  13. 27. Meteorologists use ___________ to represent different kinds of weather fronts
Down
  1. 1. a type of weather front where an air mass gets separated from the ground by a fast-moving cold air mass, resulting in heavy rain
  2. 2. a type of weather front where a cold air mass and a warm air mass meet, but neither pushes the other out of the way
  3. 3. the circulation of air due to heating and cooling of molecules
  4. 6. the process of water vapor turning into liquid water
  5. 7. a type of weather front where cold air masses overtake warm air masses
  6. 9. the process by which solids form
  7. 10. the layer of gases that surrounds Earth or another planet.
  8. 11. a type of weather front where warm air masses overtake cold air masses
  9. 12. a thick, dense cloud located near the ground
  10. 14. a large, tall, and dense cloud that often produces heavy rain and thunderstorms
  11. 15. Winds are caused due to ____________ __________ of the Earth
  12. 16. winds that blow mostly in one direction, moving air masses
  13. 18. a glowing light in Earth’s atmosphere, usually near the North Pole, caused by the collisions of charged particles with atoms in Earth’s atmosphere.
  14. 19. water beneath the surface of the ground
  15. 22. the process by which water changes from a liquid to a gas or vapor
