12. SOURCE BASED QUESTIONS:
The term greenhouse is derived from the analogy to a greenhouse used in cold areas for preserving heat. A greenhouse is made up of glass . The glass which is transparent to incoming short wave solar radiation is opaque to outgoing longwave radiation. The glass, therefore, allows in more radiation and prevents the long wave radiation going outside the glass house, causing the temperature inside the glasshouse structure warmer than outside. When you enter a car or a bus, during summers, where windows are closed, you feel more heat than outside. Likewise during winter the vehicles with closed doors and windows remain warmer than the temperature outside. This is another example of greenhouse effect.
I) For which area is greenhouse effective?
a) Coldb) Hotc) Bothd) None
II) Incoming solar radiation come in form of:
a) Short wavesb) Long wavesc) Bothd) None
III) Why do we feel more heat than outside, When we enter into a car or a bus, during summers, where windows are closed?
a) Due to greenhouse effectb) Due to cold house effectc) Due to bamboo house effectd) All
IV) The glass in greenhouse is opaque for:
a) Long wave radiationb) Short wave radiationc) Bothd) None
13. What do you understand by the term “Greenhouse Gases”? Make a list of greenhouse gases.
ANS.- Greenhouse gases are those gases which cause global warming and result in rising in atmospheric temperature. These gases absorb long wave radiation. The processes that warm the atmosphere are often collectively referred to as the greenhouse effect.
Greenhouse Gases are-Carbon dioxide, Chlorofluorocarbons, Methane, Nitrous oxide, Ozone, Nitric oxide, Carbon monoxide etc.
14. What is global warming? What are its effects.
ANS. –The increasing trend in concentration of greenhouse gases in atmosphere may, in the long run, warm up earth. It is called global warming.
Followings are its effects:
i) Rise in the sea levelii) Loss of coastal landiii) A change in precipitation patterniv) Increased risks of droughts and floodsv) Threats to biodiversity.
