both. For everything except energy, it's closed.

For energy (i.e. the sun's input, radiation into space at night) it's open.

One definition of a closed system is a system that can exchange energy with it's environment but not matter. Therefore the earth is a closed system by this logic.

This is disputable! Good question!!! The earth is generally accepted to be a largely closed system as far as matter goes (although there is a small amount of particles entering and exiting the earth at any given time). But the earth is gaining and losing energy all the time so it is definitely an open system as far as energy is concerned.

It's considered a closed system because the water just keeps getting reused by evaporation,precipitation,condensation, and runoff.
