Hydorologic cycle

  1. 1. The Hydrologic Cycle By: Kayleigh Wiehaus & Amelia Young
  2. 2. Brief DescriptionThe hydrologic cycle begins with water evaporating from the oceans surface.Moist air is then lifted up and cools and then condenses to form clouds. Themoisture is transported all around the globe until it comes back to the surface asprecipitation. The water then reaches the earths surface and either evaporatesback or becomes groundwater. If if becomes groundwater then it goes into oceans,rivers, etc. or it goes back into the atmosphere through the transpiration process.The leftover water on the earth is known as runoff, which then empties into lakesrivers, oceans, etc. where the cycle starts again.

  5. 5. EvaporationThis is when the sun heats water in rivers, lakes, oceans, etc.and turns it into vapor. The vapor then rises into the air,which then leads to the formation of clouds.
  6. 6. CondensationWater vapor changes from a vapor to, usually, a liquid. Thevapor condenses to small particles forming dew, clouds, orfog. Condensation is brought about by the air cooling to itssaturation point.
  7. 7. PrecipitationOccurs when a lot of water condensed so much that the aircannot hold it any longer. The clouds then get extremelyheavy and water falls from them in the form of rain, sleet,snow, or hail.
  8. 8. TranspirationThe biological process that mostly occurs during the daytime.The water inside plants is transferred from the plant to theatmosphere as vapor. Plants transpire to cool their leavesexposed to sun and to move nutrients to the upper part of theplant.
  9. 9. Runoff This occurs when water does not forego the transpiration andevaporation process, and is leftover on the earth which thenempties into lakes, rivers or oceans. After this, the cycle thenrepeats itself.
  10. 10. SinksAquifer: Water is stored in an aquifer which is a body of saturated rock throughwhich water can move easily. They must be both permeable and porous.All major bodies of water such as oceans, lakes, rivers, streams, etc.
  11. 11. SignificanceWater is one of the most important necessities of life, we cannot live withoutwater. There is approximately 1 percent of fresh water on earth, so it is veryhelpful that the water we use and its continuous replacement is a result of thehydrologic cycle. The cycling of all other elements is dependent upon water.
  12. 12. Ways humans affect it We are becoming very aware of the impacts on nature, however it is unfortunate that many of the things we have done are causing a negative affect and can be irreversible. Such as hydroelectricity, irrigation, deforestation and the greenhouse effect, vehicles and even animal farming.
