The light bulb is a closed system: no mass transfer.
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.
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.
Closed System
The biosphere is considered an open system because it interacts with its surroundings through the exchange of energy and matter. It receives input of energy from the sun and cycles materials such as carbon, nitrogen, and water with other Earth systems.
