1.4 PART IV: SOILS, ECOSYSTEMS, AND BIOMES Energy enters the biosphere through conversion of
solar energy by photosynthesis in the leaves of plants. Soil is the essential link among the lithosphere, plants, and the rest of Earth’s physical systems. Thus, soil helps sustain life and is a bridge between Parts III and IV of this text. Together, soils, plants, animals, and the physical environment make up ecosystems, which are grouped in biomes.

1.2 PART II: WATER, WEATHER, AND CLIMATE SYSTEMS
Earth is the water planet. Part II describes the distribution of water on Earth, including water circulation in the hydrologic cycle. Part II also describes the daily dynamics of the atmosphere as it interacts with the hydrosphere to produce weather. Outputs of the water–weather system range from climate patterns to our water resources. Part II concludes with an examination of global climate change, the impacts that are occurring, and forecasts of future changes.
