volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
