  1. Writing Prompt • Water is essential for life!! Describe the water cycle and how human beings have affected it. At LEAST 5 complete sentences!!!!!

  2. WATER CYCLE

  3. From yesterday….. • Why is the availability of water important to an ecosystem? • Plants need water to live & grow • Animals need water to live • Is water a biotic or abiotic factor?

  4. Information with Numbers • What % of the Earth is covered with water? 71% • How much of the water is freshwater? 3% This includes water stored as ‘ice’…… So there is actually very little usable freshwater

  5. Water falls to Earth…….. -some soaks into the ground becoming GROUNDWATER!!

  6. Groundwater Vocabulary • Permeable-allows water to pass through • Impermeable- does not allow water to pass • Zone of aeration- unsaturated • Zone of saturation – water filled all pores • Water table – top of zone of saturation • Aquifers- groundwater stored in underground layers

  7. Groundwater Zones Draw and label • Zone of aeration • Zone of saturation • Water table • Lake • Well • trees

  8. Groundwater Zones

  9. Aquifers Water that flows through the underground rock, or stored in underground layers.

  10. Warm-Up • 1) Explain the difference between the permeable & impermeable rock layers discussed yesterday. • 2) Compare and Contrast the Zone of Aeration and the Zone of Saturation.

  11. Water falls to Earth…….. -gravity causes some to flow downhill as SURFACE WATER!!!! -this is called runoff

  12. SURFACE WATER • Water that has NOT soaked into the ground • As it moves downhill, • Forms water in streams & rivers

  13. Drainage Basin- area that is drained by a river & all the streams that empty into it • Also called a watershed • Can be identified by studying a map showing rivers & tributaries

  14. Surface-water-Runoff and Drainage • Drainage Basin ( Watershed) - area drained by the rivers and all the streams that empty into it • Divide – high ground between two drainage basins

  15. SC River Map • Color & Label the 4 major Drainage Basins in the state of South Carolina. • PeeDee - Green • Santee - Red • ACE - Blue • Savannah – Yellow • List the rivers located in each Drainage Basin.

  16. 4 Major SC Drainage Basins

  17. DAM • Divide- high ground between 2 drainage basins • Man-made divides with 2 purposes • Recreation and Power

  18. Importance (Ecosystem) • Oceans/Rivers/Streams/Creeks (food?) • Erosion – wearing away of sediments or rocks • Flowing water removes, carries, and deposits sediments. • Meander – bending and winding of a river or stream • Deltas: Santee Delta & Mississippi Delta • Where a river ends its journey & empties into a lake or ocean

  19. Importance (Human Activities) • Human beings are dependent upon water for survival. • Produce Hydroelectric power • Offer Recreation • Contains sources of food

  20. Classwork- 10/10/12 • Divide your paper into 3 columns • Label the columns.. • Groundwater • Surface Water • Importance of Water • Cut out each of the squares from the worksheet & place each one under the correct heading • Show me your work & then glue the squares down once I have checked your arrangement

  21. On your index card……. • Draw & Label a diagram of the groundwater zones. • Be sure to include ALL of the following • Lake • Well • Zone of aeration • Zone of saturation • Water table • Impermeable rock layer • Aquifer

  22. HOMEWORK! • READ p. 459-460 in your book –and- • Explain, in complete sentences, 6 ways in which surface water, ocean water, & groundwater can become polluted and what each of these ways means for the ecosystem.

  23. Warm-Up • Compare groundwater to surface water.

  24. Summarize how the location and movement of water on Earth’s surface are important.

  25. True or False • Human beings are dependent upon water for survival. • Hydroelectric plants are located near rivers. • Behind dams, people are not allowed to have recreation. • Earth is 71% water with 3% freshwater. • “ Usable “ freshwater includes ice.

  26. Exemplify ways that humans use water.

  27. Create a diagram of groundwater zones and place your home in a location. Explain the placement of your home.

  28. Groundwater Zones and Layers
