Answer to Question 1

Answer: Horizontally developed clouds are indicative of the slow rise of stable air. Vertically developed clouds point to instability because of the faster, higher rise of air.

Answer to Question 2

Answer: In clouds with mixtures of ice crystals and water droplets, ice crystals grow at the expense of the water droplets because the saturation vapor pressure is lower over ice than liquid water. This makes ice fall so that precipitation starts as snow in such clouds.
