Snow are able to grow to hundreds of micrometers or millimeters in size at the expense of the water droplets by the Wegener–Bergeron–Findeisen process. The corresponding depletion of water vapor causes the ice crystals to grow at the droplets' expense. These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates. These aggregates are snowflakes, and are usually the type of ice particle that falls to the ground. Although the ice is clear, scattering of light by the crystal facets and hollows/imperfections mean
Frozen yogurt Frozen yogurt Frozen yogurt (also spelled frozen yoghurt; also known as frogurt or by the tradename Froyo ) is a frozen dessert made with yogurt and sometimes other dairy products and non-dairy products. It is usually more tart than ice cream, as well as lower in fat (due to the use of milk instead of cream).
