What would happen to the amount of oxygen in Earth and atmosphere if half the trees on Earth were cut down Why?
Cutting down half of the trees on Earth would reduce the amount of oxygen produced through photosynthesis, potentially leading to a decrease in atmospheric oxygen levels. However, the impact on overall oxygen levels would be mitigated by the fact that trees make up only a portion of the Earth's oxygen-producing plants. Other plants, as well as oceans and other sources, also contribute to the atmospheric oxygen supply.
What percentage of the Earth's atmosphere is composed of oxygen?
About 21% of the Earth's atmosphere is composed of oxygen.
What percent of oxygen on the earth?

What is percentage of oxygen in earth planet?
The Earth's atmosphere is composed of about 21% oxygen. This oxygen is crucial for supporting life on Earth through processes like respiration and photosynthesis.
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
How can earth sustain life?
The thick atmosphere has enough oxygen so than living things can happen.
What will happen if there is no oxygen on earth?
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive. This is because oxygen is essential for cellular respiration, the process that generates energy for living organisms. Additionally, without oxygen, the ozone layer would also be unable to protect the Earth from harmful solar radiation.
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.
