  1. Unit 12 Water By Jared Loftin, Justin Newberry, Josh Cobos, Sam Walker, and Ozzy Garcia

  2. Water Management • Oceanography- Knowledge of science to study all aspects of the worlds ocean. Water management is the activity of planning, developing, distributing, managing, and optimum use of water resources under defined water. • It is recognized that water problems cannot be solved by quick technical solutions, solutions to water problems require the consideration of cultural, educational, communication and scientific aspects. Given the increasing political recognition of the importance of water, it is in the area of sustainable freshwater management that a major contribution to avoid/solve water-related problems, including future conflicts, can be found.

  3. Water Management • Rivulets- A very small stream • SWM attempts to deal with water in a holistic fashion, taking into account the various sectors affecting water use, including political, economic, social, technological and environmental considerations.

  4. Water Management • The Mar del Plata Water Conference was hosted by the UN in 1977. • SWM has been high on the international agenda

  5. Scene 4 • Water Table – The upper level of the saturated zone of groundwater. • How does water pollution affect marine life?It affects it because all the animals will die because of all the pollution also because of what we humans like litter or oil gets thrown into the ocean and kills the fish and other animals in the ocean.

  6. Scene 5 • Water Cycle – Cycle at which water goes through. • Water holds how much life on Earth? It holds 80% of all life on Earth. • How much water covers the earth?About 70% of are world is covered in water.

  7. Scene 6 • How many different corals are there?There are about 700 different kinds of corals underwater around the world.

  8. Scene 7 • Most of the earth is covered by rock and water. But mostly just water. 71% to be exact is just water. 97% of the 71% is salt water and 2.2% of the 71% is water has frozen over time, But only 1% of it is actually drink able.

  9. Scene 8 The Hydrosphere is one of the biggest factors in human survival. Without it we would not be able to live, even though we pollute the little bit that is actually drinkable. Humans effect the hydrosphere by agriculture, irrigation, and gardening.

  10. Scene 9 • The industrialization of the hydrosphere widely varies. From public water systems, using irrigation systems, to produce crops and having water plants to produce energy. Air pollution, public dumping, and animals all effectively pollute the hydrosphere. • Evapotranspiration- is the sum of evaporation and plant transpiration from the earth.

  11. Scene 10 • Sea floor sediments- Made up of terrigenous, biogenous, and hydrogenous sediment.

  12. Scene 11 • Continental margins- The Continental shelf and ridge.

  13. Scene 12 • Preservation- The maintaining of water quality. (ex. Reducing pollution from runoff, using filtration) • Conservation- The wise use of water. (ex). Watering on the right dates and only using water when needed EPA is responsible for the conservation and preservation of water 70% of the worlds fresh water use comes from crop irrigation

  14. Effects on Humans • Earthquakes effect humans in a variety of ways. One way is that the buildings will collapse depending on the magnitude of the earthquake, determined by the Richter scale which is the main cause for death. Other indirect ways include not having food or freshwater. It also causes billions of dollars worth in damage.

  15. Effects on Humans • A tsunami can be a by product of an earthquake. Generally above a 7.5 a tsunami is very likely. They are long waves caused by a disturbance in the ocean such as a submarine landslide or a meteorite. Tsunamis can travel thousands of miles up to 800km per hour. Can also have very dangerous surges which can completely cover a building.

  16. Effects on Humans • Acidification - is the increasing acidity of the ocean. • A volcano can be very hazardous to humans. Besides the fact that lava can reach degrees up to 1250 degrees Celsius. The lava flows can also travel up to 200km per hour so you cant outrun it. They also produce toxic fumes which can choke and kill you. Volcanoes also kill crops which can cause food shortages which may lead to a famine in third world countries.
