What factor contributed to the formation of earths early atmosphere?
energy from the sun,lightening,earths heat triggered chemical reaction for the early gases of the earth combined
How did volcanoes affect the early earths atmosphere?
Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.
How do geologists use rocks to prove the existence of oxygen in earths early atmosphere?
They look at the mineral composition of the rocks. There are some minerals that can only form in the presence of oxygen.
What happened to the water vapour that was in the early atmosphere?
What happened to all the water vapour in the early atmosphere
Which gas is thought to have been missing from early Earth's early atmosphere?
Carbon doixide
Oparin's hypothesis suggested that early Earth's atmosphere lacked what?
oxygen
Oparin's hypothesis suggested that early Earth's atmosphere lacked?
Oxygen
What gases did Oparin think were in the earth's early atmosphere?
( h2; ch4; nh3)
Was there oxygen in the early earths atmosphere?
yes
What gases were in Oparin's hypothesis?
Oparin suggested that the atmosphere of early Earth was composed of methane, ammonia, hydrogen, and water vapor. He also thought lightning and energy from the sun helped these gases to combine, he thought life was made from that.
What gas was lacking from earths early atmosphere in the early precambrian?
oxygen
What is true of Oparin and Haldane's theory?
One thing that is true in the Oparin - Haldane theory is that the early earth used to consist of an atmosphere which carried ammonia and water vapor. This is true because that is a condition that allows biological polymers to thrive.
What gas was a thought by Oparin to be part of the early Earth's atmosphere?
He thought that the early Earth's atmosphere contained ammonia, NH3; hydrogen gas, H2; water vapor, H2o; and compounds made of hydrogen and carbon, such as, CH4.
What gas was not part of early earths atmosphere?
oxygen
What gas was not a part of earths early atmosphere?
nitrogen
What molecule was not present in early Earths reducing atmosphere?
nitrogen
Earths early atmosphere was changed dramatically by the evolution of?
photosynthesis
