7 Written Questions

1. ice crystals formed by sublimation of water vapor on a relatively cold surface like grass, cars, etc.
2. the temperature above freezing to which air must be cooled to reach saturation.
3. a boundary that exists between air masses with different temperatures and/or water vapor concentrations.
4. a process by which air reaches saturation by being forced up and over mountains.
5. a boundary in which a cold air mass is overtaking a warm air mass.
6. a boundary that forms when a cold front overtakes a warm front.
7. a nearly motionless boundary between a cold air mass and a warm air mass. Winds blow parallel to the front, but in opposite directions on the two sides of the front.
