sunlight through but traps the warm air from escaping. The warmed structures and plants inside the greenhouse re-radiate some of their thermal energy as glass is partly opaque causing convection due to energy trapped inside the glasshouse. The blanket layer of gases in particular carbon dioxide traps much heat and prevents it from escaping back into space as radiation. Mother Earth is gradually warmer as air is trapped as created by the ‘greenhouse effect’. The air that is warmed near the ground is prevented

AIR POLLUTION What is Air Pollution? Pollution is now a common place term‚ that our ears are attuned to. We hear about the various forms of pollution and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air‚ irrespective of indoors or outside. A physical‚ biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases‚ dust‚ smoke enters into the atmosphere and makes it difficult

Neutrino What is neutrino ? A neutrino is an electrically neutral‚ weakly interacting elementary subatomic particle with a half-integer spin‚ chirality and a disputed but small non-zero mass. It is able to pass through ordinary matter almost unaffected. The neutrino (meaning "small neutral one") is denoted by the Greek letter ν (nu). Neutrinos are similar to the more familiar electron‚ with one crucial difference: neutrinos do not carry electric charge‚ which means that they are not affected by

CFC (cloro fluro carbon) is a stable compounds used in aerosol propellants in sprayers refrigeration’s & for depletion of ozone layer to the extent of 3%-4%. In the last 100 years the ozone in the higher atmosphere serves as shield protecting the earth from harmful ultraviolet radiation enters the earth surface & may

Definition Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. II. Why it is dangerous? Pollution disturbs our ecosystem and the balance in the environment. With modernization and development in our lives pollution has reached its peak; giving rise to global warming and human illness. III. Types & Causes of Pollution A. Air pollution It occurs when

smothers the animal and eventually kills it. Climatic change: Coral can loose its colour or even die from a change in its climate such as a cyclone or global warming. All the pollution that humans send up into the atmosphere thins the Ozone Layer. The Ozone Layer is meant to filter out the harmful UV rays‚ but because there is now a hole in it‚ some rays get through and heat the water temperature (Global Warming). The coral cannot survive the warmer sea temperatures. Other threats: -Crown of thorns

This may increase cataracts and weaken the immune system and cause skin cancer. It may also disrupt the eco system.

Can you give me an example? Dr.H : Well ozone is one example. Ozone is a poisonous gas that can cause breathing problems. It’s very bad for asthma patients. Hisyam : These unwanted chemicals in the air. I suppose you could call them pollutants. Dr.H : Yes‚ pollutants‚ because they pollute the air. Hisyam :
