Open systems are systems that exchange both energy and matter with their surroundings. This means that within an open system, materials and energy can flow in and out, allowing for dynamic interactions with the environment.
Closed systems are systems that exchange energy but not matter with their surroundings. They can gain or lose energy, such as heat or light, but the matter contained within remains constant.
Isolated systems are systems that do not exchange either energy or matter with their surroundings. They are completely self-contained, with no transfer of any kind across their boundaries.
Earth as a closed system functions overall as a system that exchanges energy but not matter with its surroundings. This means Earth receives energy from the Sun and radiates energy back into space, but matter remains largely contained within the planet.
Open systems are characterized by their ability to exchange both energy and matter with their environment. This exchange allows for complex interactions and processes, such as volcanic eruptions or atmospheric circulation.
