How long can aerosols and ash that erupt from a volcano stay in the upper atmosphere?
aerosols and ash can stay on the atmosphere for months or years.
How long was the surface of the earth molten?
The earth was in molten state for approximately 0.8-1 billion years.
What type of atmosphere is present when earth is formed?
The atmosphere of Earth has changed since its formation. When the Earth formed 4.6 billion years ago, it was a molten ball of rock with an atmosphere of hydrogen and helium. This atmosphere was blown away by the solar winds because there was no magnetic field to protect the Earth. After the Earth cooled, volcanoes released gases such as water vapour, ammonia and carbon dioxide. The ammonia was broken down into nitrogen and hydrogen by sunlight. Eventually, the evolution of cyanobacteria released oxygen into the atmosphere, which began to have a similar composition to the modern atmosphere.
How do scientists know chlorine and bromine effect the ozone layer?
Scientists have performed experiments under conditions that they believe replicate the conditions in the upper atmosphere where the presence of chlorine and bromine radicals (created when solar radiation breaks them free from the molecules they were once part of) and ice crystals catalyzes a more rapid decomposition of ozone (O3) back to simple oxygen molecules (O2). In all honesty, scientists don't KNOW that Cl and Br actually do that in the upper atmosphere, but the evidence is very strong based on existing research. Theoretically, the halogenated hydrocarbons that contain these atoms are very stable and can persist long enough remain intact for the years it may take them to diffuse into the upper atmosphere and be decomposed as theorized in the experiments.
How does respiration affect the amount of carbon dioxide in the atmosphere?
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.

What kind of pyroclastic marterial can reach the upper atmosphere and circle the earth for years?
volcani ash

What happenes to global temp for several years after a eruptions?
In an eruption that places alot of smoke and ash into the upper atmosphere, light reflects off the smog particles and is prevented from entering the lower atmosphere, the amount of light reflected is dependant on the amount of suspended particulate. In a major eruption the ash can spread out far enough and thickly enough to affect global temperatures, cooling the entire planet until the smog settles and dissipates.
What has Mars lost that Earth may too?
Mars has lost its molten core (and as a result, it's magnetic field), its liquid water, and most of its atmosphere. These may someday happen to Earth, though hopefully not for billions of years.

What were the gases in the air 4.5 billion years ago?
4.5 billion years ago the earth was a molten ball surrounded by hydrogen and helium.
Has the number of subatomic particles changed?
No, from 80 years.
Was the earth's atmosphere always the same?
No, actually it took a period of about 2.5 billion years for the atmosphere to be were it is today.
What was Ancient Egypt's atmosphere like?
The atmosphere of the planet is not noticeably different now to how it was 4000 years ago.
What element transformed carbon dioxide atmosphere a billion years ago to what you breathe?
Oxygen is the element that transformed Carbon Dioxide atmosphere a billion years ago to what you breathe.
