Description
Summative unit assessment covering ecosystems and the hydrosphere: water distribution, the water cycle and residence time, ocean currents and climate, groundwater and watersheds, human impacts on water quality, photosynthesis, food webs and energy flow, trophic levels and the 10% rule, and biomes.
Learning Objectives
-
Describe how water is distributed on Earth and explain why freshwater is a limited resource
-
Explain the processes of the water cycle and the concept of residence time
-
Describe how surface and deep ocean currents form and affect climate
-
Explain how groundwater forms and moves, describe watersheds, and analyze human impacts on water quality
-
Explain photosynthesis using the equation CO2 + H2O + sunlight -> sugar + O2, model energy flow through food webs, and apply the 10% rule
