Why Does Rain Happen?Rain is a natural phenomenon that occurs when water vapor in the atmosphere condenses and falls to the ground. It begins with the process of evaporation, where heat from the sun causes water from oceans rivers, and lakes to turn into vapor. This vapor rises into the atmosphere and cools down. As it cools, the vapor condenses into tiny water droplets forming clouds. When these droplets combine and grow larger, they become too heavy to stay in the air. Eventually, they fall to the ground as rain. Rain is essential for life on Earth, as it provides fresh water for plants, animals, and humans. It also helps regulate temperature and maintain the balance of ecosystems What is the first step in the process of rain? a The condensation of water vapor into droplets b The combination of water droplets into clouds C The evaporation of water from oceans, rivers, and lakes d The falling of heavy droplets to the ground E The regulation of Earth's temperature by rain
