What else can I help you with?
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.
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which of these developed?
green plants / algae
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?
The water vapor in the early atmosphere of Earth likely condensed and fell as rain, contributing to the formation of the oceans. This process, known as the "water cycle," involves the continuous movement of water between the atmosphere, land, and oceans through processes like evaporation, condensation, and precipitation. Over time, the oceans became the primary reservoir for water on Earth, where it remains today.
What does gas do to some scientist think was missing from earths early atmosphere?
oxygen
What gas do scientist think was missing from earths early atmosphere?
Methane gas
Which important element was missing in earths early atmosohere?
Oxygen was the important element missing in Earth's early atmosphere. It was only produced later by photosynthetic organisms.
What scientist think was missing from the early atmosphere?
Oxygen was the missing thing was.
What gas was lacking from earths early atmosphere in the early precambrian?
oxygen
What gas was not a part of earths early atmosphere?
nitrogen
What gas was not part of early earths atmosphere?
oxygen
What gas produced by plants and algae was missing from earths early atmosphere?
Oxygen gas was thought to be missing. Other compounds such as nitrogen and its oxides, carbon dioxide, methane, ammonia, hydrogen, and hydrogen sulfide were believed to be released by volcanos-- they were there.Source: AP Biology textbook, ed.8, Pearson
Was the earths early atmosphere made up of mostly oxygen?
no
What was the major contributor of oxygen to earths early atmosphere?
photosynthsis
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
