• Solid water – ice is frozen water in the form of ice.
• Liquid water is wet and fluid.
• Water as a gas – vapour is always present in the air around us.

The different sources of water are seas and oceans, fresh water, ground water, snow and ice.
i. Seas and oceans- Saline water also called salt water is water which has a high amount of salt in it. Almost all the water on the Earth is in seas and oceans and is saline.
ii. Fresh water- The water available in streams, rivers and lakes forms the fresh water. It contains only minimum quantities of dissolved salts. All freshwater comes from Precipitation of water vapour present in the air which reaches the inland lakes, rivers
iii. Snow and ice- Water freezes and becomes snow and ice in cold weather. Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow
iv. Ground water- Groundwater is the water that is present below the earth’s surface and is a vast resource of water. Almost 22 percent of water is below the surface land in the form of groundwater. Groundwater returns to the surface again through springs and rivers.
What is water cycle?
The water cycle is the continuous movement of water within the Earth and atmosphere. The liquid water evaporates into water vapour, then it condenses to form clouds, and when the clouds become heavy and are unable to control water in them, they precipitate back to earth in the form of rain and snow. Water in different phases moves through the atmosphere. Thus, water cycle includes four process, evaporation, condensation, precipitation and collection.
Why should we save water?
Living organisms need water to maintain the balance in their bodies. We also use water for cooking, cleaning, washing, etc every day in our home. It is also used for different processes in the factories for making goods. Water is also used for growing crops and other food sources. So water is an essential thing required by us to survive therefore we should not waste water rather we should use it wisely and save it for the future generations.

i. Solute- Any substance that dissolves or is added into a liquid is called a solute. Eg- salt, sugar
ii. Solvent –A liquid (water) in which the solute is added or dissolved is called a solvent. Eg- milk, water

Class 3 EVS Chapter 3 Question and Answers

A safe water storage container should have the following qualities:
• It should be strong with tight fitting lid or cover.
• The container may be of plastic, metal, or ceramic, but the lid must fit tightly.
• Glass is the safest and best way to store liquids as water in glass bottles does not get affected by any flavour from the container, gives it a “purity of taste” as compared to plastic bottles and other options.

When rivers pass through cities, dirt, mud, plastic, paper, oil, garbage, and chemicals mix in the water, making it polluted. The harmful things that make water polluted are called Pollutants. Water pollution can be polluted due to city sewage and industrial waste discharge, contaminants that enter the water supply from soil or groundwater system.
What are the causes of water pollution?
Artificial chemicals, waste products from various industries and factories, insecticides, and pesticides of the farms mix with surface water in the surrounding areas and cause water pollution. People throw garbage directly in water bodies. Drains pour the water directly in water bodies causing pollution. Water is polluted when the industries pour chemicals and other waste materials into the water bodies. People wash their clothes, bathe their animals and take bath themselves which pollutes the water bodies.
What are the harmful effects of water pollution?
Harmful effects of water pollution are as follows:
• Causes fish and other aquatic organisms to die.
• Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.
• It causes typhoid, cholera, hepatitis and various other diseases.
• Destruction of ecosystems
• Harms the crops
Define – Evaporation, Condensation, precipitation
i. Evaporation is the process in which a substance that is in a liquid state changes to a gaseous state due to an increase in temperature or pressure.
ii. Condensation is the process in which a gas changes into its liquid state is called condensation. The water vapour condenses when it is very cold. Water vapour in the warm air, changes back into liquid when it touches the cold surface of glass.
iii. Precipitation is the process in which any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow.
Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle
Why is it important to conserve water?
It is important to conserve water because water is very useful to us. It is our basic requirement which we need for our survival.
