Natural ground cover. Y. ou must know…. where water is. h. ow water moves. AND. w. hy water is an important abiotic (nonliving) factor within an ecosystem. Where does water go?. When water falls to Earth, some water soaks into the ground becoming part of groundwater.. Learning objectives.

Explain the structure and processes within the hydrosphere. Explain how water is an energy agent (currents and heat transfer). understand the role of water in weather and atmospheric change. Runoff may be defined as that part of precipitation as well as any other flow contributions which appear in surface streams of either perennial or seasonal nature.. It is the flow collected from a drainage basin appearing at the outlet of the basin or catchment. Reading Assignment: . Chapter 5 of Hartmann GPC. 1. Summary of Surface Energy Balance. Rnet. (.
