The right option is; formation of snow

Formation of snow is a process in which the atmosphere interacts with the cryosphere.

The cryosphere is the part of the earth's surface where water is in solid form. The temperature of the cryosphere is very low which freezes water, and convert it into ice. The cryosphere include river ice, frozen ground, sea ice, lake ice, glaciers and snow cover. The atmosphere interacts with the cryosphere when there is formation of snow. Snow is formed when small ice crystals in the atmosphere joins together to become snowflakes. The snowflakes is then turned into non sticky powdery snow when it falls through dry cold air in the atmosphere.
