True.

The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.

Even though the earth system is a closed system, it self regulates through the subsystems  such as the water cycle and  carbon cycle.

The earth system is characterized by numerous overlapping cycles in which matter is recycled  over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
