Question 3 :

Give reasons.

i. Environmental aspects must be carefully looked into before building huge dams.

ii. Most industries are concentrated around coal mines.

iii. Petroleum is referred to as “black gold”.

iv. Quarrying can become a major environmental concern.

 

Answer :

i. Environmental aspects must be carefully looked into before building huge dams due to the following reasons:

  • Dams can create imbalance in the earth’s equilibrium if they are quite large.

  • Deforestation may lead to environmental pollution.

  • People have been displaced to build dams.

  • Settlements require shifting causing loss of jobs and livelihood for the people.

  • Flood threats are always there near the dams.

  • Earthquake threats also remain there around dams.

  • Silting of lakes affects the fertility of soil.

ii. Coal can be used as a source of energy and power and also as a raw material in most of the industries. Hence most industries are concentrated around coal mines to save the cost of transportation of coal from the mines to the industries.

iii. Petroleum is referred to as “black gold” because it is black in colour in the crude form and its derivatives are extremely valuable as petroleum itself. We use petroleum products in our day to day life such as nail paint, petrol, candle, latex, etc.

iv. Quarrying can become a major environmental concern due to the following reasons:

  • It can destroy the humus of soil which is needed for the growth of plants and crops.

  • It can produce a lot of noise pollution due to the use of explosives in order to break the huge chunks of rocks.

  • In the process of quarrying, a lot of dust is generated which causes air pollution and also certain occupational hazards.

  • Blasts done in the process of quarrying generate large vibrations which damage nearby buildings, dams or any other similar structure.
