Snow, the solid form of water that crystallizes in the atmosphere and, falling to the Earth, covers, permanently or temporarily, about 23 percent of the Earth’s surface.
Winter is the coldest season of the year in polar and temperate zones (winter does not occur in most of the tropical zone). It occurs after autumn and before spring in each year. Winter is caused by the axis of the Earth in that hemisphere being oriented away from the Sun.
In many regions, winter is associated with snow and freezing temperatures.
Every year World Photography Day is observed on August 19th to celebrate this beautiful art.
