Layers of the atmosphere

वायुमंडल की परतें

In Class 11 Geography, this topic explains how Earth’s atmosphere is arranged into distinct layers—troposphere, stratosphere, mesosphere, thermosphere and exosphere—and how temperature, pressure, density and composition change with altitude. Students connect the troposphere with weather and climate, the stratosphere with the ozone layer, and the upper layers with satellites and auroras. The lesson builds a clear foundation for understanding the composition and structure of the atmosphere and its importance for life and human activities.
