Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
What prediction do scientists make about how the composition of earths atmosphere will change in the future?
Scientists predict that the composition of Earth's atmosphere will change in the future due to human activities such as burning fossil fuels, leading to an increase in greenhouse gases like carbon dioxide. This is expected to cause global warming and climate change, with potential negative impacts on the planet's ecosystems and weather patterns.
What is the primary (most abundant) gas in the Earths atmosphere?
The primary gas in Earth's atmosphere is nitrogen, accounting for about 78% of the total atmospheric composition.
Where did the nitrogen come from in earths atmophere?
Nitrogen in Earth's atmosphere is believed to have come from volcanic outgassing billions of years ago, as well as from the breakdown of ammonia in the early atmosphere through photochemical reactions. This nitrogen has been recycled through various natural processes, such as plant respiration and decomposition, contributing to the stable composition of nitrogen in the atmosphere.
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
How does the composition of Earths atmosphere different from the composition of the atmosphere of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
Why is chemical composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
How does the composition of earths atmosphere differ from the composition of the atmospheres of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
Do xrays get through earths atmosphere?
no.
How the composition of gases changes as you travel up through the earths atmosphere?
As you go higher in the atmosphere the gases start to compose or join together which causes them to change since there is mixture of more than one gas. Sometimes they form a different element when certain gases form.
How do tsunamis change the earths atmosphere?
cuz they can
What is true about earths atmosphere?
it will always change
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?

Does infrared get through the earths atmosphere?
yes.
How did the earths atmosphere change composition to become todays nitrogen and oxygen atmosphere?
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability
When did the chemical composition of earths atmosphere reach that of today?
It reach when your mother had sucked your dads dick
