Additionally, we get to know about the wind, clouds, atmosphere, respiration, transpiration, and photosynthesis.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-air-around-us-class-6-notes\">Air around Us Class 6 Notes <\/h2>\n\n\n\n<p>All the topics mentioned in the summary have been made into notes format precisely to make it easy for you to understand, learn, and revise them. Let us now explore all important concepts in NCERT Class 6 Science Chapter 11!!\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-properties-of-air\">Properties of Air<\/h3>\n\n\n\n<p>Here are some important properties of air:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Air cannot be seen but it can be felt.<\/li>\n\n\n\n<li>Air occupies space<\/li>\n\n\n\n<li>Air is present all around us<\/li>\n\n\n\n<li>Air does not have any colour&nbsp;<\/li>\n\n\n\n<li>Air is transparent<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-components-of-air\">Components of Air<\/h3>\n\n\n\n<p>Air is a mixture of water vapour, oxygen, nitrogen, <strong>carbon dioxide<\/strong>, and dust and smoke. Here are some key properties of all components of air:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-water-vapour\">Water Vapour<\/h4>\n\n\n\n<p>When air touches a cool surface, it condenses to form water droplets. These droplets were initially in the form of gas in the air. This gaseous substance is called water vapour. This component of air is responsible for the water cycle in nature, which is essential for the life cycle of the Earth.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-oxygen\">Oxygen<\/h4>\n\n\n\n<p>This gas is essential for the existence of life on Earth. It is responsible for <strong>respiration<\/strong>, transpiration, and photosynthesis. All these processes support life on the planet. In addition, oxygen also supports the burning of fossil fuels, candles, etc.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-nitrogen\">Nitrogen<\/h4>\n\n\n\n<p>Nitrogen is the major component of air. It does not support burning. However, it is essential for food production in plans as its presence in soil provides nutrition to fruits and vegetables.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-carbon-dioxide\">Carbon dioxide<\/h4>\n\n\n\n<p>Carbon dioxide is a minor component of air. This gas is used by <strong>plants<\/strong> and animals for respiration. Also, carbon dioxide is required for photosynthesis in plants. However, excess carbon dioxide can cause suffocation and <a href=\"https:\/\/leverageedu.com\/blog\/essay-on-global-warming\/\"><strong>global warming<\/strong><\/a>.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-dust-and-smoke\">Dust and Smoke<\/h4>\n\n\n\n<p>Smoke is produced due to the burning of fossil fuels. It contains carbon dioxide and other gases as well as dust particles. Both dust and smoke are harmful to living organisms and the environment.&nbsp;<\/p>\n\n\n\n<p><strong>You can also learn about the effect of excess dust and smoke in <\/strong><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/essay-on-air-pollution\/\"><strong>Essay on Air Pollution for Students<\/strong><\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-composition-of-air\">Composition of Air<\/h3>\n\n\n\n<p>Air is a mixture of different gases. It contains 78% nitrogen, 215 oxygen, 0.9% argon, 0.04% carbon dioxide, and nearly 1% water vapour. Additionally, the air contains smoke and dust particles.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"Composition of Air\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh5.googleusercontent.com\/3hhacDRk8WT9XnQHfeaEI1tB9q2sdc_fZq7rwUhirdDsB1UojnVgB3Oxe4HuyeQWeakyEezt_key8BtFSyFRBT1VCRBdFGr1BV43X2nVOi4kv4pu30TH4Vd-XSVrGUEVfhuNKd_b0BsFxwJ0XQgYbM8\" ><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-is-oxygen-replaced-in-the-atmosphere\">How is Oxygen Replaced in the Atmosphere?<\/h3>\n\n\n\n<p>Oxygen contributes to the 21% of the air present in the <a href=\"https:\/\/leverageedu.com\/blog\/layers-of-atmosphere\/\"><strong>atmosphere<\/strong><\/a>. All living organisms use this gas for respiration. To balance the composition of oxygen and carbon dioxide in the atmosphere, plants perform photosynthesis. In this biological process, plants inhale carbon dioxide and exhale oxygen. With this process, oxygen is replaced in the atmosphere.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-symbiotic-cycle\">Symbiotic Cycle<\/h3>\n\n\n\n<p>Here is a brief overview of the symbiotic relationship between different organisms or the symbiotic cycle:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Each organism in the environment mutually benefits from each other.<\/li>\n\n\n\n<li>Plants provide us with oxygen and other goods, and we provide them with more than just carbon dioxide; we also benefit them in other ways.<\/li>\n\n\n\n<li>It takes the shape of a cycle. Oxygen and carbon dioxide are recycled in the environment through respiration and photosynthesis.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\"><strong>Also Read:<\/strong> <strong>What is Botany?<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-do-living-organisms-breathe\">How do Living Organisms Breathe?<\/h3>\n\n\n\n<p>Different organisms inhale and exhale air through different processes. Here is how human beings and terrestrial animals, plants, and aquatic animals breathe:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Human Beings and Terrestrial Animals: <\/strong>These organisms inhale oxygen through the nose and mouth and exhale carbon dioxide through the nose. This process takes place in the lungs of animals and humans.<\/li>\n\n\n\n<li><strong>Plants: <\/strong>The green leaves of plants breathe for plants.

All the answers are according to the latest curriculum of this <a href=\"https:\/\/leverageedu.com\/blog\/education-boards-in-india\/\"><strong>education board in India<\/strong><\/a>.<\/p>\n\n\n\n<p><strong>Ques 1: What is the composition of air?<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> Air is made up of oxygen, water vapour, carbon dioxide, nitrogen, and dust and smoke.<\/p>\n\n\n\n<p><strong>Ques 2: Which gas in the air is important for respiration?<\/strong><\/p>\n\n\n\n<p><strong>Ans: <\/strong>Oxygen in the air is important for respiration.<\/p>\n\n\n\n<p><strong>Ques 3: How can you prove that air supports burning?<\/strong><\/p>\n\n\n\n<p><strong>Ans: <\/strong>Put two candles of equal length on a table. Now, light the two candles. After this, cover one lit candle with an inverted glass tumbler. Now, we see that the flame of the covered candle is extinguished after some time. The covered candle gets extinguished because air gets cut when we put a glass tumbler on it as air is required to support burning. Whereas, the open candle continues to burn as it gets a regular air supply.<\/p>\n\n\n\n<p><strong>Ques 4: How will you prove that air is dissolved in water?<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> Fill a container with water. On a tripod stand, slowly warm it up. Examine the interior of the container before the water starts to boil. Inside, we see little bubbles. These bubbles are a result of water containing dissolved air. The air that has been dissolved in the water escapes when it is first heated. The results of this experiment indicate that there is air in the water.<\/p>\n\n\n\n<p><strong>Ques 5: Why does a lump of cotton wool shrink in water?<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> In water, cotton wool lumps shrink because water replaces the air inside them, causing the layers to adhere to one another.<\/p>\n\n\n\n<p><strong>Ques 6: The layer of air around the Earth is called ______________.<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> Atmosphere<\/p>\n\n\n\n<p><strong>Ques 7: The component of air used by green plants for photosynthesis is ____________.<\/strong><\/p>\n\n\n\n<p><strong>Ans: <\/strong>Carbon dioxide<\/p>\n\n\n\n<p><strong>Ques 8: Name five activities that are possible due to the presence of air.<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> Here are the five activities that occur due to air:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Transpiration&nbsp;<\/li>\n\n\n\n<li>Respiration<\/li>\n\n\n\n<li>Photosynthesis<\/li>\n\n\n\n<li>Winnowing<\/li>\n\n\n\n<li>Cloud formation<\/li>\n<\/ol>\n\n\n\n<p><strong>Ques 9: How do plants and animals help each other in the exchange of gases in the atmosphere?<\/strong><\/p>\n\n\n\n<p><strong>Ans:<\/strong> Animals and plants use oxygen from the air for respiration, which also involves the emission of carbon dioxide gas into the atmosphere. In addition, during the process of photosynthesis, green plants also release oxygen gas by utilising carbon dioxide. Consequently, in this way, the exchange of gases in the atmosphere is aided by the cooperation of plants and animals.<\/p>\n\n\n\n<p><strong>Also Read:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-pale-cyan-blue-background-color has-background has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-1-notes-components-of-food\/\"><strong>NCERT Class 6 Science Chapter 1 Notes: Components of Food<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-2-notes-sorting-materials-into-groups\/\"><strong>NCERT Class 6 Science Chapter 2 Notes: Sorting Materials into Groups<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-3-notes-separation-of-substances\/\"><strong>NCERT Class 6 Science Chapter 3 Notes: Separation of Substances<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-4-notes-getting-to-know-plants\/\"><strong>NCERT Class 6 Science Chapter 4 Notes: Getting to Know Plants<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-5-notes-body-movements\/\"><strong>NCERT Class 6 Science Chapter 5 Notes: Body Movements<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-6-notes-the-living-organisms-characteristics-and-habitats\/\"><strong>NCERT Class 6 Science Chapter 6 Notes: The Living Organisms: Characteristics and Habitats<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-7-notes-motion-and-measurement-of-distances\/\"><strong>NCERT Class 6 Science Chapter 7 Notes: Motions and Measurement of Distances<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-8-notes-light-shadows-and-reflections\/\"><strong>NCERT Class 6 Science Chapter 8 Notes: Light, Shadows and Reflections<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/ncert-class-6-science-chapter-9-notes-electricity-and-circuits\/\"><strong>NCERT Class 6 Science Chapter 9 Notes: Electricity and Circuits<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/ncert-class-6-science-chapter-10-notes-fun-with-magnets\/\"><strong>NCERT Class 6 Science Chapter 10 Notes: Fun with Magnets<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Explore Notes of All subjects of CBSE Class 6:-<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/cbse-ncert-notes-class-6-english\/\"><strong>CBSE NCERT Notes Class 6 English<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/cbse-notes-for-history\/\"><strong>CBSE NCERT Notes Class 6 History&nbsp;<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/cbse-notes-class-6-geography\/\"><strong>CBSE NCERT Notes Class 6 Geography<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/discover\/school-education\/cbse-notes-class-6-civics\/\"><strong>CBSE&nbsp;
