4 The Water CycleThe movement of water among oceans, atmosphere, land, and living things.Precipitation- water moving from atmosphere to landEx: rain, snow, sleet, hail91% falls into the ocean, 9% on land renews fresh water supply
5 The Water CycleEvaporation- water moving from the land to the atmosphereThe sun’s heat causes water to change from liquid to vaporCondensation- water vapor becoming liquid again due to cool atmosphereTranspiration- water moving from living things back into the atmosphereEx: evaporation from leaves, perspiration from humans
6 The Water CycleGround Water- precipitation that seeps into the ground and is stored in underground caverns and porous rockProvides water for the soil, streams, rivers, and oceansOur water supply is not getting larger so we must protect our fresh water from pollution!!
9 The Carbon CycleThe movement of carbon from the environment into living things and back againCarbon is essential to all living things because it is part of our molecules.
10 The Carbon CyclePhotosynthesis- carbon moves from the environment into living thingsPlants use carbon dioxide from the air to make sugarAnimals get carbon from eating plantsRespiration- carbon moves from living things back to the environmentSugar molecules are broken down to release energy and carbon dioxide is given off when we exhale
11 The Carbon CycleDecomposition- carbon moving from dead organisms back to the environmentFungi and bacteria decompose dead organismsCombustion- the process of burning fuelBurning fossil fuels releases carbon back into the atmosphere
14 The Nitrogen CycleThe movement of nitrogen from the environment to living things and back again.78% of our atmosphere is nitrogen gasNitrogen fixation- the process of bacteria changing nitrogen gas into usable nitrogen for plantsAnimals get nitrogen from eating plantsOther bacteria decompose dead animals and animal waste and return nitrogen to the atmosphere
