- 15. Multiple ChoiceStorms are more likely to form at the leading/eastern edge of a _______________________.cresttroughair massspecific heat
- 16. Multiple ChoiceGenerally, weather systems move across the US from west to east.truefalse
- 17. Multiple ChoiceHigh pressure areas typically have poor weather coming.truefalse
- 18. Multiple ChoiceCold air is more dense than warm air allowing cold air masses to “bulldoze” under warm air masses.truefalse

- 22. Multiple ChoiceWater has a lower specific heat than sand.truefalse
- 23. Multiple ChoiceAir density increases with an increase in altitude.truefalse
- 24. Multiple ChoiceGravity pulls air toward the center of earth creating higher air pressure at lower elevation.truefalse
- 25. Multiple ChoiceWithout an atmosphere, Earth would be a lifeless rock similar to the moon.truefalse
- 26. Multiple ChoiceNor'easters are storms that move north up the East Coast of the United States bringing strong winds and precipitation.truefalse
- 27. Multiple ChoiceHow do Chinook winds affect weather on a mountain range?Air descending from the mountains experiences adiabatic heating; as it warms it melts all the snow.Air ascending over the mountains stays aloft and is too high to precipitate.Air ascending over the mountains experiences adiabatic heating and precipitates on the top of the mountain range.None of these
