설명
Rain is a form of atmospheric precipitation composed of water droplets that have condensed from atmospheric water vapor and fall by gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. — 영문 출처: Wikipedia
