Question

how can the earth be considered a closed system when it comes to matter? the earth constantly exchanges matter with other celestial bodies. matter on earth is constantly increasing due to human activities. the total matter on earth remains constant, with no matter entering or leaving.

Explanation:

A closed system in terms of matter is one where matter does not enter or leave. The Earth has a relatively constant amount of matter. While there are some small - scale exchanges (like meteorites adding a tiny amount of matter and some gas escaping the atmosphere), overall, the total matter on Earth remains approximately constant. Human activities do not create new matter (they just transform existing matter), and the exchanges with other celestial bodies are negligible compared to the total amount of matter on Earth.

Answer:

The total matter on Earth remains constant, with no matter entering or leaving.
