Here are the best descriptions for each cycle:
- Hydrologic - it's all about water
- Rock - erosion, deposition, metamorphism
- Tectonic - subduction, uplift, and mantle convection
- Carbon - photosynthesis and respiration
- Nitrogen - housed mostly in rock material
- Phosphorus - it's all about special bacteria
This matches each cycle with the most relevant description based on their fundamental processes and characteristics.
