The Water Cycle Final Product

  1. 1. The Water Cycle
  2. 2. <ul><li>Describes the movement of water on, in, and above the earth </li></ul><ul><li>Water is always changing and moving from one place to another </li></ul><ul><li>This cycle is made up of a few main parts: </li></ul><ul><li>Precipitation </li></ul><ul><li>Infiltration </li></ul><ul><li>Runoff </li></ul><ul><li>Transpiration </li></ul><ul><li>Evaporation </li></ul><ul><li>Water Vapor </li></ul><ul><li>Condensation </li></ul><ul><li>Collection </li></ul>
  3. 3. <ul><li>The repeating change of water on the Earth creates a cycle </li></ul><ul><li>As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor) </li></ul><ul><li>Ice can change to become water or water vapor </li></ul><ul><li>Water can change to become ice or water vapor </li></ul><ul><li>Water vapor can change to become ice or water. </li></ul>
  4. 4. <ul><li>Happens when the temperature and the atmospheric pressure are right </li></ul><ul><li>The small droplets of water in clouds form larger droplets and precipitation occurs. The raindrops fall to earth. </li></ul><ul><li>Occurs when so much water has condensed that the air cannot hold it anymore </li></ul><ul><li>The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow </li></ul><ul><li>Click the speaker below to hear rain falling </li></ul>
  5. 5. <ul><li>Rain: Sleet: </li></ul><ul><li>Snow: Hail: </li></ul>
  6. 6. <ul><li>Important process where </li></ul><ul><li>rain water soaks into the </li></ul><ul><li>ground, through the soil and underlying rock layers </li></ul><ul><li>The flow of water from the </li></ul><ul><li>ground surface into the ground </li></ul><ul><li>Once infiltrated, the water </li></ul><ul><li>becomes soil moisture or </li></ul><ul><li>groundwater </li></ul>
  7. 7. <ul><li>Movement of water underground is called groundwater flow </li></ul><ul><li>Groundwater slowly moves through the spaces and cracks between the soil particles on its journey to lower elevations </li></ul>
  8. 8. <ul><li>The movement of land water to the oceans, mainly in the form of rivers, lakes, and streams </li></ul><ul><li>Consists of precipitation that neither evaporates, transpires nor penetrates the surface to become groundwater </li></ul><ul><li>Excess runoff can lead to flooding, which occurs when there is too much precipitation </li></ul>
  9. 9. <ul><li>Process that happens through plants </li></ul><ul><li>As plants absorb water from the soil, the water moves from the roots through the stems to the leaves </li></ul><ul><li>Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. </li></ul>
  10. 10. <ul><li>The process where a liquid, in this case water, changes from its liquid state to a gaseous state. </li></ul><ul><li>The sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. </li></ul><ul><li>The water vapor or steam then leaves the river, lake, or ocean and goes into the air. </li></ul>
  11. 11. <ul><li>Water in its gaseous state-instead of liquid or solid (ice) </li></ul><ul><li>Totally invisible </li></ul><ul><li>Extremely important to the weather and climate </li></ul><ul><ul><li>Without out it, there would be no clouds or rain or snow </li></ul></ul><ul><ul><li>All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow </li></ul></ul>
  12. 12. <ul><li>Formation of liquid drops from water vapor </li></ul><ul><li>Occurs when a parcel of rising air expands and cools </li></ul><ul><li>Responsible for the formation of clouds </li></ul><ul><ul><li>These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle </li></ul></ul>
  13. 13. <ul><li>When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land </li></ul><ul><li>When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink. </li></ul><ul><li>It may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again. </li></ul>
  14. 14. <ul><li>Adding or subtracting heat makes the cycle work. </li></ul><ul><li>If heat is added to ice, it melts. If heat is added to water, it evaporates. </li></ul><ul><li>Evaporation turns liquid water into a gas called water vapor. </li></ul><ul><li>If heat is taken away from water vapor, it condenses. </li></ul><ul><li>Condensation turns water vapor into a liquid. </li></ul><ul><li>If heat is taken away from liquid water, it freezes to become ice. </li></ul>
  15. 15. <ul><li>Humans use water for drinking, respiration, perspiration, and elimination of wastes are all part of this cycle </li></ul><ul><li>Large amounts of water are needed for most economic activities: agriculture and mining, food processing, manufacturing </li></ul><ul><li>Lakes and rivers provide towns and cities with a means of discharging wastes </li></ul>
  16. 16. <ul><li>Generation of electricity from thermal power plants </li></ul><ul><li>Waterways provide transportation </li></ul><ul><li>Recreational activities </li></ul><ul><li>Some people view the rivers and large lakes of this country as a part of their own identity </li></ul><ul><li>AND MUCH MORE!!! </li></ul>

  19. 19. <ul><li>The water cycle is called the hydrologic cycle. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. </li></ul><ul><li>Water vapor condenses into millions of tiny droplets that form clouds. </li></ul><ul><li>Clouds lose their water as rain or snow, which is called precipitation. </li></ul><ul><li>Precipitation is either absorbed into the ground or runs off into rivers. </li></ul><ul><li>Water that was absorbed into the ground is taken up by plants. </li></ul><ul><li>Plants lose water from their surfaces as vapor back into the atmosphere. </li></ul><ul><li>Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere. </li></ul><ul><li>The cycle continues. </li></ul>
