With respect to matter, Earth is a closed system and with respect to energy, Earth is an open system.
An open ventilation system simply lets the crankcase fumes vent into the atmosphere. A closed system reburns the crankcase fumes via the pcv valve.
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
The light bulb is a closed system: no mass transfer.
