Sleet: Freezing rain into small ice crystals sometime with rain
Snow: Frozen ice crystals that form directly from the cloud vapor and fall as snow
Graupel: Snow covered with frozen water vapor usually fragile to the touch. Often called Soft Hail or Hard snow.
Hail: Water vapor forzen solid usually around a nucleus of snow or sleet or graupel. Usually, the hail has made many up and down trips inside the cloud due to updrafts causing more and more layers of ice to form until the updraft is no longer able to keep it aloft and it falls to earth.
