THE ATMOSPHERE IS IN CONSTANT TRANSITION

THE OUT GASING OF THE ATMOSPHERE

Out gasing from the interior of the geosphere blends in with theprimordial, planetary disc gases,to form the first atmosphere.

As rock-metals are heated and pressurized from the compressingplanet, they change in composition,releasing gases.

The gases are expelled throughvolcanic ruptures and geologicrifts. The force of gravity onEarth is such that it can hold themost gases in a gaseous state, w/in thenormal range of earth temperatures.

OUT GASING

Page 5: The proto planetary disc, from which the earth is made, was composed of HHydrogen HeHelium NNitrogen OOxygen and other elements & simple molecules. THE

Each of the gases of the Atmosphereplays a role in converting the sun’sEnergy into usable energyA. Oxygen is highly combustible

and chemically reactive.B. Nitrogen is much less so. The

ratio of about 4:1 preventsOxygen from being too reactive

C. As Hydrogen reduced, free Oxygen and Ozone (O3) could form, screening out ultra violet light.

D. Carbon Dioxide (CO2) absorbsinfrared light holding heat

E. Water Vapor gasifies and condensesholding and moderating weather by fluxing between liquid & gaseousstates in the presence of heat

F. Clouds (water & particulates)provide solar reflectivity (Albedo)

Nitrogen 78%

Oxygen 21%

The atmosphere is comprised of6.0 quadrillion (6.0E+15) tons, or about 30 million tons / mi^2 of gasesthat surround the geosphere.A. The principle gases that make up

The atmosphere include Nitrogen c78% Oxygen c21% Argon c <1%

B. In addition there are other importantgases of lesser quantities including Carbon Dioxide (CO2) c 0.0003% Water Vapor (H2O) < 1%

C. The atmosphere acts as a fluid medium within which energy and chemicals can be transferredthat sustain life >> for example, Oxygenis taken from the atmosphere and combined with sugars for respiration,the key energy release process for living things—the by-product of Carbon Dioxide is used in Photosynthesis

ATMOSPHERES COMPOSTION

Page 7: The proto planetary disc, from which the earth is made, was composed of HHydrogen HeHelium NNitrogen OOxygen and other elements & simple molecules. THE

The Atmosphere acts as a shieldaround the earth allowing only a narrow range of energy to reachthe surface.A. Ultra Violet light and other

high energy waves are reduced byreflection and dissipation

B. This stabilizes energy input fromthe sun so that the chemical processesof life can operate

C. It also screens the earth from space debris which would also disrupt the biosphere

D. In addition, the atmosphere acts tomoderate the fluctuating light wavesof the sun into a stable temperature.

E. The consequences of the dissipation, absorptionand reflection of the sun’s rays is that gasesin the Atmosphere undergo chemical changes,resulting in Atmospheric Chemical Cycles(including Ozone, Greenhouse, and Acid…

Oxygen prefers partnering as a diatomic (2) oxygen molecule.

As O2 is struck with UVc light from the Sun, the O2 breaks apart into free Oxygen.

The fee Oxygen combines with O2 and forms an unstable O3.

When Ozone (O3) is struck with UVb, it breaks the O3 into an O2 molecule and free Oxygen atom.

A. Atmospheric Heat can be Expressed as an Equation which reads

Solar Energy + 78% N2 + 21% O2 + 1% Other Gases= Atmosphere Content + Temperature

B. The presence of “Other Gases” controls the absorption rate of heat from the sun

C. The light coming in is absorbed by the earthand radiated as heat.

D. The radiated heat is absorbed by “OtherGases (Greenhouse Gases)” and retained.

E. This process is called the Greenhouse Effect

The energy from the sun over timeestablishes a pattern of weather referredto as climate. There are several factorsthat govern climate including

A. The more curved the earth based onlatitude, the more light is deflected,the less heat is available

B. The tilt of the earth on its axis movesthe intensity of light at any locationover the year causing seasons

C. Surface color and texture vary inhow much heat is retained

D. Ocean currents move warm & coldwater to varying locations

E. Topography influences wind andwater condensation patterns

Page 11: The proto planetary disc, from which the earth is made, was composed of HHydrogen HeHelium NNitrogen OOxygen and other elements & simple molecules. THE

1. Light from the sunheats air causing itto expand

2. When light is less,the air cools & condenses resultingin large air massesof cooler hi pressure, dense air, and warm low pressure air.

3. When warmer low pressure air meetswith cool, hi pressureair, the differential pressures generatelocalized winds

5. The more dramatic the pressure/temp differentials,the greater the airinstability, and the more the weathervolatility.

When UVb strikes the CFC Oxide, it does nothing. The UVb simply passes on to the earth’s surface.

Sunlight reaching the atmosphere is either reflected or absorbed.Reflected light returns to space. Absorbed light is converted to heat. Heat radiating from the Earth is absorbed by the Greenhouse Gases in the Greenhouse effect. The greater the Greenhouse Gas concentration,The more heat that is absorbed and retained.

1. Acid Rain will fall on the earth’s surface changing the acid ph of all ocean and fresh water below it.

2. Rocks exposed to Acid Rain will erode and dissolve faster.

3. Acid rain in soil increases soil acidity which impacts plant species.

4. A perpetual change in the Ph of water alters the DNA of affected species.

5. Altered DNA increases mutation rates, stressing reproductive balance.
