Answer 2

• According to the USGS, all clouds are made up of water vapour and moisture particles. When the droplets come into touch with something solid, such as a dust or smoke  particle,they wrap around it and expand.
• Droplets can also collide with one another,resulting in a bigger particle with more mass.
• When a droplet's weight leads  it to descend faster than the air's updraft current, it becomes precipitation and falls to the ground. According to the USGS, one drop of rain water is made up of  millions of droplets.
• Areas that receive a lot of rain can capture the surplus water and use it to their benefit. Showering, toilet flushing, and agricultural irrigation with rainwater helps to save the public supply of purified drinkable water.
• People all around the globe capture rainwater, according to the University of Oregon's Center for the Advancement of Sustainable Living, but it's uncommon in the United States despite its practical benefits.
• Using gutters, downspouts,  and a storage tank to create a catchment system can help you lessen your reliance on traditional water sources and take use of a renewable natural resource.
