D2.Geo.4.9-12 Interactions between human and physical systems
Analyze relationships and interactions within and between human and physical systems to explain reciprocal influences that occur among them.
Why water teaches this standard well
Water systems supply ready examples of reciprocal human-physical interaction: groundwater pumping causes land subsidence that raises flood risk, dams reshape the rivers that once determined where cities grew, and falling reservoir levels force new policy. Analyzing a basin such as the Colorado shows influence flowing in both directions between people and the physical system.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
