Quizplus · Accepted Answer

The Earth system is indeed composed of the hydrosphere (all of the water on Earth), lithosphere (the rigid outer part of the Earth, consisting of the crust and upper mantle), biosphere (the regions of the surface, atmosphere, and hydrosphere of the Earth occupied by living organisms), and atmosphere (the envelope of gases surrounding the planet).
