Question

1) What makes the Earth a closed system?

Answer 1

Closed Systems

The earth system as a whole is a closed system. ... Earth in turn emits radiation back out to space across the system boundary. Hence, energy passes across Earth's system boundary, but not mass, making it a closed system. The interface between systems is not always easy to identify, others more so.
