A common example is the dew that collects on grass early in the morning. Fog, raindrops, and snowflakes always begin to grow on microscopic particles carried in the air. Today, each thimbleful of air we breathe usually contains more than 100 such particles. Many billions of billions of water molecules are needed to form one water droplet. In other words, if fewer condensation nuclei existed before the flood, there might not have been rain.
Volcanoes emit large quantities of sulfur into the atmosphere.
Various compounds of sulfur are then formed which act as condensation nuclei. DMS escapes into the air and quickly oxidizes to form condensation nuclei. Thus, most condensation nuclei needed for rain are compounds of sulfur 2 and can be traced back to volcanoes. Consequently, if volcanoes began during the flood, it is quite likely that rain did also. Instead, they formed by fragmenting and atomizing the upward-jetting subterranean waters.
