Earth System

The Earth system refers to the interconnected set of physical, chemical and biological components of the planet – including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere – that interact through exchanges of energy and matter. These components operate as a dynamic system shaped by processes such as atmospheric circulation, ocean currents, biogeochemical cycles and tectonic activity. Understanding the Earth system is central to studying climate, environmental change and the interactions between natural processes and human activity.
