Answers
Answer:
1. Rise in temperature
Melting of glaciers will increase.
2. Solar Energy and Wind Energy
Answer:
Ans 1 ) Wheezing and coughing
Ans 2) Whisky and Elephant grass
Ans 3 ) Two initiatives that can be taken to reduce damage of Taj Mahal are -
a. The presence of pollutant SO2 has caused damage to Taj Mahal .
b. The presence of Acid Rain damage the marbles of Taj Mahal .
Ans 4 ) Any two advantages of zoning are -
a. Zoning can insure the availability of an adequate number of parking spaces .
b. Zoning can conserve environmentally sensitive areas .
Ans 5 ) Any two advantages of using geothermal energy.
a. Geothermal energy is more environmentally friendly than conventional fuel sources such as coal and other fossil fuels.
b. Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power.
Ans 6) We need Alternative fuels because -
. Alternative fuels are derived from sources other than petroleum. Most are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel.
Ans 7 ) The burning of biomass fuels results in exposure to
high levels of indoor air pollution, with consequent health effects. Possible interventions to reduce the exposure include changing cooking practices and introduction of smoke-free stoves supported by health education. Eighty percent of rural women cooked indoors using biomass fuel with no ventilation. Rural women reported two to three times more respiratory disease in their children and in themselves compared to the other two groups
Ans 8 ) Meteorological data helps:
a. identify the source of pollutants
b. predict air pollution events such as inversions and high-pollutant concentration days
c. simulate and predict air quality using computer models.
Ans 9) Two Advantages of using solar energy are -
a. Diverse Application
b. Reduces Electricity bills
One Disadvantage of using solar energy are -
. Weather Dependent
Ans 10) Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth's surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.
Advantages of Geothermal Energy are -
a. Since geothermal energy is a naturally occurring resource there is no fuel required, such as with fossil fuels that are a finite resource which needs mining or otherwise extracting from the earth.
b. Energy generated from this resource is easy to calculate since it does not fluctuate in the same way as other energy sources, such as solar and wind. This means we can predict the power output from a geothermal plant with a high degree of accuracy.
