That means that chemicals don't leave Earth, or come to Earth, in significant quantities - whereas energy does.
thermal energy is not transferred to the environment.
Total amount of mass energy in a closed system.

With respect to matter, Earth is a closed system and with respect to energy, Earth is an open system.
Because no significant amount of matter enters and leaves Earth. Note, however, that with respect to energy, Earth is NOT a closed system. We can't live without the energy (radiation) from the Sun - and the corresponding cooling-off radiation into space.
The laws of nature would make this impossible, some energy always escapes.
In a closed system, neither the energy or matter changes. (Study Island)

Mainly with respect to energy.
No, the roller coaster is not the only example of a closed energy system.
In a closed system, their sum is constant.

Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
