Earth 's atmosphere protects us from meteors, most of which burn up before they can strike the surface. Nitrogen and Oxygen are the predominant gases in the atmosphere, accounting for about 99 percent of dry air. While 1 percent is mixture of all other gases make up the remaining 1 percent.
Composition of Atmosphere From the earth’s surface upwards to an altitude of about 80 km, the chemical composition of the atmosphere is highly uniform throughout in terms of the proportions of its component gases. In the uppermost reaches the atmosphere is charged with subatomic particles.
The study of the structure of the earth focuses on its layered structure, and the variations in the density and temperature, at various depths. The shape of the earth is that of a spheroid with mean equatorial radius of 6378-388 km. and polar radius of 6356912 km. concisely speaking, the earth is a globe having a radius of 6371 kilometers.Composition of the atmosphere Except for water vapor, whose atmospheric abundance varies from practically zero up to 4%, the fractions of the major atmospheric components N 2, O 2, and Ar are remarkably uniform below about 100 km.The composition of the atmosphere has changed since the Earth was formed 4.5 billion years ago. Natural processes and human activity have changed the atmosphere, and continue to change it today.
Generally, atmosphere extends up to about 1600 km from the earth’s surface. However, 99 % of the total mass of the atmosphere is confined to the height of 32 km from the earth’s surface. Composition of the atmosphere. The atmosphere is made up of different gases, water vapour and dust particles.Read More
Some known rocky planets with substantial atmosphere such as Venus, Mars and Earth has a very different composition of atmospheric gas. These planets experienced very different condition that causes the formation of current atmosphere.Read More

Then, the second atmosphere of the Earth was formed from the out gassing that can evaporate such as water vapour, carbon monoxide, methane, ammonia, nitrogen, carbon dioxide, hydrochloride acid and sulphur. It is still no free oxygen.Read More
Early composition. The most critical parameter pertaining to the chemical composition of an atmosphere is its level of oxidation or reduction. At one end of the scale, an atmosphere rich in molecular oxygen (O 2)—like Earth’s present atmosphere—is termed highly oxidizing, while one containing molecular hydrogen (H 2) is termed reducing.These gases themselves need not be present.Read More
Composition and Stratification of the AtmosphereA1. Which three gases constitute most of the earth’s atmosphere? A2. What range of altitudes constitute the troposphere? the stratosphere? A3. Describe the stratification of the atmosphere. Consider the basis on which stratification is achieved, and the names, features, and predominant chemical species and chemical process which occur in each.Read More
The Atmosphere is a transparent envelope of gases and suspended particles that surround the Earth. Without Chemical processes involving several of the atmospheric gases, life could not exist. Even the physical processes that operate in the atmosphere are of vital importance because they are responsible for the Earth's varied climates. The Atmosphere is composed almost entirely of Oxygen and.Read More
Geology deals with the composition of Earth materials, Earth structures, and Earth processes. It is also concerned with the organisms of the planet and how the planet has changed over time. Geologists search for fuels and minerals, study natural hazards, and work to protect Earth's environment Meteorology is the study of the atmosphere and how processes in the atmosphere determine Earth's.Read More
What is the atmospheric composition of Earth? Earth’s atmospheric composition is detailed with the dry air of nitrogen which comprises 78% of the earth’s atmosphere, oxygen is 20%, 0.9% argon and 1.1% other gases. Other gases’ include carbon dioxide, helium and hydrogen. Every planet has its own composition of atmospheric gases. When you chose the atmosphere and geography assignment help.Read More
Atmospheric composition is an essential part of the Earth System, as gases and aerosols directly affect our well-being and interact with the radiation that drives our climate. Paving the way for the future GMES Atmospheric Service, MACC combines computer model simulations with world-wide observations to monitor the composition of the Earth's atmosphere and predict regional air quality. From.Read More
