11. Precipitation Moisture cools and condenses. Think of sweat on a drink bottle. 3 types 1.Convectional Sun heats the moist air and rain clouds form. Usually tropical. 2.Orographic Mountains force moist air upwards and rain or snow forms when moisture cools. Precipitation typically falls on windward side of mountain (the side on which wind is blowing) since it’s blocked by the mountain from falling on the other side. Rain shadow.

12. Snow No Snow
