The process of water falling from the sky as rain, sleet, snow, or hail is known as precipitation or rainfall. It can fall in a constant stream or in sporadic bursts, be light, heavy, or somewhere in between. Rainfall is a crucial component of the water cycle since it refills the water supply on Earth and aids in the survival of plant and animal life. It can also have a big effect on the ecosystem since droughts and landslides can result from a lack of rain, while large rains can produce flooding and landslides. The sound of raindrops hitting the ground or a roof is frequently thought to be calming and pleasant when it rains.
