Across
  1. 4. the change from gas to liquid such as water vapor changing to rain
  2. 7. global winds that flow toward the poles from the west or east between 30° and 60° north or south latitude
  3. 10. weather front that develops when cold air moves up under warm air and causes colder temperatures; sometimes thunderstorms
  4. 11. the middle and coldest layer of the atmosphere
  5. 17. weather tool that measures wind speed
  6. 19. local winds that are created by the uneven heating of the land and ocean; these will reverse from day to night
  7. 20. a group of the same species that live together
  8. 22. all of the living organisms in an ecosystem
  9. 23. biome made of trees called conifers that are shaped like needles
  10. 25. organisms that produce their energy from the sun
  11. 28. a symbiotic relationship in which one organism benefits and the other organism is not affected
  12. 29. the lowest and densest layer of the atmosphere where all weather occurs
  13. 31. organisms that that get their energy from breaking down dead materials
  14. 32. diagram that shows the loss of energy in an ecosystem beginning with the producers and ending with the top predator
  15. 33. a symbiotic relationship in which one organism benefits and the other organism is harmed
  16. 34. type of cloud that forms at high altitudes and appear thin and wispy; they may contain ice crystals
  17. 35. the variable in an experiment that causes something to change
  18. 36. weather front in which a cold air mass meets a warm air mass meet and remain in place pushing against each other without moving for several days
  19. 37. global winds in both hemispheres that blow from 30° latitude to almost the equator
  20. 38. global winds that are formed as cold, sinking air moves from the poles to 60° north or 60°south latitude
  21. 40. trade winds in both hemispheres that meet around the equator where there is very little wind
  22. 42. weather tool that measures temperature
  23. 44. cloud that may produce a strong thunderstorm
  24. 45. the measure of the force of the atmosphere pressing down on earth's surface
  25. 46. organisms that eat other organisms for energy
Down
  1. 1. biome that has very cold temperatures and where the ground is always partially frozen
  2. 2. all of the nonliving parts in an ecosystem
  3. 3. weather front that forms when a warm air mass is caught between two cold air masses
  4. 5. a symbiotic relationship in which both organisms benefit
  5. 6. all of the abiotic and biotic elements of a specific area
  6. 8. the layer of the atmosphere that slowly blends with outer space where there is no atmosphere
  7. 9. weather front where warm air slowly moves over cold air, temperatures will warm and drizzly rain may occur
  8. 12. the transfer of thermal energy in a circular motion through a liquid or gas
  9. 13. the warming of the earth due to the gases in earth's atmosphere
  10. 14. type of cloud that layers the sky like a blanket and often blocks out the sunlight
  11. 15. web diagram that shows the feeding relationships between organisms in an ecosystem
  12. 16. the variable in an experiment that may change due to the introduction of something new
  13. 18. the mixture of gases that surrounds earth and keeps the planet warm
  14. 21. the "hottest" layer of the atmosphere
  15. 22. weather tool that measures air pressure
  16. 24. a possible explanation or educated guess about the outcome of an experiment
  17. 26. biome that has the most diversity of organisms on the planet
  18. 27. the apparent curving of the path of global winds due to earth's rotation
  19. 30. biome that is mostly covered by grasses and home to grazing animals that travel in large herds
  20. 31. information gathered from observing what occurs in an experiment
  21. 39. the layer of the atmosphere in which most of the ozone can be found
  22. 41. biome that is very dry and hot where little rain fall will happen
  23. 43. type of cloud that are large, white, and puffy usually seen during fair weather
  24. 44. all of the populations of species that live in the same area
