Q1Geography·Maps, Lat-Long, Time and Geographical TechniquesPYQ 2025
Consider the following statements:
1. Anadyr in Siberia and Nome in Alaska are a few kilometres from each other, but when people are waking up and getting set for breakfast in these cities, it would be different days.
2. When it is Monday in Anadyr, it is Tuesday in Nome.
Which of the statements given above is/are correct?
- A1 onlyCorrect
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Correct. Anadyr and Nome lie on opposite sides of the International Date Line, so their local dates differ despite geographic proximity. However, Anadyr is ahead of Nome, so when it is Monday in Anadyr it would still be Sunday in Nome, not Tuesday. Only Statement 1 is correct.
Q2Geography·Maps, Lat-Long, Time and Geographical TechniquesPYQ 2025
Consider the following countries:
1. United Kingdom
2. Denmark
3. New Zealand
4. Australia
5. Brazil
How many of the above countries have more than four time zones?
- AAll the five
- BOnly four
- COnly threeCorrect
- DOnly two
Explanation
Correct. The United Kingdom (including overseas territories such as Gibraltar, Bermuda and Pitcairn), Australia (mainland zones plus territories like Lord Howe, Norfolk and Christmas Island) and Brazil (Acre through Fernando de Noronha) each span more than four time zones. Denmark and New Zealand do not exceed that threshold.
Q3Geography·Maps, Lat-Long, Time and Geographical TechniquesPYQ 2024
On June 21 every year, which of the following latitude(s) experience(s) sunlight of more than 12 hours?
1. Equator
2. Tropic of Cancer
3. Tropic of Capricorn
4. Arctic Circle
Select the correct answer using the code given below.
- A1 only
- B2 only
- C3 and 4
- D2 and 4Correct
Explanation
Correct. June 21 is the summer solstice in the Northern Hemisphere. The Tropic of Cancer receives about 13.5 hours of daylight, and the Arctic Circle gets 24 hours of continuous sunlight. The equator stays near 12 hours and the Tropic of Capricorn gets fewer than 12.
Q4Geography·Maps, Lat-Long, Time and Geographical TechniquesPYQ 2022
In the northern hemisphere, the longest day of the year normally occurs in the:
- AFirst half of the month of June
- BSecond half of the month of JuneCorrect
- CFirst half of the month of July
- DSecond half of the month of July
Explanation
Correct. The summer solstice in the Northern Hemisphere occurs around June 20-21, which falls in the second half of June. This is the longest day of the year for the Northern Hemisphere.
Q5Geography·Maps, Lat-Long, Time and Geographical Techniques
Consider the following statements:
Statement-I: The scale of a map is the ratio between the distance on the map and the corresponding distance on the ground.
Statement-II: A map drawn at a scale of 1:25,000 will show more detail than one drawn at 1:250,000.
Which one of the following is correct in respect of the above statements?
- ABoth Statement-I and Statement-II are correct and Statement-II explains Statement-I
- BBoth Statement-I and Statement-II are correct but Statement-II does not explain Statement-ICorrect
- CStatement-I is correct but Statement-II is incorrect
- DStatement-I is incorrect but Statement-II is correct
Explanation
Correct. Statement-I defines map scale correctly. Statement-II is also true — a 1:25,000 map is a larger scale and shows more ground detail than a 1:250,000 map. However, Statement-II does not explain the definition of scale in Statement-I.
Q6Geography·Maps, Lat-Long, Time and Geographical Techniques
Which one of the following correctly describes the numbering system of the Survey of India topographical sheets?
- AIndia is divided into grids of 4° × 4° each designated by a number, further subdivided into 1° × 1° sheetsCorrect
- BIndia is covered by numbered sheets of 15° × 15° grids only
- CEach sheet covers exactly one state of India
- DSheets are numbered sequentially from south to north without a grid system
Explanation
Correct. The Survey of India uses the International Map Series framework where India is divided into 4° × 4° degree sheets (numbered 1 to 136 and beyond), each further subdivided into 16 sheets of 1° × 1° at 1:250,000, and then into 1:50,000 and 1:25,000 sheets.
Q7Geography·Maps, Lat-Long, Time and Geographical Techniques
The contour lines on a topographical map are drawn at intervals of 20 metres. If two adjacent contour lines show values of 200 m and 220 m, and they are 2 cm apart on the map (scale 1:50,000), what is the gradient of the slope?
- A1 in 25
- B1 in 50Correct
- C1 in 100
- D1 in 500
Explanation
Correct. Map distance = 2 cm, scale = 1:50,000, so ground distance = 2 × 50,000 = 100,000 cm = 1,000 m. Vertical rise = 220 − 200 = 20 m. Gradient = 20/1,000 = 1 in 50.
Q8Geography·Maps, Lat-Long, Time and Geographical Techniques
If two places are located on the same longitude but at different latitudes, which of the following statements is correct?
- AThey will have different local times
- BThey will have the same local time but may experience different lengths of dayCorrect
- CThey will have different local times and the same length of day
- DThey will have neither the same local time nor the same length of day
Explanation
Correct. Since both places are on the same meridian, their local (solar) time is identical. However, day length depends on latitude — places closer to the poles have greater seasonal variation in day length than those near the equator.
Q9Geography·Maps, Lat-Long, Time and Geographical Techniques
Which of the following countries does the Prime Meridian (0° longitude) pass through?
1. United Kingdom
2. France
3. Spain
4. Ghana
Select the correct answer using the code given below.
- A1 and 4 only
- B1, 2 and 4 only
- C1, 3 and 4 only
- D1, 2, 3 and 4Correct
Explanation
Correct. The Prime Meridian passes through the United Kingdom (Greenwich), France, Spain, Algeria, Mali, Burkina Faso, Togo and Ghana. All four listed countries are on or very near the 0° line.
Q10Geography·Maps, Lat-Long, Time and Geographical Techniques
Which of the following latitudes experience the phenomenon of 'midnight sun'?
- ABetween the Tropics of Cancer and Capricorn
- BBetween the Arctic Circle and the North PoleCorrect
- CBetween the Equator and the Tropic of Cancer
- DBetween 45° N and 66.5° N
Explanation
Correct. The midnight sun occurs at latitudes poleward of the Arctic Circle (66.5° N) during summer, and poleward of the Antarctic Circle (66.5° S) during their summer. At these latitudes, the sun remains above the horizon for 24 hours during the summer solstice period.
Q11Geography·Maps, Lat-Long, Time and Geographical Techniques
Which of the following is NOT a component of a Geographic Information System (GIS)?
- ASpatial data input and storage
- BAttribute data management
- CPhysical sample collection from the fieldCorrect
- DSpatial analysis and query
Explanation
Correct. Physical sample collection is a field survey activity, not a GIS component. GIS is a computer-based system for capturing, storing, analyzing and displaying geographically referenced data.
Q12Geography·Maps, Lat-Long, Time and Geographical Techniques
Which of the following resolutions in remote sensing describes the ability of a sensor to distinguish between objects that are close together spatially?
- ASpectral resolution
- BTemporal resolution
- CSpatial resolutionCorrect
- DRadiometric resolution
Explanation
Correct. Spatial resolution determines the size of the smallest feature that can be detected. Higher spatial resolution means the sensor can distinguish finer details on the ground.
