Without life, Earth's atmosphere would lack oxygen, as it is primarily produced by photosynthetic organisms. The composition of gases would likely be primarily nitrogen and carbon dioxide, similar to the early Earth's atmosphere. There would also be fewer greenhouse gases, leading to lower temperatures on the planet.
What else can I help you with?
Earths water land and atmosphere where life exists is known as?
Biosphere.
Which element in earths atmosphere is essential for human life?
Oxygen is the most essential element in Earth's atmosphere for human life. It is needed for cellular respiration, the process by which our cells generate energy. Without oxygen, humans would not be able to survive.
What would Earth's atmosphere be like today if life had not evolved on Earth?
It might be similar to the atmosphere on Venus, where the oxygen has combined with surface rocks and as carbon dioxide. On Earth, plants remove carbon dioxide and increase the level of free oxygen that supports animal life. This atmosphere also reduces ultraviolet radiation, which also affects the level of gases.
Why is the Earths atmosphere needed for life?
The Earth's atmosphere is necessary for life because it contains oxygen for respiration, regulates temperature, protects against harmful rays from the sun, and provides the air we breathe. Without the atmosphere, conditions on Earth would be too extreme for life to exist.
What would earths atmosphere likely consist mostly of without the presence of life?
If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
How would earths atmosphere be different if organisms capable of photosynthesis not evolved?
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
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 is main cause of earths atmosphere changing over time to support life?
Green plants evolved adding oxygen to the atmosphere.
How does the the earths atmosphere support life?
Bc its cool
Why is earths atmosphere good for life?
it bounce back the UV radiations
Earths water land and atmosphere where life exists is known as?
Biosphere.
Will the earths moon ever have life form living on it?
no that is unlikely because the moon does not have enough gravitational pull to hod an atmosphere, so the there would would not be any types of gasses available for life. =D
Why did the earth's atmosphere change after it was first formed?
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.
What do you think earth atmosphere would be like today if life had not evolved one earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
