How does atmospheric (or barometric) pressure change as the altitude increases?
a. Pressure and altitude are directly related; when altitude increases, pressure increases
b. Pressure and altitude are inversely related; when altitude increases, pressure decreases
c. Pressure and altitude are inversely related; as altitude increases every 5500m, pressure decreases by 1/2.
d. Pressure and altitude are not directly related; when altitude increases, pressure is not affected
e. Both B and C
