Ozone layer !!
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 is potentially damaging to life on earth.[1] Over 90% of ozone in earth's atmosphere is present here.[1] "Relatively high" means a few parts per million—much higher than the concentrations in the lower atmosphere but still small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from approximately 15 km to 35 km above Earth's surface, though the thickness varies seasonally and geographically.[2] 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 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 continues to operate today. The "Dobson unit", a convenient measure of the total amount of ozone in a column overhead, is named in his honor.
Ten percent of the ozone in the atmosphere is contained in the troposphere, the lowest part of our atmosphere where all of our weather takes place. Tropospheric ozone has two sources: about 10 % is transported down from the stratosphere while the remainder is created in smaller amounts through different mechanisms.
Ozone depletion
The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), hydroxyl (OH), atomic chlorine (Cl), and atomic bromine (Br). While there are natural sources for all of these species, the concentrations of chlorine and bromine have increased markedly in recent years due to the release of large quantities of manmade organohalogen compounds, especially chlorofluorocarbons (CFCs) and bromofluorocarbons.[citation needed] These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 100,000 ozone molecules. Ozone levels, over the northern hemisphere, have been dropping by 4% per decade. Over approximately 5% of the Earth's surface, around the north and south poles, much larger (but seasonal) declines have been seen; these are the ozone holes.

what is the Global warming !!
Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century and its projected continuation.
CAUSES : The Earth's climate changes in response to external forcing, including variations in its orbit around the Sun (orbital forcing),changes in solar luminosity, volcanic eruptions, and atmospheric greenhouse gas concentrations. The detailed causes of the recent warming remain an active field of research, but the scientific consensus is that the increase in atmospheric greenhouse gases due to human activity caused most of the warming observed since the start of the industrial era. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. Some other hypotheses departing from the consensus view have been suggested to explain most of the temperature increase. One such hypothesis proposes that warming may be the result of variations in solar activity.
EFFECTS:
The predicted effects of global warming on the environment and for human life are numerous and varied. It is generally difficult to attribute specific natural phenomena to long-term causes, but some effects of recent climate change may already be occurring. Raising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences, but predictions for secondary and regional effects include extreme weather events, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact. Concerns have led to political activism advocating proposals to mitigate, eliminate, or adapt to it

a s s i g n m e n t 2 !! c a l e n d a r !!
my final design calendar
my statment:
EID AL-FITR IS DAYS OF FORGIVNESS
description :
EID AL-FITR (Hari Raya )
WHEN ?
Eid al-Fitr falls on the first day of Shawwal, the month which follows Ramadan in the Islamic calendar.
WHY IS EID AL-FITR IS DAYS OF FORGIVNESS ?
It is a time to give in charity to those in need, and celebrate with family and friends the completion of a month of blessings and joy, its to forgive your friends and all thee people that you fight with them and to start a new pages !! with out any heart feeling .
i pot the DARK BLUE as abackground toshow the nights of these days .. everyone is calabreating in the nights with friends everyone is happy coz ALLAH forgive there sins
after all there prayer and fasting in ramadan, they also all the muslims family gives a determined amount as a donation to the poor. This donation is of actual food -- rice, barley, dates, rice, etc. -- to ensure that the needy can have a holiday meal and participate in the celebration. This donation is known as sadaqah al-fitr , to let the poor people share celebration with them
THIS CALENDAR FOR WHO?
to family-friends

THIS CALENDAR FOR WHO?
to family-friends
this is the design in the right bottom of my calendar
1- pen tool:
a- the mousqe
the effect i hve used to make the mousqe is
3D which is
effect>>3D>> revolve
2- type tool:
use it for type the words and numbers
3- rounded rectangle tool:
use it to drow boxes of days
4- star tool:
to drow stars.
5-brush tool:
to drow the line which are in right bottom of calendar
6-ellipse tool :
todrow the moon and edit it by pen tool
i used
( make clipping mask )
to make it as a moon
7- rectangle tool:
i use it to drow the box behind number
and for the gray box i use crystallizy to make that
design around it .
i add effect to stars and october-2008 word
which is
effect>> blur>> gaussian blur
