1. Temperature drives water movement in some lakes.
2. Tropical coral reefs generally exist in relatively shallow areas of the ocean.
3. The lowest levels of dissolved oxygen in a stream are generally found in its turbulent headwaters.
4. All wet lands have soils that dry out periodically.
5. Wetlands have slow water movement or no water movement and no turnover.
