Chapter 14: Water
These NCERT Class 6 Science Chapter 14 notes explain the importance of water for life on Earth. The chapter introduces students to different sources of water, the states of water, and how water is continuously reused through the water cycle.
NCERT Class 6 Science Chapter 14 – Water helps students understand processes like evaporation, condensation, and precipitation, which are essential for rainfall. It also explains the growing problem of water scarcity and the need for conservation of water, especially in the Indian context.
This chapter develops awareness about natural resources and environmental responsibility, which is very important for young learners.
1. Importance of water
- Water is essential for all living beings
- Water is used for drinking and cooking
- Water is used for bathing and cleaning
- Water is required for agriculture
- Without water, life on Earth is not possible
2. Sources of water
- Natural sources include rain, rivers, lakes, ponds
- Seas and oceans are also sources of water
- Man-made sources include wells and tubewells
- Canals and dams store and supply water
- Different regions depend on different sources
3. States of water
- Water exists in three states
- Ice is the solid form of water
- Water is the liquid form
- Water vapour is the gaseous form
- Change in temperature changes the state of water
4. Water cycle
- Water cycle is the continuous movement of water
- It occurs between Earth and atmosphere
- Evaporation changes water into vapour due to heat
- Condensation forms clouds from cooled vapour
- Precipitation brings water back as rain, snow, or hail
5. Forms of precipitation
- Rain is the most common form
- Snow occurs in cold regions
- Hail falls as small ice balls
- All forms return water to the Earth’s surface
- Precipitation completes the water cycle
6. Uses of water
- Water is used for domestic purposes
- Water is required for agriculture and irrigation
- Water is used to produce hydroelectric power
- Water is used for transport
- Water is essential for industries
7. Scarcity of water
- Water scarcity means shortage of water
- It is caused by overuse of water
- Pollution reduces usable water
- Uneven rainfall causes water shortage
- Scarcity leads to droughts and water crisis
8. Conservation of water
- Conservation means careful use of water
- Water should not be wasted
- Rainwater harvesting helps store rainwater
- Reusing water reduces shortage
- Saving water ensures future availability
9. Importance of this chapter
- Explains availability of water on Earth
- Highlights need for water conservation
- Builds base for environment studies
- Helps understand climate-related topics
- Important for NCERT, BPSC, and UPSC foundation
10. Important keywords and definitions
- Water cycle: Continuous movement of water between Earth and atmosphere
- Evaporation: Change of water into vapour due to heat
- Condensation: Change of water vapour into liquid water
- Precipitation: Falling of water as rain, snow, or hail
- Conservation: Careful use of natural resources
- Rainwater harvesting: Collection and storage of rainwater
Understanding NCERT Class 6 Science Chapter 14 is essential to learn how water supports life and why it must be used carefully. The chapter highlights the importance of the water cycle in maintaining a constant supply of water on Earth.
The ideas discussed in Water form the foundation for learning about environment, climate, and sustainability.
