1. A dim, fuzzy patch of light called a “watery sun” characterizes a(n) altostratus cloud.
   
   
2. A(n) evaporation fog results when air rising off of a warm, moist surface mixes with cooler air, causing the air to become saturated.
   
   
3. Cloud formation is enhanced along a mountain ridge by a process called orographic lifting.
   
   
4. An air parcel that sinks down the lee side of a mountain undergoes adiabatic compression, which causes the air to warm up even though no heat is being added to the air.
   
   
5. In order for precipitation to fall, drops inside of clouds must grow so their terminal velocity is greater than the speed of the cloud’s updraft.
