how are clouds formed ? when do the water droplets fall down as rain ?
Answers
Explanation:
Clouds form when the invisible water vapour in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapour. There are also tiny particles floating around in the air – such as salt and dust – these are called aerosols. Aerosols make it easier for the water vapour to condense, and once the process starts, eventually bigger water droplets form around the aerosol particles, and these water droplets start to merge with other droplets, forming clouds.
Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.

Answer:
Clouds form when air becomes saturated, or filled, with water vapor. The rain cloud appears black or gray. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
