In terms of matter and resources, the Earth is essentially a closed system, because matter and resources are fixed.
In terms of energy, the Earth is an open system, because there is a balanced transfer of energy. (The energy radiates into the Earth's system, from the Sun and then it is radiated back into space from the Earth. The flows of energy are regulated by the Earth's atmosphere and ozone layer.)
