Document Summary

Evaporation (water/liquid into gas in the atmosphere) condensation . Ocean, rivers, lakes, underground, aquifers, clouds, ice/snow. Interception- protects the ground from erosion; vegetation getting in the way (ex. If it"s raining, snowing, hailing, it hits the tree first then it drips down to the ground) Infiltration: water that runs down into the ground. Runoff: when the ground is infiltrated by water, there"s nowhere else for it to go so it runs off. Sublimation: having a solid (ice) and goes to a gas. Building dams: affects vegetation, animals, natural flow in ecosystem. Pumping a lot of water out of aquifers that it causes subsidence; once it"s down, there"s less space to store water in the future. Less water returning into the atmosphere bc it"s not infiltrating, runoff increases. Water goes through sewers and back into the bay; the water is contaminated. Watershed: when all the water in that area drains into the same area (a large body.
