Nitrogen gas makes up about 78% of Earth's atmosphere today. However, human activities have altered the nitrogen cycle by increasing the amount of reactive nitrogen in the environment through processes like fertilizer use and fossil fuel combustion, which can lead to environmental issues like air and water pollution.
What else can I help you with?
How was earths early atmosphere first changed?
Earth's early atmosphere was first changed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. This led to the formation of oceans and the gradual accumulation of oxygen through photosynthesis by early organisms like cyanobacteria. This oxygenation process transformed the atmosphere to one more similar to the one we have today.
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.
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.
Earths original atmosphere was mad of gases similar to those?
to those found in volcanic eruptions today, such as water vapor, carbon dioxide, and nitrogen. These gases were likely released from the Earth's interior through volcanic activity. Over time, the atmosphere changed as oxygen levels rose due to photosynthetic organisms.
What gases make up the earths atmosphere today?
The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases, such as argon, carbon dioxide, and trace amounts of other gases, make up the remaining composition.
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.
How was earths early atmosphere first changed?
Earth's early atmosphere was first changed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. This led to the formation of oceans and the gradual accumulation of oxygen through photosynthesis by early organisms like cyanobacteria.

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.
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 did the earths atmosphere change composition to become todays nitrogen and oxygen atmosphere?
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability

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.
What percentage of nitrogen is in the air today?
Approximately 78% of the Earth's atmosphere is composed of nitrogen.
Was the atmosphere of the earth always mostly nitrogen and oxygen?
No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
What gases make up the earths atmosphere today?
The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases, such as argon, carbon dioxide, and trace amounts of other gases, make up the remaining composition.
