FAQs on Activity: Is Air Present Everywhere Around us? Video Lecture - Science Class 6

1. Is air present everywhere around us?
Ans. Yes, air is present everywhere around us. It is a mixture of gases that surround the Earth and fills the atmosphere. We cannot see air, but we can feel its presence through wind and by observing its effects on objects.
2. What is air made up of?
Ans. Air is made up of various gases, primarily nitrogen (about 78%), oxygen (about 21%), and traces of other gases such as carbon dioxide, argon, and water vapor. These gases are essential for various life processes and maintain the balance of the Earth's atmosphere.
3. How does air help us breathe?
Ans. When we breathe, we inhale air into our lungs. The oxygen present in the air is essential for our body's cells to produce energy through respiration. Oxygen from the air is transported to our body tissues through the bloodstream, and carbon dioxide, a waste product, is expelled when we exhale.
4. Can air quality affect our health?
Ans. Yes, the quality of the air we breathe can significantly impact our health. Poor air quality, caused by pollutants such as smoke, dust, and chemicals, can lead to respiratory problems, allergies, and even more severe conditions like asthma and lung diseases. It is important to ensure clean and fresh air to maintain good health.
5. Can air pollution be reduced?
Ans. Yes, air pollution can be reduced through various measures. Some effective ways to reduce air pollution include using cleaner energy sources, such as renewable energy, promoting public transportation, reducing industrial emissions, planting trees, and implementing strict regulations on pollutant emissions. Everyone's collective effort is crucial in improving air quality and protecting the environment.
