How did earths atmosphere change during precambrian time?
The amount of oxygen increased greatly
Which gas would most likely be found in the greatest amount in the bubbles?
oxygen
Which element found in both biotite mica and muscovite mica makes up the greatest percent by volume of earths crust?
oxygen
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.
What are the different layers of earth atmosphere?
The four layers that constitute the earths atmosphere in order from space to the earths surface are as follows: Inosphere (aka. Aurora) @ 350km, Mesosphere @ 90-350km, Stratosphere @ 50-90km, and Troposhere @18-50km. It's composition is 79% Nitrogen, 20% Oxygen, and 1% other gases.
Which of the earths layers has the most air?
The Crust has the most oxygen in it

What atom is found in the greatest amount in the human body?
oxygen
What would happen to animals if the amount of oxygen the earths atmosphere decreased?
youll die
Which gas would most likely be found in the greatest amount in the bubbles?
oxygen
Is it true the greatest amount of gas in the air is oxygen?
No. If we look at the composition of gases in the atmosphere, the greatest amount of gas is nitrogen- 78%. Oxygen is 21% in the atmosphere. remaining 1% is carbon dioxide, carbon monoxide etc.
Which element found in both biotite mica and muscovite mica makes up the greatest percent by volume of earths crust?
oxygen
Do plants give off the greatest amount of oxygen in summer day or night?
They give off more oxygen during the day.

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.
Is the greatest amount of gas in the air oxygen?
No it isn't. It is Nitrogen, which makes up 70% of the air we breathe.
