What is the approximate percentage of oxygen in the atmosphere?
Earth's atmosphere is about 21% oxygen by volume (for dry air).
Is oxygen always omnipresent on Earth?
Oxygen is not omnipresent on Earth; it makes up about 21% of the Earth's atmosphere. It is produced through processes like photosynthesis by plants and organisms in the oceans. Without these processes, the levels of oxygen on Earth would gradually decline.
What would happen to the oxygen content of air?
If all humans suddenly disappeared from Earth, the oxygen content of the atmosphere would gradually increase due to the lack of human respiration and combustion processes. This could potentially lead to a temporary surge in oxygen levels until natural processes balance out the concentration.
What will happen if all the oxygen disappear?
If all the oxygen were to disappear, most life on Earth would perish within minutes. Oxygen is crucial for cellular respiration in most organisms, so a lack of it would lead to catastrophic consequences such as widespread death, ecosystem collapse, and the eventual extinction of many species.
Is oxygen manmade?
No. Earth's oxygen is provided by plants. Humans need oxygen to live, so we could not have been there before there was oxygen, so we could not have made the oxygen.
What would happen if there is no oxygen in earth?
we would be dead
What would happen if the sun exploded and released a ton of oxygen into earth?
If the sun exploded it would not give us oxygen; it would simply vaporize Earth.
What sorts of things that happen in space affect us on Earth?
no air and no oxygen
What would happen to the earth if there is no oxygen?
all human and animal activity would die
What could happen to earth if there were no plants?
Humans would die, because plants make our oxygen
What do you think would happen to living thing if there were no trees?
we well not get oxygen and all earth get die
What would happen to life on earth in plants take inthe same amount of oxygen as they gave out during the day?
we will die because there is no oxygen to breathe in
What will happen when there will be no oxygen in earth?
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive as oxygen is essential for respiration. Without oxygen, aerobic organisms would suffocate and eventually die. The atmosphere would likely become unbreathable, leading to widespread extinction of life.
How can earth sustain life?
The thick atmosphere has enough oxygen so than living things can happen.
What happen to humans if no plants?
if there is no plants humans cant get oxygen so naturally people cant exist on earth
Effects of no oxygen on earth?
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
How are oxygen and nitrogen categorized?
These are elements in the periodic table. They also happen to make up the vast majority of earth's atmosphere.
