User: Name statement(s) that best describe Earth's hydrologic, rock, and tectonic cycles.

Weegy: As the Earth is essentially a closed system with respect to matter, we can say that all matter on Earth cycles . Biogeochemical cycles: the movement (or cycling) of matter through a system in general... [ we can subdivide the Earth system into: atmosphere hydrosphere lithosphere biosphere by matter we mean: elements (carbon, nitrogen, oxygen) or molecules (water) so the movement of matter (for example carbon) between these parts of the system is, practically speaking, a biogeochemical cycle The Cycling Elements: macronutrients : required in relatively large amounts "big six": carbon hydrogen oxygen nitrogen phosphorous sulfur other macronutrients: potassium calcium iron magnesium micronutrients : required in very small amounts, (but still necessary) boron (green plants) copper (some enzymes) molybdenum (nitrogen-fixing bacteria) Generalized Biogeochemical Cycle: Biogeochemical cycles are part of the larger cycles that describe the functioning of the whole Earth (not just the surface parts) Geological cycle consists of: tectonic cycle rock cycle hydrologic cycle biogeochemical cycles We will focus on the hydrologic cycle and the biogeochemical cycles. ]
