continued Lesson 2 Interactions of Earth Systems (continued) 22 Explain five processes that occur within the water cycle NGSSS Check How do Earth systems interact in the water cycle? SC6E74 Water moves between the hydrosphere, cryosphere, atmosphere, biosphere, and geosphere through the Process Evaporation Transpiration Respiration Explanation Liquid water changes into gas Plants release water vapor through their pores Animals release water vapor from their lungs when they breathe Copyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc Copyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc processes of evaporation, condensation, transpiration, and precipitation Changes in the Atmosphere 24 NGSSS Check How does weather show interactions of Earth systems? SC6E74 The hydrosphere provides much of the water for cloud formation and precipitation in the atmosphere Air masses take on the characteristics of the area over which they form, such as a hot, dry desert Condensation Precipitation Describe factors that influence weather Factor Air temperature Air pressure Wind Humidity Description Relate how weather is influenced by conditions in the geosphere and the hydrosphere Accept all reasonable responses Sample answer: Air masses take on the characteristics of the areas over which they form Therefore, weather is determined by an air mass s formation over land or water and the warmth or coolness of that land or water Water vapor changes to liquid water Moisture falls from clouds to Earth s surface average amount of energy produced by the motion of air molecules the force exerted by air molecules in all directions the movement of air caused by differences in air pressure the amount of water vapor in a given volume of air Our Planet Earth 43 Study Guide Study Guide Our Planet Earth 43

SC6E74 The atmosphere, biosphere, and hydrosphere interact with the geosphere through weathering, erosion, and deposition Uplift Weathering Erosion Deposition Compaction Cementation Large bodies of Earth material are moved to higher elevations Factors in the atmosphere, the hydrosphere and the biosphere break rock into sediment Wind, water, and glaciers carry sediment to new locations Eroded sediments are deposited in new places The weight of layers of sediment presses down on layers below Minerals from groundwater crystallize between grains of compressed sediment and cement them together Infer why the atmosphere, the biosphere, and the hydrosphere do not influence metamorphic rock formation Metamorphic rock forms deep beneath Earth s surface Analyze It Suppose you are walking to school in the rain You notice muddy water running down a hill into an animal s burrow Explain the interactions in this example between each of the Earth systems Accept all reasonable responses Sample answer: Weather, which occurs in the atmosphere, is causing rain to fall The water, part of the hydrosphere, is carrying sediment down the hill; the sediment and hill are both part of the geosphere The sediment and water in the animal s burrow will cause the animal, part of the biosphere, to have to repair its home As it digs, the animal is changing geosphere Our Planet Earth 45 Study Guide Study Guide Our Planet Earth 45
