well sir, you see balls are very harry. that is all.
Helium contributed least to the early composition of the atmosphere, as it is relatively rare and not produced in significant quantities by natural processes on Earth.
The early atmosphere changed due to processes such as volcanic activity, which released gases like water vapor, carbon dioxide, and methane. Over time, these gases were modified by the activity of early life forms that produced oxygen through photosynthesis. This resulted in the gradual transformation of the atmosphere into one more similar to what we have today.
The gases in Earth's early atmosphere likely came from volcanic activity, outgassing from the Earth's interior, and impacts by comets and asteroids. These processes released gases such as water vapor, carbon dioxide, methane, and ammonia into the atmosphere.

The atmosphere on Mars is believed to have formed through a combination of volcanic activity and impacts from comets and asteroids early in its history. Over time, the atmosphere has thinned due to factors such as the loss of magnetic field and solar wind erosion. This has led to the current thin and predominantly carbon dioxide-based atmosphere on Mars.
EARLY ATMOSPHERE have humidity
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.
pollution
i have absoulutely no idea whatsoever check a different website p.s. i love twilight
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.

The layers of atmosphere are different according to their functions. They are at different heights.
Nitrogen and Oxygen.
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.
