Question Passage:
erosion is regarded not merely as the physical removal of soil by water and wind, but rather as the ass deterioration of all the component parts of the habitat in Which man and his crops and livestock have to exist. Since there is no conclusive evidence for any major climatic in change in historic times to explain this deterioration, we  must conclude that the eroding of the total environment has been due primarily to thoughtless destruction of the vegetative cover. This has led to deterioration of the micro climate above and below the surface, generally in the | direction of a general drying out of the soil which has exposed it to erosive action of wind and rainfall of high intensity or frequency, and to the loss of organic matter in the soil, thus reducing its capacity to resist erosion by conserving the water that falls on the surface, If everything Possible is done within the total environment to _conserve the naturally planted or cultivated vegetation, this will also sure optimal conservation of soil and water. 

Answer the following question:

Which one is not the driver of soil erosion?

  Water

  wind

  surface water

  rainfall

Answer the following question:

The impoverishment of the world’s habitat is due to-

  man’s irresponsible abuse of the vegetation cover

  gradual deterioration of microclimate.

  drying out the soil

  removal of soil by water and wind

Question Passage:
Air pollution is caused mainly by emissions from road vehicles, factories, power Stations, aircraft and the like and by the ‘large-scale burning of vegetation. It has long been recognized as an environmental problem, and as a source of costs to both industry and entire communities. Only relatively recently, however, has the full Significance of the impact of such pollution become apparent. and the global dominant, potentially disastrous, environmental problem facing humanity. Since the mid-eighteen century the burning of fossil fuels, deforestation, and other changes in land use have resulted in substantial increases in the concentration of carbon dioxide, ‘Methane, and nitrogen oxides in the atmosphere. By blocking the radiation back into space of much of the heat reaching the earth from the sun, these gases reduce Significantly the natural cooling - ‘effect of such radiation, thus creating a ‘greenhouse effect’ and causing a steady increase in temperatures on earth global warming. Although the Claim that: the earth’s atmosphere IS heating up has been dispute by some climatologists, the balance of scientific opinion is now firmly behind the hypothesis.

Answer the following question:

The principle focus of the passage Is wren

  ciimatechange

  environment degradation

  emission of gasses

  nature of global warming
