Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now‚ this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet‚ even though it is also part

and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth‚ the thinner the atmosphere gets. 1.TROPOSPHERE This is the layer of the atmosphere closest to the Earth’s surface‚ extending up to about 10-15 km above the Earth’s

year‚ the International Day for the Preservation of the Ozone Layer is celebrated. This date has been designated by the United Nations General Assembly in its resolution 49/114‚ to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. | This commemoration around the world offers an opportunity to focus attention and action at the global‚ regional and national levels on the protection of the ozone layer.

In this research‚ the interrelationships between the above are elaborated as well. Background The depletion of forests‚ which is generally known as deforestation is discussed with the intention of finding solutions to it. The rate at which it is taking place is alarming and today it has become a global crisis. There are a number of reasons and ways that

An aquifer is an underground layer of water bearing rock. Many areas on earth have an underlying aquifer‚ which can supply fresh water through the use of a well. Aquifers were first tapped for water in the early 1900 ’s for irrigation. Aquifers were originally believed to be an inexhaustible resource thus humans began tapping them for municipal and industrial uses as well (Aquifer‚ 2007). Now‚ many countries are over pumping aquifers in a struggle to fulfill their growing water supply demands. For

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans. The

Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes)‚ • chemical composition‚ • movement‚ and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20

Introduction Ego depletion is the idea that self-control draws upon limited resources that are used up. This idea has been formed on the basis that when energy for mental activity is low‚ self-control is typically weakened which is considered a state of ego depletion (David McRaney 2012). This idea places a focus on willpower as a limited resource that is easily drained‚ especially when we engage in acts of self-control. For example‚ if someone was deprived of their food during the day and were
