Class 5 EVS – Chapter 1: Water: The Essence of Life
NCERT Solutions chapter topic wise Question and answers
Q1. Why is water called the essence of life?
Answer:
Water is essential for all living beings — humans, animals, and plants. All activities of life such as drinking, cooking, washing, cleaning, and farming require water. Without water, life cannot exist on Earth. That’s why water is called the “essence of life.”
Q2. List the main sources of water.
Answer:
- Rivers
- Lakes
- Ponds
- Wells and handpumps
- Rainwater
- Glaciers and ice caps
Q3. What are the three forms of water? Give examples.
Answer:
Water exists in three forms:
| Form | Example |
|---|---|
| Solid | Ice, snow |
| Liquid | River, pond, rainwater |
| Gas (vapor) | Steam, clouds |
Water changes from one form to another through melting, evaporation, and condensation.
Q4. What is the water cycle?
Answer:
The water cycle is the continuous movement of water on Earth through evaporation, condensation, and precipitation.
Steps of the water cycle:
- Evaporation – Sun heats water in rivers, lakes, and oceans, turning it into vapor.
- Condensation – Vapour cools in the air to form clouds.
- Precipitation – Clouds release water as rain, snow, or hail.
- Collection – Rainwater collects in rivers, ponds, lakes, and oceans.
This cycle repeats continuously, maintaining the balance of water on Earth.
Q5. What is groundwater? How is it useful?
Answer:
Some rainwater seeps into the ground and collects in spaces in soil and rocks. This water stored under the ground is called groundwater.
Uses of groundwater:
- Drinking
- Irrigation for crops
- Industrial use through wells, handpumps, and borewells
Q6. How do rivers make land fertile?
Answer:
Rivers carry soil and sand from mountains as they flow. When rivers reach plains, the soil and sand settle, making the land rich and fertile. This helps in growing crops.
Q7. Name some aquatic plants and animals.
Answer:
Aquatic Plants:
- Lotus
- Water hyacinth
- Hydrilla
- Reeds and cattails
Aquatic Animals:
- Fish
- Frogs
- Turtles
- Crabs
- Water birds
Q8. List some uses of water.
Answer:
- Drinking and cooking
- Bathing and washing
- Growing crops and gardening
- Generating electricity (hydropower)
- Industrial purposes
- Transportation by boats and ships
Q9. What are the problems related to water?
Answer:
- Water pollution – rivers, lakes, and ponds are polluted due to garbage and chemicals.
- Wastage of water in households, industries, and farms.
- Deforestation and cemented surfaces stop rainwater from reaching the ground, lowering groundwater.
- Floods in some areas and droughts in others.
Q10. How can we conserve water?
Answer:
- Turn off taps properly and fix leaks.
- Use buckets instead of showers.
- Reuse leftover water for plants or cleaning.
- Collect and store rainwater (rainwater harvesting).
- Avoid dumping garbage into water bodies.
- Plant trees to help recharge groundwater.
Slogan: “Every Drop Counts!”
Q11. Explain why water is important for plants and animals.
Answer:
- Plants need water for photosynthesis and growth.
- Animals need water to drink, stay hydrated, and survive.
- Aquatic animals depend on water for their habitat and life.
Q12. What will happen if water is not conserved?
Answer:
- Rivers and ponds may dry up.
- Crops will not grow, leading to food shortage.
- Animals and humans will face water scarcity.
- Life on Earth will be adversely affected.

3. Long Answer Questions (4–6 lines each)
Q1. Explain the different forms of water with examples.
Answer: Water exists in three forms:
- Solid – Ice or snow, found on mountains and glaciers.
- Liquid – Water in rivers, lakes, and rain.
- Gas (vapour) – Steam or clouds in the atmosphere.
Water changes from one form to another due to heating or cooling.
Q2. Describe the water cycle.
Answer: The water cycle has three main stages:
- Evaporation: Sun’s heat changes water from rivers and oceans into vapour.
- Condensation: The vapour cools and forms clouds.
- Precipitation: Clouds release water as rain, snow, or hail.
This water again flows into rivers and seas. The cycle keeps repeating.
Q3. Write a short note on the journey of a river.
Answer: Rivers begin from mountains or hills where melted snow or rainwater collects.
They flow downwards, carrying soil and stones.
In plains, the river flow slows down and deposits fertile soil.
Finally, rivers join the sea or ocean.
They are a major source of water for people, animals, and crops.
Q4. What steps can we take to save water?
Answer: To save water, we should:
- Turn off taps when not in use.
- Use a bucket instead of a shower.
- Reuse leftover water for plants.
- Harvest rainwater.
- Keep water bodies clean and pollution-free.
- Plant trees to help recharge groundwater.
Q5. What will happen if there is no rain for a long time?
Answer: If it does not rain for a long time:
- Rivers and ponds will dry up.
- Crops will not grow, leading to food shortage.
- Animals and people will face water scarcity.
- The land will become dry and lifeless.
Q6. What are the main causes and effects of water pollution?
Answer: Causes:
