Q77 (IAS/2025) Geography › World Physical Geography › Earth rotation and time Answer Verified

Consider the following statements : I. Anadyr in Siberia and Nome in Alaska are a few kilometers from each other, but when people are waking up and getting set for breakfast in these cities, it would be different days. II. When it is Monday in Anadyr, it is Tuesday in Nome. Which of the statements given above is/are correct?

Result
Your answer:  ·  Correct: A
Explanation

**Explanation:**

Statement I is correct. Anadyr, Russia is 21 hours ahead of Nome, Alaska.[2] This means that during morning hours when people are having breakfast in both cities, they are indeed on different calendar days. For example, when it is 1:24 AM Wednesday in Anadyr, it is 4:24 AM Tuesday in Nome.[4] However, it's important to note that while they are "a few kilometers" apart geographically (separated by the Bering Strait), they are separated by the International Date Line, which creates this time difference.

Statement II is incorrect. The statement reverses the time relationship. Since Anadyr is 21 hours ahead of Nome[2], when it is Monday in Anadyr, it would be Sunday (not Tuesday) in Nome. The 21-hour time difference means Anadyr is almost a full day ahead, so Nome is actually behind by one calendar day.

Therefore, only Statement I is correct, making option A the right answer.

This is a classic 'Concept applied to Map' trap. While the International Date Line (IDL) logic is standard static geography (GC Leong Ch 2), the specific city pairing (Anadyr vs Nome) acts as a distractor. The examiner tests if you can distinguish between the general proximity of landmasses (Bering Strait) and the precise logic of time travel across the 180° meridian.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
What is the distance in kilometers between Anadyr (Chukotka, Siberia, Russia) and Nome (Alaska, USA)?
Origin: Weak / unclear Fairness: Borderline / guessy
Indirect textbook clues
Environment and Ecology, Majid Hussain (Access publishing 3rd ed.) > Chapter 3: MAJOR BIOMES > 9. Taiga (Boreal) Biome or Coniferous Forest Biome > p. 15
Strength: 4/5
“Te taiga biome stretches from Alaska to the eastern coast Canada, Scandinavian countries and the entire extent of Eurasia from the Europian Russia to Siberia. It is confned mainly to the northern Hemisphere. Te high altitudes of Himalayas, Andes, Rockies, Alps, etc. are also covered with the trees of this biome. However, montane forests of needle-leaf trees exist worldwide at high elevation. Tis biome is characterised by extreme continentality. Te highest annual range of temperature in the northern Hemisphere is recorded in this biome. Verkhoya-nsk of Siberia records the lowest temperature of –69o C in the northern Hemisphere. Tere is permafrost of soil from 5 to 7 months.”
Why relevant

Says the taiga/tundra biome stretches from Alaska across Eurasia to Siberia, implying geographic continuity and relative proximity of far-eastern Siberia and western Alaska.

How to extend

A student could look at a map to locate Anadyr in Chukotka and Nome on the Seward Peninsula and infer they are relatively close across the Bering region, suggesting a cross-Bering distance rather than a transcontinental one.

Certificate Physical and Human Geography , GC Leong (Oxford University press 3rd ed.) > Chapter 25: The Arctic or Polar Climate > The Importance and Recent Development of the Arctic Region > p. 236
Strength: 3/5
“The Arctic region, once regarded as completely useless, is now of some economic importance. Apart from the efforts of the various governments in assisting the advancement of the Arctic inhabitants, the Eskimos, Lapps, Samoyeds, etc., new settlements have sprung up because of the discovery of minerals. Gold is mined in Alaska, nickel near Petsamo, U.S.S.R., petroleum in the Kenai Peninsula, Alaska; and copper at the Rankin Inlet, Canada. With the establishment of ports on the Arctic seaboard of Eurasia, it is now possible to ship timber and fur from Siberia. Though the ports, such as Igarka at the mouth of the Yenisey, are not ice-free, modern ice-breakers keep the passage open most of the time.”
Why relevant

Mentions shipping/ports on the Arctic seaboard of Eurasia and ability to ship timber and fur from Siberia, implying maritime connections between Arctic Siberia and North America.

How to extend

Using a world map, a student could note the short sea-crossing distances in the Bering/Arctic areas (e.g., between Siberian and Alaskan ports) to judge that Anadyr–Nome is likely on the order of hundreds — not thousands — of kilometers.

INDIA PHYSICAL ENVIRONMENT, Geography Class XI (NCERT 2025 ed.) > Chapter 1: India — Location > INDIA – LOCATION > p. 2
Strength: 5/5
“Let us try to analyse the implications of having such a vast longitudinal and latitudinal extent. If you work out the latitudinal and longitudinal extent of India, they are roughly about 30 degrees, whereas the actual distance measured from north to south extremity is 3,214 km, and that from east to west is only 2,933 km. What is the reason for this difference? Consult Chapter 3 on the topic Latitude, Longitude and Time in the book Practical Work in Geography – Part I (NCERT, 2006) to find out. This difference is based on the fact that the distance between two longitudes decreases towards the poles whereas the distance between two latitudes remains the same everywhere.”
Why relevant

Explains that distance between longitudes decreases toward the poles, a geographic rule relevant when estimating east–west distances at high latitudes like Anadyr/Nome.

How to extend

A student can combine the rule with the approximate longitudes of Anadyr and Nome (from a map) and compute the smaller km-per-degree longitude at their high latitudes to estimate the great-circle distance.

Environment, Shankar IAS Acedemy .(ed 10th) > Chapter 3: Terrestrial Ecosystems > 3.1. TUNDRA > p. 24
Strength: 4/5
“5I{ANKAR IAsACADEMY Tundra means a "barren land" since they are found where environmental conditions are very severe. There are two types of tundra- arctic and alpine. Distribution: Arctic tundra extends as a continuous belt below the polar ice cap and above the tree iine in the northern hemisphere. It occupies the northern fringe of Canada, Alaska, European Russia, Siberia and island group of Arctic Ocean. On the south poie, tundra is very small since most ofit is covered by ocean . Alpine tundra occurs at high mountains above the Arctic. With respect to Arctic, mountains are found at all latitudes.”
Why relevant

Describes Arctic tundra distribution occupying northern fringes of Alaska and Siberia, reinforcing that both locations lie in the high-latitude near-Arctic zone.

How to extend

Knowing both are high-latitude points, a student could use their latitudes on a globe and apply great-circle reasoning (shorter surface distances near the pole for given longitude differences) to estimate separation.
