NCERT Solutions for Class 6 Science Chapter 14 – Water – NCERT Exercises
Question 1:-
Fill up the blanks in the following:
(a) The process of changing of water into its vapour is called ________.
(b) The process of changing water vapour into water is called _______.
(c) No rainfall for a year or more may lead to ________ in that region.
(d) Excessive rains may cause _______.
Answer 1: –
(a) The process of changing of water into its vapour is called evaporation.
(b) The process of changing water vapour into water is called condensation.
(c) No rainfall for a year or more may lead to drought in that region.
(d) Excessive rains may cause floods.

Question 3:-
Which of the following statements are “true” ?
(a) Water vapour is present in air only during the monsoon. ( )
(b) Water evaporates into air from oceans, rivers and lakes but not from the soil.( )
(c) The process of water changing into its vapour, is called evaporation.( )
(d) The evaporation of water takes place only in sunlight.( )
(e) Water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler.( )
Answer 3:-
(a) False
(b) False
(c)True
(d) Flase
(e) True
Question 4:-
Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?
Answer 4: –
Evaporation increases in presence of heat. Hence, spreading the uniform near an anghiti or heater will help in drying the uniform quickly.
Question 5:-
Take out a cooled bottle of water from refrigerator and keep it on a table. After some time you notice a droplets of water around it. Why?
Answer 5: –
We notice droplets of water around a cooled bottle of water from refrigerator when taken out because water vapours from air come in contact with cold air around the bottle and lose heat converting them into liquid form. This process is also called condensation.
Question 6:-
To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet.
Answer 6: –
When we breathe out on glasses, the surface of the glass becomes cooler than its surroundings. When water vapours from the environment come in contact with this surface, they undergo condensation and convert to liquid form, making the surface wet.
Question 7:-
How are clouds formed?
Answer 7: –
As the height from the surface increases, the temperature of the earth reduces. When the air moves up, it loses heat and at sufficient height, cools enough to convert from vapour to small water droplets. These tiny droplets remain floating in air and appear to us as clouds. This indicates that condensation plays an important role bringing evaporated water back to earth.
Question 8:-
When does a drought occur?
Answer 8: –
When there is no rain for a long time in an area, land loses all its water through evaporation and transpiration. This leaves the land dry and lifeless. This situation is called drought.
NCERT Solutions for Class 6 Science Chapter 14 – Water – Video Explanation
We use water everyday to perform various activities. Without this, life cannot be possible. Cooking, cleaning utensils, washing clothes and bathing, water is required all the time.
Water is used in industries for producing almost all the things that we use. In this lesson, you will learn about the sources of water and its significance. You will also learn methods to conserve water.

Important Terms Relevant to understand NCERT Solutions for Class 6 Science Chapter 14 – Water: –
Clouds: Tiny droplets of water floating in sky, formed due to condensation are called clouds.
Hail: When rain droplets freeze and precipitate, it is known as hail.
Condensation: The conversion of water vapour into liquid form due to loss of heat is called condensation.
Ocean: A large body of water, from which water evaporates to bring fresh water to lands in the form of rain is called an ocean.
Drought: When there is no rain for a long time in an area, land loses all its water through evaporation and transpiration. This leaves the land dry and lifeless. This situation is called drought.
Rainwater harvesting: Collecting rainwater in different ways and storing it for later use is called rainwater harvesting. It is a method of conservation of water. Rooftop rainwater harvesting and roadside drains are common methods of rainwater harvesting.
Evaporation: The conversion of water into its vapour is called evaporation. It occurs when heat is applied to the liquid.
Snow: When water vapours freeze to form white ice crystals, it forms snow.
Flood: When due to excess rainfall and due rise in levels of rivers and pond, water flows into the lands, it is called flood. Every year, floods cause a lot of damage.
Water vapour: When water evaporates from liquid to gas, the gaseous from of water is called water vapour.
Ground water: A part of rainwater gets absorbed by the ground and seeps down to form ground water.
Water cycle: The circulation of water between oceans, land, and rain is called water cycle. Water is evaporated from oceans. Then it comes down to the land in the form of rains, hail or snow and eventually goes back to the ocean through rivers.
