Presentation Transcript

  1. Weather and Water

  2. Evaporation • The process in which liquid water becomes water vapor

  3. Humidity • The water vapor in the air

  4. Relative Humidity • The amount of water vapor in the air compared to the amount of water vapor needed to saturate the air at a give temperature; expressed as a percentage

  5. Condensation • The process in which water vapor becomes liquid water

  6. Condensation nucleus • A small particle on which water vapor condenses

  7. Cloud • A visible accumulation of water on condensation nuclei, either as liquid or ice, usually high in the air

  8. Precipitation • Any form of water that falls from the sky/clouds

  9. Rain • Liquid form of precipitation. It stays liquid from beginning to end.

  10. Sleet • Precipitation that starts out as a liquid but freezes on the way down from the cloud to the Earth.

  11. Hail • Precipitation in the form of balls of ice. Freezes in the clouds

  12. Freezing Rain • Liquid precipitation that freezes on contact once it has landed on surfaces on Earth (Cars, trees, grass, concrete)

  14. Question 1 • What is the process in which water vapor becomes liquid water called? • Evaporation • Precipitation • Condensation • None of these are correct

  15. Question 2 • What is the process in which liquid water becomes water vapor called? • Evaporation • Precipitation • Condensation • None of these are correct

  16. Question 3 • What does water vapor attach too to become liquid water again • Cloud • Condensation Nucleus (Nuclei) • Precipitation • None of these are correct

  17. Question 4 • What is any form of water that falls from the sky/cloud called? • Evaporation • Precipitation • Condensation • None of these are correct

  18. Question 5 • What falls from the sky as water and freezes before it reaches Earth? • Hail • Rain • Sleet • Freezing Rain

  20. Question 1 • What is the process in which water vapor becomes liquid water called? • Evaporation • Precipitation • Condensation • None of these are correct

  21. Question 2 • What is the process in which liquid water becomes water vapor called? • Evaporation • Precipitation • Condensation • None of these are correct

  22. Question 3 • What does water vapor attach to to become liquid water again • Cloud • Condensation Nucleus (Nuclei) • Precipitation • None of these are correct

  23. Question 4 • What is any form of water that falls from the sky/cloud called? • Evaporation • Precipitation • Condensation • None of these are correct

  24. Question 5 • What falls from the sky as water and freezes before it reaches Earth? • Hail • Rain • Sleet • Freezing Rain

  25. Run Off • When rain lands or snow melts and the water flows, it carries with it anything it touches.For example: • -Oil from shingles on the house -Fertilizers -Dirt/sand

  26. Photosynthesis • A process used by plants to convert water, carbon dioxide, and sunlight into carbohydrates and oxygen.

  27. Transpiration • The release of water from plants as a product of photosynthesis.

  28. Temperature • A measure of kinetic energy of the molecules of a material or substance.

  29. Thermometer • An instrument to measure temperature

  30. Dew Point • The temperature at which a volume of air is saturated with water vapor; condensation occurs when the temperature drops below the dew point.

  31. Dew • Water that condenses on surfaces when the temperature drops below the dew point.

  32. Frost • Frozen dew. This occurs when the dew point is below 0oC (32oF)

  33. Water Cycle Project

  34. Criteria • In any means you deem school appropriate, • i.e.: Song, Comic, Video, Rap, creative story, etc. NOT AN ESSAY!!! • tell the story of a drop of water as it goes through the water cycle. The story must start and end in a toilet. The story must include:

  35. Evaporation • Condensation • Precipitation • Condensation Nucleus • Run Off • Photosynthesis • Transpiration • At least an area of 500 miles • Dew • Dew Point • Frost • Temperature

  37. Water Cycle Quiz April 24, 2013

  38. Question 1 • What is the process in which water vapor becomes liquid water called? • Evaporation • Precipitation • Condensation • None of these are correct

  39. Question 2 • What is the process in which liquid water becomes water vapor called? • Evaporation • Precipitation • Condensation • None of these are correct

  40. Question 3 • What does water vapor attach too to become liquid water again • Cloud • Condensation Nucleus (Nuclei) • Precipitation • None of these are correct

  41. Question 4 • What is any form of water that falls from the sky/cloud called? • Evaporation • Precipitation • Condensation • None of these are correct

  42. Question 5 • What falls from the sky as water and freezes before it reaches Earth? • Hail • Rain • Sleet • Freezing Rain

  43. Question 6 • What happens when the temperature falls below the dew point? The air absorbs more water vapor and it condenses into clouds The air absorbs more water vapor and it condenses onto any surface The air releases water vapor and it condenses into clouds The air releases water vapor and it condenses onto any surface.

  44. Question 7 Which statement is true? • The higher the temperature the less water vapor the air can hold before it is saturated • The lower the temperature the less water vapor the air can hold before it is saturated • Temperature does not affect how much water vapor the air can hold

  45. Question 8 • What is relative humidity? The amount of water vapor needed to saturate the air half way The amount of water vapor in the air compared to how much is needed to saturate the air The amount of condensation on surfaces compared to the amount of water vapor in the air.

  46. Question 9 • What is true about convection? Air rises from an area of extreme heating until it cools then falls back to Earth. Air rises from an area of extreme cooling until it heats up and then falls back to Earth Convection is a process that is not understood by scientists.
