Transcript

  • 1. Physical ScienceModule 5 The Hydrosphere
  • 2. Hydrosphere What is the Hydrosphere? The sum of all the water on the planet Life cannot exist on any other planet but can on earth because of what? Water
  • 3. Water Water is only liquid in what range? Above 32 degrees Fahrenheit and below 212 Fahrenheit What two factors control the temperature of our planet? The sun and the atmosphere
  • 4. Facts to Memorize The vast majority of the earth’s water supply is contained in the oceans as saltwater The vast majority of earth’s freshwater supply is stored in icebergs and glaciers The largest source of liquid freshwater is groundwater
  • 5. The Hydrologic Cycle What is the Hydrologic Cycle? The process by which water is continuously exchanged between earth’s various water sources
  • 6. Hydrologic Cycle Water gets into the atmosphere predominately by Evaporation and Transpiration Transpiration = Evaporation of water from plants – water evaporating off its leaves Evaporation takes water out of the oceans, lakes, rivers, and streams, while transpiration takes water from the soil
  • 7. Evaporation Evaporation: the change of state in a substance from a liquid to a gas. For evaporation to take place, energy is required. The energy can come from any source: the sun, the atmosphere, the earth, or objects on the earth such as humans.
  • 8. Transpiration Transpiration is the evaporation of water from plants through stomata. Stomata are small openings found on the underside of leaves that are connected to vascular plant tissues. In most plants, transpiration is a passive process largely controlled by the humidity of the atmosphere and the moisture content of the soil. Transpiration depletes soil moisture
  • 9. Transpiration
  • 10. Soil Moisture Soil moisture can also be depleted when it soaks down into the groundwater sources and feeds into lakes, rivers, and streams by the process known as what? Groundwater Flow
  • 11.  Clouds form by what process? Condensation The process by which a gas turns into a liquid
  • 12. Condensation
  • 13. Other Condensation
  • 14. Precipitation What is precipitation? Water falling from the atmosphere as rain, snow, sleet, or hail What is surface runoff? When precipitation falls on land and replenishes soil moisture OR it can run along the surface of the land into an ocean, lake, river, or stream
  • 15. Let’s Review Precipitation can happen in what ways? What are the two ways water can return to the sky? How are clouds formed? What is soil moisture? What is surface runoff?
  • 16. Experiment 5.1 Get out your Lab Report and a pencil Need two volunteers
