Q1GeographyWorld Physical GeographyPYQ 2026

Ships from which of the following countries have to cross the Strait of Hormuz to reach out to the Indian Ocean? 1. Bahrain 2. Syria 3. Qatar 4. Egypt Select the answer using the code given below:

  • A1 and 2
  • B1 and 3Correct
  • C2 and 3
  • D3 and 4

Explanation

UPSC provisional key: (B), Series A question 30. Bahrain and Qatar have their coasts inside the Persian Gulf. To sail from those coasts to the open Indian Ocean, ships pass through Hormuz into the Gulf of Oman and Arabian Sea. This is a question about the coastal route, not the nationality printed on a ship registered elsewhere.

Sources: UPSC provisional answer key · U.S. EIA — Hormuz location and Persian Gulf route · U.S. EIA — world maritime chokepoints and Suez

Why the other options are incorrect
Option A

Bahrain is inside the Persian Gulf, but Syria is on the Mediterranean. Syria’s normal sea route toward the Indian Ocean goes through Suez and the Red Sea, not out of the Persian Gulf through Hormuz.

Option C

Qatar fits the Gulf-to-Hormuz route, but Syria does not. Locating a country in West Asia is insufficient; the decisive point is which sea its ports face.

Option D

Qatar must use the Gulf exit, but Egypt has Mediterranean and Red Sea coasts. Access from Egypt to the Indian Ocean uses the Red Sea and Bab-el-Mandeb route rather than Hormuz.

Q2GeographyWorld Physical GeographyPYQ 2026

Which of the following statements with reference to Lake Turkana is/are correct? 1. It is the largest desert lake in the world. 2. The lake is situated in South Sudan along the eastern fringe of the Sahara desert. 3. The lake is listed as a UNESCO World Heritage Site and is also referred to as the ‘Jade Sea’. Select the answer using the code given below:

  • A1 only
  • B1 and 3 onlyCorrect
  • C2 and 3 only
  • D1, 2 and 3

Explanation

UPSC provisional key: (B), Series A question 39. Statements 1 and 3 are correct in the question’s usage. Turkana is a desert lake in the East African Rift, principally in Kenya with its northern end in Ethiopia, and is known as the Jade Sea. Strictly, the UNESCO inscription is “Lake Turkana National Parks,” rather than an unrestricted designation of the entire lake; statement 2’s South Sudan/Sahara location is wrong.

Sources: UPSC provisional answer key · UNESCO: Lake Turkana National Parks

Why the other options are incorrect
Option A

Statement 1 is correct: UNESCO identifies Turkana as the world’s largest desert lake. But statement 3 is also accepted: the Lake Turkana National Parks form a World Heritage property and the lake is popularly called the Jade Sea.

Option C

Statement 2 is geographically incorrect: Turkana lies in the Kenya–Ethiopia region of East Africa, not in South Sudan on the Sahara’s eastern fringe. Statement 3 is accepted, but statement 1 should replace statement 2.

Option D

The inclusion of statement 2 makes this combination wrong. A desert lake is not necessarily in the Sahara: Turkana belongs to the East African Rift setting, while its largest-desert-lake status and Jade Sea association are correct.

Q3GeographyWorld Physical GeographyPYQ 2025

Consider the following countries: 1. Bolivia 2. Brazil 3. Colombia 4. Ecuador 5. Paraguay 6. Venezuela Andes mountains pass through how many of the above countries?

Option B

Four, not three, of the listed countries are traversed by the Andes: Bolivia, Colombia, Ecuador and Venezuela.

Option D

Only four of the six listed countries are Andean. Brazil and Paraguay are both outside the Andes system.

Q4GeographyWorld Physical GeographyPYQ 2024

Consider the following information: Region — Name of the mountain range — Type of mountain 1. Central Asia — Vosges — Fold mountain 2. Europe — Alps — Block mountain 3. North America — Appalachians — Fold mountain 4. South America — Andes — Fold mountain In how many of the above rows is the given information correctly matched?

  • AOnly one
  • BOnly twoCorrect
  • COnly three
  • DAll four

Explanation

Correct. Rows 3 and 4 are correct: the Appalachians and Andes are both fold mountains. Vosges is in Europe (not Central Asia) and is a block mountain, while the Alps are fold mountains (not block mountains).

Why the other options are incorrect
Option A

Two rows are correctly matched, not just one. Both the Appalachians and Andes are correctly identified as fold mountains in their respective regions.

Option C

Only two rows are correct. The Vosges are in Europe and are block mountains, and the Alps are fold mountains rather than block mountains.

Option D

Rows 1 and 2 contain errors. The Vosges are located in Europe and are block mountains; the Alps are fold mountains formed by tectonic compression.
