Rainwater is the water that falls from the atmosphere as precipitation. It forms when water vapor condenses into droplets in clouds and eventually becomes heavy enough to fall to the ground. Rainwater is a crucial part of the Earth's water cycle, replenishing rivers, lakes, and groundwater supplies. Collecting and using rainwater can be beneficial for various purposes, such as irrigation and drinking. Many people use rainwater harvesting systems to capture and store this natural resource. This practice can help conserve water and reduce reliance on municipal water supplies, especially in areas prone to drought.
