Detailed explanation-1: -From a systems point of view, Earth is essentially a closed system with respect to matter. The functioning of our planet relies on a constant input of energy from the sun. This energy leaves Earth in the form of heat flowing to outer space. From a systems point of view, Earth is an open system with respect to energy.
Detailed explanation-2: -An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
Detailed explanation-3: -It is accepted science that the Earth is an open system for energy. Energy radiates into the Earth’s system, mainly from the sun. Energy is then radiated back into space from the Earth, with the flows being regulated by the Earth’s atmosphere and ozone layer.
Detailed explanation-4: -A open system allows energy, but not matter to be transferred into and out of the system.
