  1. Journal WP-1 Answer the following questions in complete sentences: • Why is water important? • What are some uses for water? Answer the following questions in complete sentences: • Why is water important? • What are some uses for water?

  2. Earth’s Waters http://www.youtube.com/watch?v=nSENolWbyYQ&feature=player_detailpage

  3. A. Earth: The Water Planet

  4. 1. Importance of Water a. Major Uses 1. Household 2. Agriculture-irrigation a. History • China 3000 BC irrigation by flooding rice paddies • Egypt, 2000 BC-Bucket device invented to raise water • Assyria, 700 BC-Stone aqueduct used by king for plantation • Mexico, 500 AD-raised plots with a canal • USA, 1870 windmills bring water • Israel, 2000-drip irrigation in the desert directly to roots

  5. 3. Industry-usedto make products but can be recycled to cool machinery 4. Transportation-goods and boats 5. Recreation-boating, swimming, etc b. Water is used by living things to grow, reproduce and carry out life processes-like photosynthesis • 66% of the human body is made up of water. • At just 2% dehydration your performance decreases by around 20%. • We should drink at least 1.5 litres of water a day.

  6. c. Groundwateris water that fills cracks and spaces in soil helping to bring nutrients to the soils and organisms in the soil.

  7. d. Water World Two-thirdsof our planet is covered by water. 97%of the water is saltwater (dissolved salt and minerals). *3% is freshwater The majority of freshwater is beyond our reach, locked into polar snow and ice (about 97%). This leaves less than 1% for us to drink.

  8. B. Water Cycle http://www.youtube.com/watch?v=vYBjPE0wekw&feature=player_detailpage

  9. 1. Evaporation • Evaporation occurs when the liquid form of water from bodies of water change into the gaseous form of water

  10. 1a. Evapotranspiration • Evapotranspirationis the water lost to the atmosphere from the ground surface. • The transpiration part is talking about evaporation of water from plant leaves.

  11. 1b. Sublimation • Sublimationis when a solid changes directly into a gas • It is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

  12. 2. Condensation • Condensation is the change of water from its gaseous form (water vapor) into liquid water. • This is crucial because it is responsible for the formation of clouds.

  13. 3. Precipitation • When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation.

  14. 3a. Snowmelt Runoff • Snowmelt runoff is a major component in the water cycle. It “runs off” either side of a dividewhich is a ridge or continuous point of high land into a drainage basin

  15. 3b. Infiltration • Infiltration is when the water enters into the subsurface of soil and rocks. This becomes groundwater. Some soils are permeable-others are impermeable

  16. 3c. Ground-Water Discharge • As part of the water cycle, ground water is a major contributor to flow in many streams and rivers and has a strong influence on river and wetland habitats for plants and animals.

  17. 3d. Ground-Water Storage • Most of the water in the ground comes from precipitation that infiltrates downward from the land surface • Large amounts of water are stored in the ground. In a region called the Aquifer.The upper layer of an aquifer is called a water table

  18. 3e.Bringing Groundwater to the surface Groundwater can be brought to the surface naturally by a spring, an artesian well or a geyser

  19. 4. Water in the “Speres” As water moves through the water cycle, it is “stored” in various ways in the different spheres on Earth

  20. 4a. Water in Atmosphere • Oceans, seas, and other bodies of water contain about 90% of the moisture in the atmosphere. • Other 10%=plants, transpiration. • 3,100 cubic miles of water.

  21. 4b. Water in Hydrosphere • Includes all water on earth. • 1.35 million cubic kilometers of water on earth. • Not a single drop of water can be found anywhere else in the solar system.

  22. 4c. Water in Lithosphere • The solid part of earth. • Is composed of minerals and contains the groundwater.

  23. Water in Biosphere • Is all living organisms. • Covers the top 200 meters of oceans and seas.

  24. Study your notes from the last 2 days. We will have a quiz or journal of some sort WITHOUT your notes! BE READY!!!!!
