How did earths atmosphere change during precambrian time?
The amount of oxygen increased greatly
Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
What affect does living organisms have on the composition of earths atmosphere?
The amount of Oxygen started to increase as more plants and animals appeared. The plants took in Carbon dioxide and gave out Oxygen. So, overtime the amount of Carbon dioxode (which was high) decreased, and oxygen increased.
Which gases have increased and decreased from the original atmosphere?
Since the original atmosphere, the gases which have decreased are water vapour and carbon dioxide and the gases which have increased are nitrogen, oxygen
How did oxygen become a part of the earths atmosphere and what did this increase in oxygen levels allow?
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes

Has the amount of oxygen released into the atmosphere increased in recent years?
The amount of oxygen released into the atmosphere has not noticeably increased in recent years. The amount of oxygen (O2) in the atmosphere is about 21%. It is part of the earth's oxygen cycle, the main driver of which is photosynthesis. Vegetation removes carbon dioxide (CO2) from the atmosphere, releases the oxygen (O2) and stores the carbon (C).

What is the amount of oxygen in the atmosphere?
Air is 20.5 percent oxygen.
Which gases have increased and decreased from the original atmosphere?
Since the original atmosphere, the gases which have decreased are water vapour and carbon dioxide and the gases which have increased are nitrogen, oxygen
What planets do not have oxygen?
Only Earth has any significant amount of oxygen in its atmosphere.
Earth's atmosphere is unique because it contains a significant amount of?
Oxygen! ^_^
Historically have there been any changes to the proportion of oxygen in air?
When the earth was first made, there was very little oxygen, the atmosphere was mainly co2, ch4, h2o and other gasses. Then, after life developed, some of the bacteria started to produce o2. This dramatically increased the amount in the atmosphere. since then there have been constant fluctuations as with many of the gasses in our atmosphere like carbon dioxide.
Atmospheric oxygen increased after the evolution of photosynthetic prokaryotes?
There is an increased amount of oxygen after completion of the photosynthetic process.
Which major physical change could be attributed to photosynthesis?
Photosynthesis drastically increased the oxygen content of the atmosphere.
How did Earth change about 2.5 billion years ago when many organisms began using photosynthesis to make food?
The amount of oxygen in the atmosphere increased.Until then carbon dioxide had been present in huge quantities in the atmosphere, while oxygen would have been extremely rare. Photosynthesis uses up carbon dioxide and releases oxygen so the proportion of oxygen would have increased dramatically, paving the way for oxygen-breathing life-forms.
