1
fluid motion between regions of unequal heating
2
a mathematical relationship between the distance an aircraft will glide forward to the altitude loss (If an aircraft has a glide ratio of twenty to one, and it is one mile above the Earth, it should glide 20 miles before landing.) 2 word
3
the atmosphere's resistance to vertical motion
4
the average rate at which temperature decreases with an increase in altitude (The average lapse rate is 3 1/2°F per 1000 feet increase in altitude.) 2 words
5
the height or distance above a reference plane (The most common planes of reference used in aviation are heights above sea level and ground level. If it’s above average sea level, it’s referred to “MSL,” or Mean Sea Level, and if it’s above ground level, it’s referred to as “AGL.”)
6
usually a single-engined airplane that will pull a glider from the ground to an altitude where it can be released. 2 words
7
mass in a given volume (example: 12 eggs in a basket)
8
a column of air that moves upwards
9
the art of staying aloft by exploiting the energy of the atmosphere
10
a waving action with strong up and down motions started as air moves across mountain ranges (Sailplane pilots can use the motion of this wave to gain altitude.
