  • 5-1: Water on EarthThe graph shows the water used per person in the ten states of the United States with the largest populations.Why is Water Important?

    Body Processes: cellular functionorgan function.

    Habitat:place where organisms live.

  • 5-1 Water on Earth

    These graphs show how much of Earths water is found in different forms.Where is Water Found?

    Salt Water Oceans 97%

    Fresh Water 3%IceRivers and LakesGround Water

  • Water on EarthEarths Major WaterwaysThe map shows Earths oceans and some major freshwater sources.

  • What is The Water Cycle?Water moves between land, living things, bodies of water, and atmosphere.5-1: Water on Earthp 190

  • River Systems

    Tributaries- Streams and smaller rivers that feed into a main river. Pulled by gravity.

    Lesson 2: Surface Waterp 192

  • Watershed- The land area that supplies water to a river system. (Drainage Basin)Surface Waterp194

  • Surface Waterp195Divides- keep watersheds separate by a ridge.valleyPeak

  • What Are Ponds and Lakes? p. 196

  • Lakes form When. 1. Rivers break 2. Glaciers----- (Oxbow lake)

    3. Rift valley ---- cracks in Earths crust

    4. Volcanoes--- old craters 5.Dams ---- Reservoir- a lake that stores water for human use.

  • Eutrophication algae use nutrients (fromDead organisms or waste) and spread forming a layer on surface of water.Lakes change when.p. 198Human RoleFertilizers flow into ponds and lakes.Nutrients in water start the process.

  • Surface WaterAn Endless CycleHow can these processes be diagrammed to show a water cycle?

  • Lesson 3 Exploring the OceanSalinityTotal amount of salt in a solution of water. Changes due to precipitation or evaporation.Effects of SalinityFreezing point of water decreases.Higher density things float easier.

  • Lesson 3 Exploring the OceanTemperature Depends on location and seasonsColder near poles, warmer near equator

    DepthsSurface Warmer, less pressureTransition - in between phaseDeep Cooler, more pressure

  • Exploring the OceanOcean FloorSonar sound navigation. Helps map ocean floor.

    1. Seamount volcanic mountains not above water. Near mid-ocean ridge.2. Trench Long deep valley where ocean floor is sinking.3. Continental Slope From land to water. Ocean floor gets suddenly steep.4. Continental Shelf Gently sloping, shallow area. Transition from land to water. beach5. Abyssal Plain Mud, silt- very bottom, flat, very deep6. Mid Ocean Ridge- chain of mountains. Where new land is forming.

  • 5-4 Currents and ClimateSurface Currents - driven mainly by wind.

    What is a current? -Stream of moving water in oceans. -Moves in a circular motion.Coriolis EffectCurve of wind from poles to equator as earth rotates.

    Northern HemisphereClockwise

    Southern HemisphereCounter-clockwise

  • Surface CurrentsGulf Stream:

    Largest, most powerful

    From Gulf of Mexico to east coast of U.S.

    Effects our weather.

  • Warming Sea TemperatureThe images show what happens to temperature below the surface of the ocean during an El Nio event. Red indicates a warmer sea surface temperature.El NinoEvery 2-7 YearsLARGE amounts of warm water cover an areaCold water cannot move to surface (traps cold water)STRONG weather systemsLa NinaSurface water cooler than usualOpposite of El Nino

  • Deep CurrentsDeep currents near ocean floor

    Caused by: Difference in Density of water

    Carry cold water from poles to equator

    Movement like:Conveyor Beltcold/dense water sinks, warm water pushed upward
