It depends upon how "closed" and how "open."

The components of most systems on earth remain on earth. In this sense, the earth is a closed system.

The exceptions to this rule fall into three different areas:
The influx of "extra-terrestrial" materials that hit the earth or burn up in the atmosphere.
The influx of radiation (but especially from the sun).
The leak of atmospheric gases from the upper atmosphere.
So option 3 is correct.
