Why is earth and example of a system?

Earth is an example of a system because it comprises interconnected components—such as the atmosphere, hydrosphere, lithosphere, and biOSphere—that interact with each other in various ways. These interactions create complex processes, such as climate regulation, nutrient cycling, and energy flow. Furthermore, Earth exhibits feedback mechanisms that maintain balance, demonstrating the characteristics of a dynamic system. Overall, the interconnectedness and interdependence of its parts illustrate how Earth operates as a cohesive whole.
