Question (3)

QN0037523

A region receives heavy rainfall but still experiences water scarcity because of high population and intensive irrigation. What is the most likely reason?

(A) Low evaporation
(B) High water demand
(C) Excessive snowfall
(D) Low population density

Correct Answer: B

Explanation:

High population and intensive irrigation increase demand for water and can create scarcity despite good rainfall.

Question (4)

QN0037524

Tube-wells are being used continuously in a village, and the groundwater level is falling every year. Which process best explains this situation?

(A) Extraction is faster than replenishment
(B) Rainfall is increasing
(C) Surface runoff is decreasing
(D) Evaporation has stopped

Correct Answer: A

Explanation:

Continuous extraction of groundwater faster than natural recharge causes groundwater levels to decline.

Question (5)

QN0037525

Which sector is the largest consumer of water in India?

Question (6)

QN0037526

Which measure would most directly reduce dependence on irrigation water in a drought-prone region?

(A) Growing more water-intensive crops
(B) Increasing groundwater extraction
(C) Growing drought-resistant crops
(D) Increasing flood irrigation

Correct Answer: C

Explanation:

Drought-resistant crops require comparatively less water and therefore reduce irrigation demand.

Question (7)

QN0037527

A housing society with a large population uses groundwater through many borewells. What is the most likely long-term effect?

(A) Increase in groundwater level
(B) Groundwater depletion
(C) Increase in rainfall
(D) Reduction in evaporation

Correct Answer: B

Explanation:

Heavy groundwater extraction by a large population can exceed natural recharge and cause depletion.

Question (8)

QN0037528

A town of 4 lakh people uses an average of 100 litres of water per person per day. What is the total daily water requirement?

(A) 4 million litres
(B) 40 million litres
(C) 400 million litres
(D) 4000 million litres

Correct Answer: B

Explanation:

4,00,000 × 100 = 40,000,000 litres, or 40 million litres per day.

Question (9)

QN0037529

If the population of the town in Question 8 increases by 25%, while per-person consumption remains unchanged, what will be the new daily requirement?

(A) 45 million litres
(B) 50 million litres
(C) 55 million litres
(D) 60 million litres

Correct Answer: B

Explanation:

New population = 4,00,000 × 1.25 = 5,00,000. Water requirement = 5,00,000 × 100 = 50 million litres.

Question (10)

QN0037530

Which situation best illustrates unequal access to water as a cause of water scarcity?

(A) All households receiving equal water
(B) Some groups receiving adequate water while others travel long distances
(C) Increase in annual rainfall
(D) Construction of check dams

Correct Answer: B

Explanation:

Unequal distribution and access can create water scarcity for particular sections of society even when water is available in the region.
