3. Which of the following statements is “true”? (a) Water vapour is present in the air only during the monsoon. ( ) (b) Water evaporates into the 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. ( ) Solution: a) False b) False c) True d) False e) True 4. Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how? Solution: Spreading uniform near an anghiti or heater will help because it increases the rate of evaporation due to heat.NCERT Solutions For Class 6 Science Chapter 9
5. Take out a cooled bottle of water from the refrigerator and keep it on a table. After some time, you notice droplets of water around it. Why? Solution: This is because the surface of the air around the bottle cools down and air condenses around the bottle. 6. To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet. Solution: The air we breathe out contains water vapour which condenses on the surface of the spectacles. So, the glass becomes wet, and with the help of a small number of water molecules, it becomes easier to clean the spectacles. 7. How are clouds formed? Solution: The process of condensation plays an important role in bringing water back to the surface of the earth. As we go higher from the surface of the earth, it gets cooler. When the air moves up, it gets cooler and cooler. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in the air and appear to us like clouds.NCERT Solutions For Class 6 Science Chapter 4
8. When does a drought occur? Solution: If it does not rain for two or more years, water is lost from the soil due to evaporation and transpiration. Since it is not being brought back by rain, the soil becomes dry. The level of water in ponds and wells of the region goes down, and some of them may even dry up. Groundwater may also become scarce; this may lead to drought.NCERT Solutions for Class 6 Science Chapter 10
Water Sources There are numerous sources of water, depending on where people find it convenient to access. These sources include ponds, lakes, wells, rivers, seas, and oceans. However, not all water sources are suitable for drinking. Therefore, water is collected from these sources and then purified in different plants to make it suitable for drinking. NCERT Class 6 Science Chapter 14 on Water explains how people in both urban and rural areas use and consume water. Water Cycle Wells offer underground water, which is widely accessible. Ponds, rivers, and lakes also serve as important water sources for living organisms. However, rivers may dry up in certain areas due to factors such as dam construction, excessive water usage, or insufficient rainfall. This is the focal point of Class 6 Science Chapter 14, which explores the water cycle. The water cycle involves the essential processes of evaporation and condensation, simplifying life. Evaporation primarily transforms water into a gaseous state, known as vapour. Condensation, on the other hand, converts vapours back into water molecules. Under the influence of intense heat, water from diverse Earth sources evaporates over time. The water in its gaseous form creates clouds, which eventually condense and return the water to the land. This continuous process is referred to as the water cycle. For a more detailed understanding of this concept, you can refer to NCERT Solutions for Class 6 Science.NCERT Solutions for Class 6 Science Chapter 11
Transpiration According to Ncert Class 6 Science Chapter 14, transpiration is when water evaporates from surfaces and goes into the air. Plants are part of the water cycle. The water cycle helps us use ocean water. Using ocean water directly isn't possible because it's salty. Evaporated water separates from salt to make clouds. Warm air goes up, and cold air makes saturation and condensation, forming water droplets. Clouds gather and cause rainfall over Earth's water sources, like lakes, ponds, and rivers. This rainfall fills these sources for human and animal needs. Soil absorbs rainwater, feeding groundwater. To know more about the water cycle, check NCERT Science book Class 6 Chapter 14 solutions. States of Water Ice from the freezer or snow on mountain peaks is just water in a solid form. People can create ice by freezing water in a freezer. Snow occurs naturally in places with very cold winters, and it comes from tiny water droplets in clouds that fall as snow. The water we get from taps is in a liquid state, and we consume it in that form. The gaseous state of water is commonly known as water vapour or steam. Water vapour naturally exists in the air, and since it is odourless and colourless, we can't smell or see it. However, humans can produce steam, and it becomes visible when released in large amounts. For instance, if you boil water in a container, and it gets too hot, you'll see steam rising. The Water chapter in Class 6 explains each state of water clearly, providing information available in the solutions.NCERT Solutions for Class 6 Science Chapter 5
