What earth's atmosphere has been altered by the presence of life it's the atmosphere contains more than any other atmosphere?
The presence of life - in particular plants that are powered by photosynthesis - has lead to a significant amount of free oxygen into the atmosphere. On other known planets, most of the oxygen is tied up in solid oxides or carbon dioxide rather than as oxygen gas.
What does our atmosphere do that makes conditions on Earth suitable for life?
You have it wrong way round, the atmosphere of Earth was created by the life on Earth. 4000 million years ago the atmosphere had no oxygen and was full of CO2, Nitrogen and Methane. However life came into existence in this atmosphere and over time has altered the atmosphere to what we have today. Therefore the composition of the atmosphere would not appear to be critical to life.
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.
How did cyanobacteria change life on earth?
Cyanobacteria played a crucial role in changing the Earth's atmosphere by producing oxygen through photosynthesis billions of years ago. This event led to the oxygenation of the atmosphere, which enabled the evolution of more complex life forms and fundamentally altered the ecological balance on Earth.
How can a pond be altered by a dry season?
A pond community can be altered or changed by a dry season by having most of the water evaporated into the atmosphere thus removing the habitual need of the organisms living there.
How important is the atmosphere to life on earth?
Without the atmosphere, there would be no life on earth.
A life-form in the Precambrian time was?
One example of a life-form in the Precambrian time was cyanobacteria, which are ancient photosynthetic bacteria thought to be one of the earliest forms of life on Earth. Cyanobacteria played a crucial role in the Great Oxygenation Event by producing oxygen as a byproduct of photosynthesis, which significantly altered Earth's atmosphere.
What would happen if the Earth's Atmosphere was greatly altered?
We would die from the different gases and/or burn/freeze to death! :0
If the earth tip 1 degree either side will there still be life on earth?
yes but the fragments of the earths atmosphere will be altered so reaaly this is just a guess otherwise nothing will happen and whoever wrote this question is just plain stupid
What is the Precambrian atmosphere composed of?
The Precambrian atmosphere, which existed before the emergence of complex life on Earth, was primarily composed of nitrogen, carbon dioxide, and water vapor, with very little oxygen. During this era, volcanic outgassing contributed to the atmospheric composition, while the absence of significant photosynthetic life meant that oxygen levels remained low. It wasn't until the Great Oxygenation Event, around 2.4 billion years ago, that oxygen began to accumulate in the atmosphere due to the photosynthetic activity of cyanobacteria. This shift significantly altered the composition and chemistry of the atmosphere, paving the way for aerobic life forms to evolve.
How does earths atmosphere make condtions on earth suitable for living things?
You have that the wrong way round, LIVING things have changed Earth's atmosphere to make it suitable for them. When Earth first came into being, the atmosphere was NOT like it is now, it could not sustain the life that exists today. Over Geological time tiny bacterial organisms generated the Oxygen that we have in our air today, and altered the whole environment of the planed in doing so. Thus the driving factor is LIFE not the atmosphere.
How did stromatolites change the atmosphere of early earth?
Stromatolites, which are ancient microbial structures, played a crucial role in changing the atmosphere of early Earth by photosynthesizing and releasing oxygen as a byproduct. This oxygen accumulation in the atmosphere led to the Great Oxidation Event, which significantly altered the composition of the Earth's atmosphere from reducing to oxidizing.
