What are the purposes of cloud seeding?
Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere, providing a base for for snowflakes or raindrops to form.
What are the positive effects of cloud seeding?
If cloud seeding is implemented, there will be increased harvesting and more food available from a wide variety of crops for the ever-growing human population. The process also has the potential to improve biomes, allow for more fertility and create more farming land and land that could be used to build better homes.
Which gas is used for artificial rain?
The most common chemicals used for cloud seeding include silver iodide,potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used.
How does cloud seeding affect the weather?
When the molecules huddle together, they form larger, heavier droplets. Eventually, they become heavy enough to fall to the ground as precipitation. Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding adds small, ice-like particles to clouds.
What are the advantages and disadvantages of cloud seeding?

How do you stop the rain superstition?
Rain Rain Make It Go Away
Either way you believe most would prefer not to have rain on their special day and that your luck is just an old wives tail. Many believe if you want to stop the rain, just boil some rocks or hang up some rosary beads in your window the night before your wedding, and rain is sure to stay away.
How do you make rain clouds?
- Fill a clear cup with water.
- Add a layer of shaving cream.
- Add several drops of food coloring.
- When the cloud gets too heavy, the drops fall through as rain! Explain to your child that when water droplets grow heavy in the sky, gravity pulls them down from the clouds as rain, just like in the experiment.
Does Canada use cloud seeding?
Cloud seeding is used as a part of weather modification programs in countries around the world to attempt to do things like steering precipitation to drought-prone areas, or to enhance snowpack on ski hills. In Canada, it’s often used to try to lessen the impact of hailstorms.
