Bodies of water

  1. 1. BODIES OF WATER
  2. 2. Water Cycle <ul><li>The continuous movement of water from the earth to the atmosphere and back to the earth. </li></ul><ul><li>The sun provides the energy for the water cycle, also known as the hydrologic cycle. </li></ul><ul><li>The water cycle occurs in four overlapping spheres. </li></ul>
  3. 3. Water Cycle
  4. 4. Hydrosphere <ul><li>Water moves from the earth to the atmosphere through the processes of evaporation and transpiration. </li></ul><ul><li>Evaporation is the transformation of water from its liquid form to its gaseous form as a result of coming in contact with heat or the air. </li></ul><ul><li>Transpiration is the process of plants releasing water through their leaves. </li></ul>
  5. 5. Physical and Chemical Makeup of Water <ul><li>Water, in its purest form, is tasteless, odorless, and colorless. </li></ul><ul><li>It is a chemical compound made up of two atoms of hydrogen and one atom of oxygen. </li></ul><ul><li>Its chemical symbol is H 2 O. </li></ul>
  6. 6. Physical States of Water <ul><li>Solid form of water is called ice. </li></ul><ul><li>Water freezes at 32 º F or 0 º C. </li></ul><ul><li>Gaseous form of water is called water vapor or steam. </li></ul><ul><li>When water boils it turns into water vapor or steam. Water boils at 212°F or 100°C. </li></ul><ul><li>In between the gaseous and solid form, water is in its liquid form. </li></ul>
  7. 7. Chemical Make-up of Water <ul><li>Water that contains salt is called saline water. </li></ul><ul><ul><li>Sodium chloride, potassium, and magnesium can raise the level of salts in the water. </li></ul></ul><ul><ul><li>The amount of salt in the water will determine its usefulness. </li></ul></ul><ul><ul><li>Water that is too high in salt cannot be used for drinking or irrigation. </li></ul></ul>
  8. 8. Categories of Saline Water <ul><li>Freshwater </li></ul><ul><li>Saltwater </li></ul><ul><li>Brackish water </li></ul>
  9. 9. Freshwater <ul><li>Water with less than 3.0 parts per thousand (ppt) of salt. </li></ul><ul><li>Most commonly found in drilled wells, streams, and lakes. </li></ul><ul><li>Only 3 percent of the water on the earth is considered freshwater, of this 3 percent only 1 percent is available for use. </li></ul>
  10. 10. Saltwater <ul><li>Water with 16.5 ppt or more of salt. </li></ul><ul><li>Some ocean and sea water is as high as 33 to 37 ppt. </li></ul><ul><li>Saltwater makes up about 97 percent of the earth’s water. </li></ul>
  11. 11. Brackish Water <ul><li>A mixture of saltwater and freshwater. </li></ul><ul><li>Brackish water is found where freshwater flows into the ocean or other bodies of saltwater. </li></ul><ul><li>An estuary is the area where a freshwater stream flows into the ocean or a saltwater lake. </li></ul>
  12. 12. Usable Water <ul><li>Two main ways that salt water and contaminated water can be turned into usable water: distillation and desalination. </li></ul>
  13. 13. Usable Water <ul><li>Distillation is the boiling of water and collection of its vapor. </li></ul><ul><li>The vapor then turns into liquid when cooled. </li></ul><ul><li>The liquid is pure at this point. </li></ul>
  14. 14. Usable Water <ul><li>Desalination is the removal of salt from water. </li></ul><ul><li>It involves the process of distillation but is not economical on a large scale. </li></ul>
  15. 15. Flowing Bodies of Water <ul><li>One of the most important parts of the water cycle is the stream. </li></ul><ul><li>Streams are flowing bodies of water that are useful resources for irrigation, factories, and local water systems. </li></ul>
  16. 16. Food Web in Streams <ul><li>Most streams are freshwater and they can flow through a natural or man-made channel. </li></ul>
  17. 17. Types of Streams <ul><li>Stream type is determined by the volume and velocity of the movement of water, or stream flow. </li></ul><ul><li>The four types of streams are rivers, creeks, brooks, and canals. </li></ul>
  18. 18. Cross Section of a Stream <ul><li>The rate of flow in a stream is called a current. </li></ul>
  19. 19. River <ul><li>The largest stream. </li></ul><ul><li>Have high streamflows. </li></ul>
  20. 20. Creek <ul><li>A stream that is smaller than a river. </li></ul><ul><li>Often flow into rivers, lakes, and oceans. </li></ul>
  21. 21. Brook <ul><li>A small stream. </li></ul><ul><li>Often flow into creeks, rivers, lakes, and oceans. </li></ul>
  22. 22. Canal <ul><li>An artificial waterway built for transportation, to relieve flooding, or to divert the flow of water. </li></ul>
  23. 23. Non-Flowing Bodies <ul><li>Bodies of water that do not flow still have water movement. </li></ul><ul><li>The internal movement is caused by temperature changes and salinity. </li></ul>
  24. 24. Types of Non-Flowing Bodies <ul><li>Seven types of non-flowing bodies of water are oceans, lakes, ponds, reservoirs, sloughs, marshes, and estuaries. </li></ul><ul><li>As in flowing streams, non-flowing bodies of water may contain a variety of ecosystems . </li></ul>
  25. 25. Oceans <ul><li>Large bodies of saltwater. </li></ul><ul><li>Cover almost 75 percent of the surface of the earth. </li></ul>
  26. 26. Lakes <ul><li>Bodies of freshwater that are surrounded by land. </li></ul><ul><li>Vary in size, some are natural and others are man-made. </li></ul>
  27. 27. Ponds <ul><li>Non-flowing bodies of water that are smaller than lakes. </li></ul><ul><li>Commonly manmade and used as a source of recreation or for use by livestock. </li></ul>
  28. 28. Reservoirs <ul><li>Large bodies of stored water. </li></ul><ul><li>Commonly used to generate electric power. </li></ul>
  29. 29. Sloughs <ul><li>Thick, muddy areas of shallow water. </li></ul>
  30. 30. Marshes <ul><li>Areas of land covered with shallow water and plants such as cattails. </li></ul><ul><li>Do not contain trees and are similar in nature to sloughs. </li></ul>
  31. 31. Estuaries <ul><li>Areas where freshwater streams flow into the ocean or a saltwater lake. </li></ul>estuary
  32. 32. Review / Summary <ul><li>Describe the water cycle. </li></ul><ul><li>Describe the physical and chemical makeup of water. </li></ul><ul><li>Identify bodies of flowing water. </li></ul><ul><li>Identify bodies of non-flowing water. </li></ul>
