You will die
Earth's atmosphere is about 21% oxygen by volume (for dry air).
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.
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.
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.
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.
we would be dead
If the sun exploded it would not give us oxygen; it would simply vaporize Earth.
no air and no oxygen
all human and animal activity would die
Humans would die, because plants make our oxygen
we well not get oxygen and all earth get die
we will die because there is no oxygen to breathe in
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.
The thick atmosphere has enough oxygen so than living things can happen.
if there is no plants humans cant get oxygen so naturally people cant exist on earth
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
These are elements in the periodic table. They also happen to make up the vast majority of earth's atmosphere.
