A determination of the composition of the Earth's atmosphere obtained from on-board radiometer measurements of the spectra emitted from the bow shock layer of a high-speed entry probe is reported herein. The N 2, O 2, CO 2 and noble gas concentrations in the Earth's atmosphere were ...
Climatic conditions are delicately adjusted to the composition of the Earth"s atmosphere. If there were a change in the atmosphere--for example, in the relative proportions of atmosphere gases--the climate would probably change also. A slight increase in water vapor, for instance, would increase...
The Earth's atmosphere is a complex and vital component that plays a crucial role in supporting life on our planet It is a thin layer of gases that surrounds the Earth, protecting us and influencing various aspects of our environment and climate The composition of the Earth's atmosphere is ...
Why does the atmospheric greenhouse effect make the composition of Earth's atmosphere so different from that of Venus? The answer lies in Earth's location in the solar system. Consider early Earth and early Venus, each having about the same mass, but with Venus orbiting somewhat closer to the...
The oxygenation of Earth’s atmosphere by photosynthesizing cyanobacteria is widely regarded as one of the most influential processes in Earth’s 4.5-billion-year history. Not only did the accumulation of free O2 directly enable the evolution of modern animals1, but it also fundamentally changed Ea...
The Origin of Earth’s Atmosphere Paragraph 1:In order to understand the origin of Earth's atmosphere, we must go back to the earliest days of the solar system, before the planets themselves were formed from a disk of rocky material spinning around the young Sun. This material gradually coal...
MR. A. PARKER (Jour. Chem. Soc., April, 1914) in a study of the inflammation of mixtures of methane with oxygen and nitrogen, has found that inflammation can be brought about more easily in mixtures containing nitrogen than in pure oxygen. In fact, the mixture which requires for ignition...

How and when did the atmosphere change?The answer to this riddle lies in the metabolic activity of early photosynthetic life-forms that slowly but surely transformed the chemical composition of Earth’s atmosphere. Some of these early organisms were photosynthetic relatives of modern cyanobacteria (...
