxygen?
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
What two chemical elements make up most of Earth's atmosphere?
99% of the atmosphere is nitrogen (78%) and oxygen (21%).
What is the mixture of mostly nitrogen and oxygen?
Air
