Biogeochemical Cycles and Interrelationship Activity
WATER CYCLE For each point below add the activity to the water cycle where it belongs using a short description and a simple illustration. In bold letters mark whether the activity REDUCES the amount of water; INCREASES the amount of water; DEGRADES the water quality. Note if this human activity shows up in any other biogeochemical cycle. Work on your summary. How are human activities affecting the water cycle? (8 activities) During the past 100 years, we have been intervening in the earth?s current water cycle in four major ways. We withdraw large quantities of fresh water from streams, lakes, and underground sources especially in heavily populated areas.
