Q1. [1] medium thorough-understanding
Which of the following correctly explains why thermal power stations are located close to coalfields rather than near cities they supply?
  1. A Coal is a bulky material that loses weight on use as it burns to ash, making long-distance transport costly and inefficient.
  2. B Coal releases toxic gases that make it unsafe to transport through populated areas.
  3. C Electricity cannot travel long distances through transmission lines without losing all its power.
  4. D Water needed for cooling turbines is only available near coalfields.

Model Answer

Answer: A

Coal is a bulky material that loses weight on use as it burns to ash, making long-distance transport costly and inefficient; hence thermal power stations are located near coalfields.

Source: Conventional Sources of Energy, Chapter 5

Explanation

The textbook explicitly states: "Coal is a bulky material, which loses weight on use as it is reduced to ash. Hence, heavy industries and thermal power stations are located on or near the coalfields." Option B is wrong as transport safety isn't the reason given. Option C is incorrect — electricity can travel long distances via transmission lines (that's why it's generated centrally). Option D has no textbook support.
