A raindrop is a small droplet of water that falls from clouds during precipitation. It forms when water vapor in the atmosphere condenses into liquid droplets, which can vary in size. Raindrops typically have a spherical shape due to surface tension, although they can become more flattened as they fall through the air. Raindrops are essential for the water cycle, contributing to the replenishment of groundwater and surface water bodies. They provide moisture for plants and are crucial for agriculture. The process of raindrop formation and fall is influenced by factors such as temperature, humidity, and wind, which are all part of weather patterns.
