Air—something we can’t live without but often take for granted. 🌬️ In NCERT Solutions for Class 7 Geography Chapter 4, students will discover the essential role air plays in supporting life on Earth. From keeping us cool on a hot day to providing oxygen for our lungs, air is more than just invisible stuff. It’s one of Earth’s unsung heroes!
The chapter covers the composition of air, which is mostly nitrogen and oxygen, along with small amounts of other gases like carbon dioxide and argon. Students will also learn about the layers of the atmosphere, such as the troposphere, stratosphere, and thermosphere. It’s like an onion—just with way more layers and no tears! 🧅
One interesting topic is the wind—air in motion. Wind helps spread seeds, moves weather patterns, and even generates energy through windmills! 🌬️ But students will also learn that air pollution is a real problem. Factories, vehicles, and burning fuels can release harmful gases into the air, making it difficult for humans and animals to breathe. It’s like giving the Earth a bad cold. 🤧
By the end of the chapter, students will have a new appreciation for air, as well as a deep understanding of how essential it is to all living things. 💨
