Where Water is Found Atmosphere- Precipitation Organisms The Water Cycle Introduction to Agriculture, Food, and Natural Resources Unit 4 Lesson 4.3 Water World Where Water is Found Atmosphere- Clouds Water vapor Precipitation Rain Snow Sleet Hail Organisms All living things Earth’s surface Rivers Lakes Streams Snow/ice Groundwater Water is found nearly everywhere. The most obvious locations of water are lakes, rivers, streams, and oceans. These locations are all called surface water. There are large quantities of water stored underground, which is called groundwater. Additionally there is water found in living organisms, as vapor in the atmosphere, and in precipitation as rain and snow. Image Source: Scripps Institution of Oceanography. (2010).
