Across
- 1. Composed of water droplets and, if high enough are ice crystals. Looks like puffy cotton balls, formed when warm air rises then the air cools to dew point temp condensing onto dust particles- forming cloud droplets
- 5. large ice pellets form in cumulonimbus clouds when updrafts of air carry rain up so high, it freezes and collects snow flakes which melt and add to it's size
- 6. moist warm
- 7. When the air is so cold that water vapor changes directly into ice crystals
- 10. Composed of water droplets formed when a large layer of air is cooled to its dew point temp
- 11. Made of ice crystals, look thin and wispy, highest in the sky, point in the direction the wind is blowing.
- 13. Occurs after rain hits the ground, then it freezes on contact
Down
- 1. dry cold
- 2. cold moist
- 3. dry warm
- 4. A fast moving warm air mass overtakes a slower moving cold air mass
- 7. When rain falls through a layer of very cold and freezes before it hits the ground
- 8. a cold air front pushes into a warm air mass. the cold air stays down pushing the warm air up
- 9. Warm air trapped between 2 cold fronts. The warm air is prevented from reaching the ground and the 2 cold fronts mix together
- 12. water Vapor gets too happy in the sky
