Earth is an open system. If you only consider matter, no significant amount of matter comes to Earth or leaves it, so it may be considered closed for all practical purposes. However, there is also the all-important energy; a large amount of energy reaches Earth from the Sun, and is later radiated back into space.

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 that never be self-contained regardless of matter.
Scientists consider Earth a essentially closed system because it exchanges very minimal matter with its surroundings. Though energy from the sun enters and leaves Earth, the actual physical material of Earth is largely self-contained. This allows scientists to study the interactions of different components within this closed system.
Early Earth was an open system because energy and matter such as light energy and meteors were bombarding the Earth.
The Earth is essentially a closed system in terms of matter because very little matter enters or leaves it. While energy from the sun does enter the Earth, matter such as air, water, and rocks primarily remain on the planet. However, the Earth is not a closed system when considering energy because it receives energy from the sun and releases energy back into space.
Earth is essentially not a closed system. It receives energy from the sun and looses energy as it radiates heat into space.
Because no significant amount of matter enters and leaves Earth. Note, however, that with respect to energy, Earth is NOT a closed system. We can't live without the energy (radiation) from the Sun - and the corresponding cooling-off radiation into space.
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.
