Elements of the atmosphere

In this Class 11 Geography topic, students study the main components of the atmosphere and how they shape Earth’s environment. It explains the role of gases such as nitrogen, oxygen, carbon dioxide and water vapour, along with dust particles and aerosols. Students also connect atmospheric composition with temperature, pressure, humidity, clouds and weather, building a foundation for understanding the composition and structure of the atmosphere.
