Explain an open, closed, and isolated system.

An open system is a system that has external interactions.
a closed system is a physical system that does not allow certain types of transfers in our out of the system.
an isolated system obeys the conservation law that its total energy- mass stays constant.

Open system - system in which mass or energy can be lost to or gained from the environment.

closed system - system that does not exchange any matter with its surroundings and is not subject to an external force

isolated system - it can be:
A. a physical system that is so far removed from other systems that it does not interact with them. or
B. a thermodynamic system that is enclosed by rigid immovable walls through which neither matter nor energy can pass through.

hope this helps :)

Depending on how the continental plates move it can cause a continental scale shift.
