Volcano >> lithosphere >> atmosphere >> hydrosphere >> biosphere. Volcanoes (an event in the lithosphere) 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). Particulate matter in the air (atmosphere) falls out, initially smothering plants (biosphere), but ultimately enriching the soil (lithosphere) and thereby stimulating plant growth
(biosphere).Volcano >> lithosphere >> hydrosphere >> biosphere. Volcanoes (events in the lithosphere) may release a substantial amount of hot lava (lithosphere), which causes mountain glaciers (hydrosphere) to melt. Mudflows (lithosphere) and flooding may occur downstream from volcanoes and may inundate streamside communities (biosphere).
Volcano >>lithosphere >> atmosphere >> biosphere >> lithosphere Volcanoes (events of the lithosphere) release a large amount of carbon dioxide (atmosphere), the raw material for sugar production in plants (biosphere). This may increase photosynthetic production and eventually increase the amount of biomass, which, after a very long time, forms coal and oil deposits (lithosphere).
Volcano >> complex interactions Volcanoes (lithosphere) may emit large quantities of sulfur dioxide (atmosphere). When atmospheric sulfur dioxide combines with water (hydrosphere), sulfuric and sulfurous acid form. Rain (hydrosphere) may bring these acids to the Earth, acidifying soils (lithosphere), lakes and rivers (hydrosphere).
Acidic water leaches nutrients from the soil (lithosphere) into the water table (hydrosphere), making the soil less fertile for plants (biosphere), and the subterranean water supply (hydrosphere) less potable for humans (biosphere).
Acid rain falling on lakes and streams reduces the pH of the water (hydrosphere), which may result in a decrease in phytoplankton and zooplankton growth (biosphere). If photosynthesis is reduced, atmospheric concentrations of carbon dioxide can build up and stimulate global warming (atmosphere) which may contribute to increased melting of glaciers (hydrosphere).
