Composition Of Atmosphere Pdf

The air surrounding the earth is called the atmosphere. Insolation and Heat Balance of the Earth. Oxidation Some oxygen is produced when sunlight reacts with water vapor in the atmosphere. It also combines with several other elements and minerals to form different oxides such as the iron oxide, aluminium oxide and others. Because continuity is very essential.

Dust Particles Dust particles include sea salts, fine soil, smoke-soot, ash, pollen, dust and disintegrated particles of meteors. Oxygen occurs in several combinations and chemical forms. Notify me of new posts by email.

Composition of the Atmosphere

Dust and salt particles act as hygroscopic nuclei around which water vapour condenses to produce clouds. Finally, the atmosphere is a site for a large variety of complex photochemically initiated reactions involving both natural and anthropogenic substances. Integrate Learning With Test-Taking!

Summarize the structure and composition of our atmosphere. The atmosphere is composed of a mix of several different gases in differing amounts. Ozone in the upper atmosphere filters out the ultraviolet light below about nm that is destructive of life. Argon, an inert gas, is the third most abundant gas in the atmosphere.

We hope you would find this helpful. The temperature here is nearly constant, and hence, it is called the Tropopause.

Contactus Work with us Advertise with us Contact Us. While the flow of energy is unidirectional with loss of energy at each tropic level through respiration, nutrients get circulated between living and non-living components indefinitely. Troposphere, Stratosphere, Mesosphere, Thermosphere Exosphere. Water-Vapour Water vapour is also a variable gas in the atmosphere, which decreases with altitude. Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.

This law also predicts that the composition of a gas mixture will change with altitude, cost center in tally erp 9 pdf the lower-molecular weight components being increasingly favored at higher altitudes. Composition of the Atmosphere.

Composition of the Atmosphere

The shaded D- and E-layers are regions of high ion concentrations that reflect radio waves and are important in long-distance communication. These relative amounts are controlled by the rates of the reactions that interconvert the various forms of carbonate. Biogeochemical Cycles or Nutrient Cycles Energy flow and nutrient circulation are the major functions of the ecosystem.

It is transparent to the incoming solar radiation but opaque to the outgoing terrestrial radiation. The chemical formulas at the right show the major species of interest in the various regions. Photosynthesis in plants usually comprises the chlorophyll and produces oxygen as a by-product.

Carbon cycle involves a continuous exchange of carbon between the atmosphere and organisms. The troposphere is the lowermost layer of the atmosphere. It contains electrically charged particles known as ions, and hence, it is known as ionosphere.

It forms the bottom-part of thermosphere. This nitrogen gets converted to multiple forms. If the amount of an infrared-absorbing gas such as carbon dioxide increases, a larger fraction of the incident solar radiation is trapped, and the mean temperature of the earth will increase.

Photosynthesis The green plants use sunlight to produce nutrients from carbon dioxide and water. This is the most important layer for all biological activity. Your email address will not be published. The volume of other gases is constant but the volume of carbon dioxide has been rising in the past few decades mainly because of the burning of fossil fuels. This gives rise to a pressure gradient that is the most predictable and well known structural characteristic of the atmosphere.

Stratosphere is that it contains the ozone layer and hence, this layer absorbs ultra-violet radiation and shields life on the earth from intense, harmful form of energy. Radio waves transmitted from the earth are reflected back to the earth by this layer. Water vapour also decreases from the equator towards the poles. The column of atmosphere is divided into five different layers depending upon the temperature condition. Structure of the atmosphere.

Plz provide all material in sequence manner. Apart from carbon, hydrogen and oxygen, nitrogen is the most prevalent element in living organisms.
