  1. EOG Review Water On Earth (Goals 3.01-3.03)

  2. Goal 3.01 The Properties of Water

  3. ___1. Polarity ___2. Cohesion ___3. Surface tension ___4. Adhesion ___5. Capillary action ___6. Universal solvent ___7. High specific heat ___8. Density Water molecules cling together Requiring a lot of heat to cause an increase in temperature Water molecules cling to other substances Electrically charged Tightness across the surface of water Able to dissolve many substances Determines if an object sinks or floats Allows water to travel along other substances Properties of Water

  4. Polarity • Formula for Water: _____ • Hydrogen atoms – _______ charge • Oxygen atom – _______charge • Opposites ________

  5. Cohesion & Adhesion Cohesion/Surface tension: Adhesion/Capillary action:

  6. Universal Solvent In the picture of someone making Kool-Aid, determine each of the following… • Solute - • Solvent - • Solution - Why is water considered to be the universal solvent?

  7. High Specific Heat Specific heatis the amount of energy needed to raise the temperature of 1 kg of a substance by 1oC. The specific heat of water is very high. Therefore, water takes a ________time to heat up or cool down. Remember our “trip” to the beach…. • Which gets hot faster – sand or water? • Which cools down faster – sand or water?

  8. Density Density = ??? / ??? How would you find mass? How would you find volume of a liquid? …of a solid? Density of water = 1 g/mL More than 1 g/mL… _____ Less than 1 g/mL… _____ Remember…liquid layers

  9. Goal 3.02 Structure of the Hydrosphere

  10. Water on Earth

  11. Underground Water

  12. Water Underground An __________is a rock layer that stores water and allows water to flow through it.

  13. Wetlands Wetlands are land areas that remain wet for all or part of the year. Benefits:

  14. Watersheds (River Basins) • A ____________is an area of land where precipitation collects and then drains into a single collection place, lake an ocean or lake. • Allows water to ________from higher to lower elevations

  15. Major Watersheds of the US

  16. Goal 3.03 Earth’s Oceans

  17. Ocean Exploration

  18. und vigationanging

  19. Deep Ocean Technology Remote Operated Vehicles (ROVs) Piloted Vessels Jason ALVIN, Deep Flight

  20. - Exploring the Ocean Features of the Ocean Floor If you could travel along the ocean floor, you would see the continental shelf, the continental slope, the abyssal plain, and the mid-ocean ridge.

  21. Ocean Zones & Conditions Ocean zones include the: • Intertidal zone – • Neritic zone – • Oceanic zone –

  22. Life in the Ocean Scientists classify marine organisms according to where they live and how they move: • Plankton - • Nekton - • Benthos -

  23. What is an Estuary? • Estuaries are coastal inlets or bays where fresh water from rivers _______ with the salty ocean water. • Water that is partly salty and partly fresh is called brackish. • Coastal wetlands are found in and around estuaries.

  24. Upwelling Upwelling is the movement of cold water upward from the deep ocean that is caused by wind. • Upwelling brings up _________________, ________, and other _________from the deeper layers of the water. • Without this motion, the surface waters of the open ocean would be _____________in nutrients.

  25. Hydrothermal Vents • Hydrothermal vents are cracks in the ocean crust that release mineral-rich water that has been heated by Earth’s interior. • _______(extremophiles) near the vents make food using chemicals in the vent water. • Tubeworms and clams use this bacteria for food.

  26. Living Resources: Nonliving Resources: Ocean Resources
