Water Resources: CBSE Class 10 Geography practice questions
Practise 50 questions on Water Resources, free, with an explanation for each answer.
Sample questions
Why is water described as a renewable resource?
- Three-fourths of the Earth is covered with water, so it can never be used up
- It keeps moving through the hydrological cycle, so surface run-off and groundwater are renewed and recharged
- Most of the water on Earth is already fresh enough to drink
- Rain falls equally over every region in every year
Show the answer
B. It keeps moving through the hydrological cycle, so surface run-off and groundwater are renewed and recharged
All water moves within the hydrological cycle, and freshwater from surface run-off and groundwater is continually renewed and recharged. That is what makes it renewable. The other options fail: water covers most of the Earth but only a small part is usable freshwater, and rainfall varies greatly over space and time.
According to the chapter, water scarcity in most cases is caused by
- low rainfall in desert regions alone
- three-fourths of the Earth being covered with water
- the hydrological cycle stopping for some months
- over-exploitation, excessive use and unequal access to water among different social groups
Show the answer
D. over-exploitation, excessive use and unequal access to water among different social groups
Water availability does vary with seasonal and annual rainfall, but scarcity in most cases comes from over-exploitation, excessive use and unequal access among social groups. Believing that only low rainfall causes scarcity is the common mistake; cities with ample resources can also be short of water.
Under the Jal Jeevan Mission, piped water is to be supplied at 55 litres per capita per day (per person per day). A rural family has 5 members. How many litres should it receive in 7 days?
- 385 litres
- 275 litres
- 67 litres
- 1,925 litres
Show the answer
D. 1,925 litres
Per person per day is 55 L, so the family needs L. Traps: forgetting the 5 persons gives 385 L; forgetting the 7 days gives 275 L; adding the numbers gives 67.
