  2. hydrologic cycle
    the process by which water is continuosly exchanged between earths many water sources
  3. transpiration
    evaporation of water in plants
  4. condensation
    the process by which goes turns into liquid
  5. precipitation
    water falling from the atmosphere as rain sleet and snow
  6. distillation
    evaporation and condensation of a mixture to seperate out the mixtures individual components
  7. residence time
    the average time a given particle will stay in a given system
  8. salinity
    a mesure of the mass of dissolved salt in a given mass of water
  9. firn
    a dense icy pack of old snow
  10. water table
    the line between the water saturated soil and the unsaturated soil
  11. percolation
    the process by which water moves downward in the soil toward the water table
  12. adiabatic cooling
    the cooling of gas that happens when the gas expands with no way of getting more energy
  13. cloud condensation nuceli
    small airborne particles upon which water vapor codenses to form clouds
  14. what kind of water makes up the majority of earths water supply
  15. what is the largest source of freshwater on the planet
    in icebergs and glaciers
  16. what is the largest source of liquid freashwater on the planet
  17. in the hydrologic cycle name ways water can enter the atmosphere
    evaporation and transpiration
  18. when a raindrop hits the ground name 3 ways it can end up in a river
    surface runoff, groundwater flow , transpiration
  19. what process in the hydrologic cycle puts soil moisture into the atmosphere
  20. in which body of water would the residence time be shorter: a qick moving river or a lake that has no outlets
    a quick moving river
  21. what must a lake have in order for it to be a freshwater lake
    low salt concentration
  22. why is salinity of the oceans evidence that the earth is not billions of years old
    if the earth was billions of years old the oceans would be way saltier
  23. if you melted sea ice would it taste like freshwater or saltwater
    salt water: because when water freezes water sourounds a packet of ice
  24. where do icebergs come from
  25. where do glaciers come from
    it falls off snowy mountians
  26. what is the term for the process by which  a portion of a glacier breaks off and falls into the water
  27. the captian of a ship sees an iceberg and steers clear of it . why is the captian still worried of a collision
    90% of  the iceberg is  underwater
  28. suppose you studied 2 areas of land close to one another . in the first there are alot of trees . in the second there are hardly any trees. which one has a deeper water table
    the first one
  29. if no energy is added to air what happpens to the temperature when the air expands
    it cools : when there is energy and the air expands then it warms
  30. will fog be thicker in a smokey area or a non smokey area
    smokey area
  31. what kind of cooling is responsible for most cloud formation
    adiabatic cooling
  32. a bright student notes that with a few modifications a refrigerator can become a hot bot keeping thing warm instead of cold
    if you add energy to the air in a refriderater the air will become hot
  33. what kind of water pollution is the hardest to track beck to its source
    ground water  pollution
