What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.

Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?
Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.
What major change occurred in the atmosphere during the precambrian?
During the Precambrian period, significant changes occurred in the atmosphere. Early in the period, the atmosphere was primarily composed of gases like methane, ammonia, and carbon dioxide with little to no oxygen. But over time, due to the emergence of photosynthetic bacteria, oxygen levels began to rise, leading to the development of an oxygen-rich atmosphere by the end of the Precambrian. This rise in oxygen was a major milestone in Earth's history, paving the way for the evolution of complex multicellular life forms.
What is is earths evolution?
The most popular scientific theory states that earth was once a Porto planet, a planet that is like a baby. a large asteroid [left overs from the sun] soon gained gravity that pulled more asteroids towards it. in a few million years, the large asteroid will become red and be filled with lava. volcanoes erupted that formed clouds with water then water filled today's ocean. the rest of the volcanoes made large islands that became Pangaea then Pangaea becomes today's continents. of course earth developed an atmosphere then clouds formed. the first animal was a bacterial that released methane in to the atmosphere. later oxygen releasing Bacterial developed and killed the methane releasing bacterial. then fish evolved, then land animals [small] then dinosaurs, then mammals, the probably Porto humans or early humanly creatures, then homosepicans, then caveman, then today's humans.
Wegener's theory that the continents slowly moved over earths surface became known as?
Wegener's theory that the continents slowly moved over Earth's surface became known as the theory of continental drift.
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

How does the study of fossils represent the evolution of species over geological time?
The study of fossils represent the evolution of species by the time period between when they became fossils and what the ancestory line is
What molecule was not present in early Earths reducing atmosphere?
Oxygen (O2) was not present in early Earth's reducing atmosphere. It only became abundant in the atmosphere due to the photosynthetic activity of cyanobacteria and other early organisms.
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
What Would Happen If More Of The Suns Heat Became More Trapped in Earths Atmosphere and less heat was released in space?
The Earth would start to heat up and the ocean would evaporate.
How evolution affects you?
That's how the human race became what it is.
What is a form of macro evolution?
Macro evolution is just speciation, so you are a form of macro evolution. We and the chimpanzees have a common ancestor that we split from about 6 million years ago. We became Homo sapiensand they became Pan troglodytes.
What is the evolution of the fish?
Supposedly, mollusks or such became fish, and then fish became amphibians to become lizards, or vice-versa.
When did meteorites form within the solar system?
probably a Little bit after the sun formed. the sun gravity pulled dust into orbit and the dust clumped to geather and some became bigger to form proto planets but others stayed the same and became asteroid NOT a meteorite a .meteorite is in earths atmosphere a asteroid is in space. did this help?
Who developed the ideas that became known as the theory of evolution by natural selection?
The answer is: Darwin
What planet lost its atmosphere and became a barren wasteland?
Mercury
Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
