OZONE LAYER SHIELD OF THE EARTH




Psalms 47:9
The princes of the people are gathered together, [even] the people of the God of Abraham: for the shields of the earth [belong] unto God: he is greatly exalted.

Job 28:24
For he looketh to the ends of the earth, and seeth under the SHADE of whole heaven;

Acts 4:12
Neither is there salvation in any other: for there is none other name under the SHADE of heaven given among men, whereby we must be saved.

Under the SHADE OF HEAVEN" in tagalog "SILONG NG LANGIT " is refer to the protective shade of the earth that block the gamma rays of the sun. 

Isaiah 4:6
There will be a shelter to give shade from the heat by day,..."

Shade is the blocking of sunlight (in particular direct sunshine) by any object, and also the shadow created by that object. Shade also consists of the colors grey, black, white, etc. It may refer to blocking of sunlight by a roof, a tree, an umbrella, a window shade or blind, curtains, or other objects.

Shade is an important issue in temperate and tropical zones for providing cooling and shelter from the sun. it is earth canopy or earth tent againts solar radation of the sun.(Psalms 121:6,Mark 4:6)

"... He stretches out the sky like a canopy and spreads it out like a tent to live in.-Isaiah 40:22


"The Ozone Layer is like built-in sun screen for the whole Earth""The ozone layer is like an invisible layer of sunscreen for the entire planet, acting as a shield against ultraviolet radiation"It acts as a canopy, but it's a gaseous canopy, that is produced by UV radiation, and in turn absorbs the radiation that helped to produce it.

Earth Covering in skies

I dress the skies in darkness, covering them with clothes of mourning."(Isaiah 50:3)



The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun's high frequency ultraviolet light, which potentially damages the life forms on Earth.It is mainly located in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in detail by the British meteorologist G. M. B. Dobson, who developed a simple spectrophotometer (the Dobsonmeter) that could be used to measure stratospheric ozone from the ground. Between 1928 and 1958 Dobson established a worldwide network of ozone monitoring stations, which continue to operate to this day. The "Dobson unit", a convenient measure of the columnar density of ozone overhead, is named in his honor.

Distruction of Ozone layer:


"...and the heavens are the works of thine hands: They shall perish; but thou remainest; and they all shall wax old as doth a garment;(Hebrew 1:10-11)


Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% in the total volume of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events.

The details of polar ozone hole formation differ from that of mid-latitude thinning but the most important process in both is catalyticdestruction of ozone by atomic halogens.The main source of these halogen atoms in the stratosphere is photodissociation of man-made halocarbon refrigerants, solvents, propellants, and foam-blowing agents (CFCs, HCFCs, freons, halons). These compounds are transported into the stratosphere by winds after being emitted at the surface.Both types of ozone depletion were observed to increase as emissions of halocarbons increased.

CFCs and other contributory substances are referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (280–315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone generated worldwide concern, leading to adoption of the Montreal Protocol that bans the production of CFCs, halons, and other ozone-depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in sunburn, skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.
