Earth as an interconnected system
In this Class 9 Science topic, students explore Earth as an interconnected system in which the atmosphere, hydrosphere, geosphere, and biosphere constantly interact. They learn how energy from the Sun drives weather, climate, and life processes, while matter moves through cycles such as the water and carbon cycles. The topic also develops an understanding of feedback, balance, and how natural events and human activities can affect multiple parts of Earth at once.
