What gas is the largest component of earths present atmosphere?
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
What is the approximate percent of oxygen by volume present earths lower atmosphere?
Oxygen makes up about 21% of Earth's lower atmosphere by volume.
What is the approximate percent of oxygen by volume present in earths lower atmosphere?
The approximate percent of oxygen in Earth's lower atmosphere is around 20.95% by volume.
WHAT IS THEAPPROXIMANT PERCENT OF OXYGEN BY VOLUME PRESENT IN EARTHS LOWER ATMOSPHERE?
The approximate percentage of oxygen in Earth's lower atmosphere is around 21% by volume.
Where did the earths present atmosphere originate?
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
What element in earths atmosphere was not present in the far past but is present now?
The element "Oxygen".
Which gas exist in the highest concentration in the earths present atmosphere?
Nitrogen is about 79% of the Earth's atmosphere.
What gas is the largest component of earths present atmosphere?

Which layer of the earths atmosphere protects the earth from the ultraviolet radiations of the sun?
Ozone layer protects us. It is present in the stratospheric region of atmosphere.
What layer of earths atmosphere would be considered good ozone?
There is good ozone and then there is bad ozone. Good ozone is present in the earth's atmosphere.
What is the approximate percent of oxygen by volume present earths lower atmosphere?
Oxygen makes up about 21% of Earth's lower atmosphere by volume.
What molecule was not present in early Earths reducing atmosphere?
Oxygen (O2) was not present in early Earth's reducing atmosphere. It only became abundant in the atmosphere due to the photosynthetic activity of cyanobacteria and other early organisms.
What is the approximate percent of oxygen by volume present in earths lower atmosphere?
The approximate percent of oxygen in Earth's lower atmosphere is around 20.95% by volume.
WHAT IS THEAPPROXIMANT PERCENT OF OXYGEN BY VOLUME PRESENT IN EARTHS LOWER ATMOSPHERE?
The approximate percentage of oxygen in Earth's lower atmosphere is around 21% by volume.

Does the density of the earths atmosphere increase with altitude or decrease?
The density of Earth's atmosphere decreases with altitude. As you move higher up in the atmosphere, there are fewer molecules of gases present, leading to lower density.
