Effect of CCl3F on Canada’s Ozone Layer Data Analysis and Interpretation 1. It took 25 yrs for CCl3F to enter the stratosphere (1930 to 1955). 2. The ozone layer above Canada began to decline in 1975. 3. Once the production of CCl3F was drastically reduced‚ it took 20 years for the CCl3F levels to decrease in the stratosphere. Conclude and Communicate 4. CFCs (Chlorofluorocarbons) are inorganic man-made chemicals that have been in production for more than 50 years in Canada. They were

stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while stratospheric Or‚ is decreasing. This decrease is called Ozone Depletion Ozone depletion deals

<b>The Greenhouse Effect</b> <br>The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases primarily carbon dioxide‚ methane‚ and nitrous oxide. <br> <br>Energy from the sun drives the earth’s weather and climate‚ and heats the earth’s surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour‚ carbon dioxide‚ and other gases) trap some

ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

GROUND WATER THE WATER/HYDROLOGIC CYCLE * Composed of evaporation from the oceans * Movements of moist air inland * Condensation and precipitation * Run-off on the surface or sub-surface back to the ocean * Plus additional minor cycles * Involves the exchange of water with the atmosphere‚ the earth‚ and the different water forms * Done when clouds gain water vapor from the various water forms * Evaporation – process where water turns into steam or gas when the

Ground water! What is it? Well it’s basically self-explanatory and is any water that is held under ground. That is only a very simple definition of it though and well in fact ground water is very critical to every ones life locally and worldwide. Most of the water that you drink comes from ground water and not from lakes and rivers even though those are considered as a part of ground water components. Ground water has many components that it can be divided into and this paper will explain what

Subliminal Priming on Ambiguous Figure Perception Misa Tsuruta‚ M.A.1 Abstract ~ Figure-ground organization is a kind of perceptual organization that has been studied in Gestalt psychology. Ambiguous/reversible figures can evoke two different percepts. When we see ambiguous figures‚ sooner or later our perceptual system determines one side that stands out as the figure‚ while the other side forms the ground and becomes shapeless. Subjects were subliminally trained with the half-figures of the target

Ground rules work as a codes of behaviour and help in maintaining good relationship between teacher‚ the class and among learners themselves. I would agree ground rules in small groups and then obtain a whole class consensus. Good

Article Reflection: Ozone Layer Ozone: The Pollution Paradox This article was based on information about ozone pollution. In my opinion this article gave a lot of valuable information and I learned a lot of things I never had knowledge of. For example‚ the atmosphere forms and destroys the ozone‚ the ozone can have an effect on the human body and the article also provided information on what we could do about the ozone layer to help the atmosphere. I had a little bit of information in my

But there is a significant pending problem in the ozone layer. Each year‚ a large hole appears in it. It is not an actual hole‚ like a hole in a pocket‚ but a thinning in the layer that shows up on satellite pictures. The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal‚ according to measurements researchers made there only
