Water Resources Class 10 MCQ

Water Scarcity and Water Conservation

Question 1. What percentage of the Earth’s surface is covered with water?
a) 25%
b) 50%
c) 75%
d) 100%


Answer

c) 75%


Question 2. By 2025, how many people are predicted to live in absolute water scarcity?
a) Nearly 1 billion
b) Nearly 2 billion
c) Nearly 3 billion
d) Nearly 4 billion

Answer

b) Nearly 2 billion
Nearly 2 billion people are predicted to live in absolute water scarcity by 2025.
Absolute water scarcity is defined as a situation where the annual per capita renewable water availability is less than 1,000 cubic meters. This means that there is not enough water to meet the basic needs of people, such as drinking, sanitation, and agriculture.


Question 3. What is the main source of freshwater?
a) Surface runoff and groundwater
b) Oceans and seas
c) Ice caps and glaciers
d) Rivers and lakes

Answer

a) Surface runoff and groundwater
Oceans and seas are saltwater, so they are not considered to be freshwater sources. Ice caps and glaciers are also considered to be freshwater sources, but they are not as accessible as surface runoff and groundwater. Rivers and lakes are also freshwater sources, but they are not as large as surface runoff and groundwater.
So the main source of freshwater is surface runoff and groundwater.


Question 4. What is the main reason for water scarcity?
a) Low rainfall or drought-prone regions
b) Overpopulation
c) Pollution
d) All of the above

Answer

d) All of the above
Low rainfall or drought-prone regions: In areas where there is not enough rainfall, water scarcity is a major problem. This is because there is not enough water to meet the needs of people and the environment.
Overpopulation: As the population grows, the demand for water also grows. This can lead to water scarcity, especially in areas where water resources are already limited.
Pollution: Pollution can contaminate water sources, making them unfit for human consumption or use in agriculture. This can also lead to water scarcity, as people and businesses are forced to find other sources of water.
In addition to these three main reasons, there are other factors that can contribute to water scarcity, such as climate change, inefficient water use, and poor water management.


Question 5. What is the traditional method of storing drinking water in Rajasthan?
a) Wells
b) Underground tanks or tankas
c) Ponds
d) Reservoirs

Answer

b) Underground tanks or tankas
Rajasthan is a desert state, so water is a precious resource. Tankas are a way to store water during the rainy season so that it can be used during the dry season. Tankas are typically made of mud or stone, and they are lined with lime to prevent water from seeping out. They are usually located underground, which helps to keep the water cool and prevent it from being contaminated.

Wells, ponds, and reservoirs are also used to store water in Rajasthan, but tankas are the most traditional method.


Question 6. What is the traditional method of rainwater harvesting in the Western Himalayas?
a) Guls or kuls
b) Tankas
c) Johads
d) Khadins

Answer

a) Guls or kuls


Multipurpose River Projects

Question 7. What is the main purpose of multi-purpose river projects?
a) Control floods
b) Generate electricity
c) Provide irrigation
d) All of the above

Answer

d) All of the above

The main purpose of multi-purpose river projects is to control floods, generate electricity, and provide irrigation.
Multi-purpose river projects are large-scale water management projects that involve the construction of dams, reservoirs, and canals. These projects are designed to achieve multiple objectives, such as:

Controlling floods: Dams and reservoirs can help to control floods by storing excess water during the rainy season and releasing it slowly during the dry season.
Generating electricity: Dams can be used to generate hydroelectricity, which is a clean and renewable form of energy.
Providing irrigation: Canals can be used to distribute water for irrigation, which is essential for agricultural production.


Question 8. What is a major disadvantage of multi-purpose river projects?
a) They cause soil erosion
b) They induce earthquakes
c) They cause water-borne diseases and pests
d) All of the above

Answer

d) All of the above


Question 9. True or False: Multi-purpose projects have been successful in controlling floods at the time of excessive rainfall.
a) True
b) False

Question 10. What happens due to sedimentation in the reservoir of dams?
a) It triggers floods
b) It reduces the capacity of the dam
c) It causes the dam to break
d) It pollutes the water

Answer

b) Sedimentation can reduce the capacity of the dam by filling up the reservoir and reducing the amount of water that can be stored.


Question 11. What is a major environmental impact of multi-purpose river projects?
a) Deforestation
