One interesting fact about rain is that every second, around 16 million tons of water evaporate from the Earth's surface, and then the same amount falls back to earth in the same amount of time. Water moves throughout the Earth's atmosphere to keep balance. Another interesting fact is that the wettest state in the United States is Louisiana as it receives around 56 inches of rainfall each year.
Surprisingly, the driest continent is Antarctica. The area that receives the highest amount of rainfall is Cherrapunji, India where 87 feet of rain a year is common. While rain and other forms of precipitation nourish the earth to grow plants, rain also causes dangerous floods and mudslides. Another perk of rain is that it helps create electricity through hydropower. Forests that receive a lot of rain are called rainforests. Depending on the size of the droplet and the wind speed, rain can fall as fast as 22 miles per hour. Ultimately, all rain starts as snow or ice crystals in the clouds. Acid rain, caused by pollution, can release harmful elements into the air that are hazardous to animals and plants.
Earth is not the only planet that experiences rain; however, it looks very different on other planets. Venus rains sulfuric acid that evaporates before it reaches the surface.
