UPPSC 2025 Prelims GS Paper-I · Question 72 of 150

Correct — A, A-4, B-1, C-2, D-3. The Appalachian coalfield (A) is the great coal basin of the eastern United States (4), running down the Appalachian belt through Pennsylvania, West Virginia and Kentucky; it is one of the three largest coal-producing regions of the USA alongside the Powder River Basin and the Illinois Basin. Lancashire (B) is a coalfield of North West England (1), spread over roughly 550 square miles of Lancashire, Greater Manchester, Merseyside and part of Cheshire, and it was one of the cradles of the Industrial Revolution. The Ruhr (C) lies in Germany (2), in the state of North Rhine-Westphalia, taking its name from the river Ruhr; with almost 300 collieries working by 1850 its coal fed the coke ovens and blast furnaces that made this Europe's largest industrial region by 1870. The Kuzbass or Kuznetsk Basin (D) is in Russia (3), in Kemerovo Oblast in south-western Siberia — about 26,000 square kilometres of coal measures that today yield roughly 60 per cent of Russia's coal.

• (b)A-1, B-4, C-2, D-3 — It gets the Ruhr and the Kuzbass right but swaps the first two, sending the Appalachian coalfield to England and Lancashire to the United States. The Appalachians are the mountain system of eastern North America, and Lancashire is an English county — the two cannot cross.
• (c)A-1, B-4, C-3, D-2 — Every pair here is wrong. It carries the same Appalachian-Lancashire swap as option (b) and adds a second one, putting the Ruhr in Russia and the Kuzbass in Germany. The Ruhr is named after a German river and the Kuznetsk Basin after the Siberian town of Kuznetsk, so the two are not interchangeable.
• (d)A-4, B-1, C-3, D-2 — The most tempting wrong answer, because it places the Appalachian coalfield in the USA and Lancashire in England correctly and only fails on the last two — assigning the Ruhr to Russia and the Kuzbass to Germany. The Ruhr is in North Rhine-Westphalia, Germany; the Kuznetsk Basin is in Kemerovo Oblast, Russia.

The world's classic coalfields are named after the river valley, basin or county in which the coal measures outcrop, and each anchored a heavy-industrial region built on the coal-plus-iron combination: coal to coke, coke to pig iron, pig iron to steel. The Appalachian belt underpinned the American manufacturing belt around Pittsburgh; Lancashire and the adjoining Yorkshire and Midlands fields powered Britain's Industrial Revolution; the Ruhr made Germany an industrial power and later became the core of the European Coal and Steel Community; and the Kuznetsk Basin was developed in the 1930s as the eastern half of Stalin's Ural-Kuznetsk industrial combine.

Match-list questions on world coalfields are answered by hooking each name to a language and a landscape rather than by rote. 'Appalachian' is a North American mountain name; 'Lancashire' is unmistakably an English county name; 'Ruhr' is a German river; and 'Kuzbass' is a Russian contraction of Kuznetsky Bassein (Kuznetsk Basin). Once you spot that every option offers only two possible partners for each entry, the question collapses into two independent yes-or-no decisions — Appalachian versus Lancashire, and Ruhr versus Kuzbass — and getting either pair right eliminates half the options.

• Appalachian Basin, eastern USA — West Virginia and Kentucky are its leading producers; one of America's three biggest coal regions with the Powder River Basin (Wyoming, Montana) and the Illinois Basin
• Lancashire Coalfield, North West England — about 550 square miles across Lancashire, Greater Manchester, Merseyside and part of Cheshire; it drove Britain's first canals and steam engines
• Ruhr, Germany — in North Rhine-Westphalia, named after the river Ruhr; almost 300 mines were working by 1850 and it was Europe's largest industrial area by 1870
• Kuznetsk Basin (Kuzbass), Russia — Kemerovo Oblast, south-western Siberia, about 26,000 sq km; produces roughly 60 per cent of Russia's coal and was second only to the Donbas in Soviet times
• The Donets Basin (Donbas), centred on Donetsk in Ukraine, was the Soviet Union's largest coalfield — a name frequently offered as a distractor alongside the Kuzbass

• Swapping the Ruhr and the Kuzbass — the commonest error in this item, since both are short unfamiliar names and options (c) and (d) both exploit it
• Confusing the Kuzbass (Kuznetsk Basin, Russia) with the Donbas (Donets Basin, Ukraine); the Donbas was the larger Soviet field, the Kuzbass the second
• Reading 'Lancashire' as a place outside Britain because the surrounding names are continental

UPPSC asks world coalfields as a straight match-list of field to country, and Indian coalfields as a match-list of field to river valley; UPSC prefers a single-choice locator — in which State is a named coalfield situated.

• practice — not a real PYQ

  The Donbas (Donets Basin) coalfield lies mainly in which country?

  • (a)Poland
  • (b)Ukraine
  • (c)Romania
  • (d)Belarus

  Answer(b) Ukraine — centred on Donetsk, it was the largest coalfield of the former Soviet Union, with the Kuznetsk Basin in Russia second.

• practice — not a real PYQ

  Which one of the following pairs of coalfield and country is NOT correctly matched?

  • (a)Silesia — Poland
  • (b)Ruhr — Germany
  • (c)Yorkshire — England
  • (d)Kuzbass — Ukraine

  Answer(d) Kuzbass — Ukraine. The Kuznetsk Basin is in Kemerovo Oblast, Russia; Ukraine's coal heartland is the Donbas.
