O Level Geography of Pakistan chapter 3: Power MCQs with answers
By Team Megalecture · Updated 4 Nov 2026
36 exam-style questions on Power, each with the answer and a short explanation. Ten of them are below to try. The chapter test draws ten fresh questions each time and is marked the moment you finish, with your score by topic.
Try each one, then open the answer. These ten stay the same; the test draws new ones every time.
1. Why is a scheme such as Tarbela described as 'multi-purpose'?
A
it gives power, irrigation water and flood control
B
it burns several fuels to make electricity
C
it stores water drawn from several seas
D
it is shared by several countries at the same time
Show answer
Answer: A. The dam generates hydel power, stores water for canals in the dry season and helps to control floods downstream. Some reservoirs also support fishing and recreation.
2. Which of these is a renewable source of electricity?
A
natural gas
B
wind
C
uranium (nuclear)
D
coal
Show answer
Answer: B. Wind is renewed naturally and will not run out. Gas and coal are fossil fuels, and uranium for nuclear power is a mined mineral with limited reserves.
3. A textile mill in Faisalabad suffers long daily power cuts. Which is the most likely effect on the mill and the economy?
A
the mill can sell more cloth at lower prices
B
farmers grow more cotton to supply the mill
C
the mill's costs fall because it uses less power
D
output and exports fall, and jobs may be lost
Show answer
Answer: D. Machines stand idle during power cuts or run on costly generators, so output falls and costs rise. Orders may be lost to foreign competitors, reducing exports and jobs.
4. Why were pipelines built to carry oil products from Karachi to central Punjab instead of relying only on road tankers?
A
pipelines can also carry passengers and cargo
B
they move large volumes cheaply and ease road traffic
C
pipelines need no pumping stations anywhere along the route
D
road tankers are not allowed to carry oil products
Show answer
Answer: B. Once built, pipelines move oil continuously and cheaply, cutting the tanker traffic that damages roads and causes accidents. They still need pumping stations and are costly to build.
5. What is a disadvantage of generating electricity from the wind?
A
its fuel must be imported by sea
B
it produces radioactive waste
C
output varies because the wind speed changes
D
it gives off large amounts of carbon dioxide
Show answer
Answer: C. Turbines produce little power in calm weather, so wind farms need back-up from other sources. They burn no fuel and give off no carbon dioxide while working.
6. A coal seam appears at the surface on the side of a steep valley. Which mining method is most suitable?
A
drilling a well
B
open-cast mining
C
adit mining
D
shaft mining
Show answer
Answer: C. An adit is a level or gently sloping tunnel driven into the hillside along the seam, so coal can be brought out without lifting it up a shaft.
7. A power station in central Punjab burns coal imported through Port Qasim. How is the coal most likely to be carried from the port to the power station?
A
by pipeline, as a liquid
B
by air freight
C
by rail, in long trains of wagons
D
by barge along the Indus to Punjab
Show answer
Answer: C. Rail is the cheapest way to move heavy, bulky goods over long distances on land. Coal is not moved by pipeline, and the Indus is not used by barges.
8. What type of coal is found in the Thar coalfield of Sindh?
A
coking coal suitable for making steel
B
anthracite, the highest grade of coal
C
lignite, a low-grade coal
D
bituminous coal of export quality
Show answer
Answer: C. Thar coal is lignite: it contains a lot of moisture and gives less heat than higher-grade coals. The reserves are very large, but the coal is best burned close to the mine.
9. How does a reliable supply of electricity help farming in the Indus Plain?
A
it increases the amount of monsoon rain
B
it runs tubewells that pump water for irrigation
C
it makes the soil fertile without any need for fertiliser
D
it stops pests from attacking the crops
Show answer
Answer: B. Electric tubewells lift groundwater whenever crops need it, and power is also needed for cold stores and crop processing. Power cuts leave tubewells idle at key times.
10. Which source of electricity would suit a small, isolated village on the dry Balochistan Plateau, far from the grid, the coast and any river?
A
a micro-hydel scheme
B
a tidal power scheme
C
a nuclear power station
D
solar panels with batteries
Show answer
Answer: D. The plateau has strong sunshine on most days, and solar panels can be set up for a single village. Micro-hydel needs a flowing stream, tidal power needs the coast, and a nuclear station is far too large.
