The Earth is mostly considered a closed system because it exchanges energy with its surroundings but not matter. However, it can also be viewed as an open system when considering the input and output of matter through processes like meteorite impacts or atmospheric escape.
Earth is a closed system in terms of matter, meaning that no new matter is added from outside the system. Matter can cycle within the Earth's systems (such as the water cycle or carbon cycle), but it does not enter or leave the planet.
A system is a well-defined group of objects that transfer energy to one another. This transfer can take place as a result of mechanical work, heat, or electromagnetic radiation within the system. Systems can be open, closed, or isolated depending on the exchange of matter and energy with their surroundings.
The hydrological cycle is considered a closed system because water is continuously recycled through evaporation, condensation, precipitation, and runoff. Water enters and exits the cycle naturally, but the total amount of water on Earth remains relatively constant.
Early Earth was likely an open planet, with gases and materials escaping into space due to the planet's lower gravity and lack of a protective magnetic field. This allowed for the loss of volatile elements and the input of materials from the surrounding space, shaping the composition and atmosphere of our planet over time.
Earth is an open system with respect to energy, as it receives energy inputs from the Sun in the form of sunlight and radiates heat back into space. Additionally, Earth is an open system with respect to matter, as it exchanges gases, water, and nutrients with its surroundings through processes like photosynthesis, respiration, and the water cycle.
open: matter and energy can pass freely in and out closed: only energy can pass freely isolated: nothing can pass freely
An air conditioning system an OPEN system
A closed system or an open system. An open can also exchange matter. An Isolated system can exchange neither.
An open system in physics is one that can exchange both energy and matter with its surroundings. This is in contrast to closed systems, which can only exchange energy, and isolated systems, which cannot exchange either energy or matter with their surroundings.
A closed system does not let any matter enter or exit, and no energy enters or exits the system.
Systems can be classified as open, closed, or isolated. Open systems exchange both matter and energy with their surroundings, closed systems only exchange energy, and isolated systems exchange neither. These classifications are based on the extent of interaction between the system and its environment.
Early Earth was an open system because energy and matter such as light energy and meteors were bombarding the Earth.
In an open system,both energy and matter flow.In an closed system only energy flow.In an isolated system neither energy nor matter flow.
An open system is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept (see below). An open system should be contrasted with the concept of an isolated system which exchanges neither energy, matter, or information with its environment.a closed system is isolated from environmental influences. In reality completely closed systems are rare.

In an open system, matter and energy can enter and leave the system, while in a closed system, only energy can enter or leave the system, not matter. Open systems are more interconnected with their surroundings, while closed systems are more isolated.
