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.
Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
What is earths Precambrian atmosphere?
The Earth's Precambrian atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. It lacked oxygen and had higher levels of greenhouse gases compared to the present atmosphere. This environment supported the evolution of early life forms such as bacteria and algae.
How has the earths atmosphere changed during the Precambrian time?
During the Precambrian time, the Earth's atmosphere lacked free oxygen, and the early atmosphere was likely composed of gases such as methane, ammonia, and carbon dioxide. Throughout the Precambrian, there were significant changes in atmospheric composition due to volcanic activity and the evolution of photosynthetic organisms that contributed oxygen to the atmosphere.

How did the addition of oxygen to earths atmosphere affect the evolution of life?
it made it possible 4 it to be plants animals and human life
How do geologists think earths atmosphere formed?

What is the earths second layer of earths atmosphere?

Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
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.
What is the layer of earths atmosphere farthest away from earths surface?
Thermosphere, it is also the atmosphere with the highest temperatures.
What do we call pieces of stone the enter the earths atmosphere?
Meteoritesis what we call stones that enter the earths atmosphere.
What is the atmosphere of the earths moon?
There is no atmosphere on the Earth's moon.
What the Earth's atmosphere made of?
