The term 'cold covering' can refer to a variety of different things. One of the most common is a type of weather phenomenon, which can include RIME (4 letters), FROST (5 letters), SNOW (4 letters), and icecap (6 letters). RIME is a type of white ice that forms when water droplets freeze on surfaces. FROST is a thin layer of ice crystals that form on cold surfaces. SNOW is a type of precipitation in the form of flakes of crystalline water ice. An icecap is a large mass of ice that covers a large area of land or sea. All of these are examples of cold coverings that can be found in nature.
