“Greenhouse Effect” refers to the process by which absorption and emission of infrared radiation atmosphere gases (mainly Greenhouse gases such as CO‚ NO‚ and Carbon Monoxide) warms the Earth’s atmosphere and surface. b) Solar Variations- Solar variations are changes in the amount of radiant energy emitted by the Sun. It is believed that the more radiant energy emitted by the Sun‚ the hotter the Earth’s atmosphere will become since more heat energy will be produced. 3. EFFECTS OF GLOBAL WARMING:

INTRODUCTION Air pollution is the introduction into the atmosphere of chemicals‚ particulates‚ or biological materials that cause discomfort‚ disease‚ death to humans‚ damage other living organisms such as food crops‚ or damage the natural environment. The composition of air are nitrogen‚ oxygen‚ inert gases and others and carbon dioxide. There are few major air pollutants such as carbon monoxide‚ sulphur oxides‚ hydrocarbons and photochemical oxidants. The major effects of air pollutions are greenhouse

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 of our pollution. As discussed in the film‚ the atmosphere is divided into several layers by density and

major eras: the Precambrian‚ the Paleozoic‚ the Mesozoic and the Cenozoic. The Precambrian era covers most of our planet’s history and lasted from Earth’s inception until 542 million years ago. It was during this era that the Earth became solid‚ the atmosphere became breathable and life emerged. There is little evidence about the events that led to the creation of our planet billions of years ago. Most of the knowledge we have about Earth’s beginnings comes indirectly from meteorites that smashed into

Temperatures range from high to low on Jupiter because of all the types of gases and layers that they are in‚ such as the upper atmosphere where it is colder and increases closer to the center. At the top of Jupiter’s clouds the temperature is around -230 degrees Fahrenheit or -145 degrees Celsius. Jupiter’s temperature increases as you descend closer to the center of the planet. The

In “To Paint a Water Lily‚” by Ted Hughes‚ the speaker examines the complex aspects of nature by revealing the challenges he faces as an artist in capturing its real meaning. When he looks at the scene‚ he sees an exciting little world of constant movement and activity‚ hidden by the peaceful stillness of the water lilies that float at the surface of the pond. Ted knows that to paint the water lily and do it righteousness requires more than a simple description of the plant itself—he must also somehow

The atmosphere that is created is a one of suspense‚ gusto and fervour. Everyone is speaking with a real passion and their keenness is overwhelming with enthusiasm. At first it all great and cheerful but then the cameraman doubts the scenario and thinks it wouldn’t pull through and this is where the suspense comes from and then it happens and there

According to a United Nations Environment Programme (1997) brochure‚ large volcanic eruption put tiny particles in the atmosphere that block the sunlight‚ resulting in surface cooling down of few year’s duration. Besides‚ ocean current level is the one cause of climate change‚ the changing of variation in ocean currents distribute the heat and unstable rain. As the naturally

It’s said that by the time a baby born today is 80 years old‚ the world will be 6 and a half degrees warmer than it is now. Is global warming bad? The earth is naturally warmed by rays (or radiation) from the sun which pass through the earth’s atmosphere and are reflected back out to space again. The atmosphere’s made up of layers of gases‚ some of which are called ’greenhouse
