fallout

Examples of fallout in the following topics:

• The Sulfur Cycle

  • Sulfur is deposited on land as precipitation, fallout, and rock weathering, and reintroduced when organisms decompose.
  • On land, sulfur is deposited in four major ways: precipitation, direct fallout from the atmosphere, rock weathering, and decomposition of organic materials.
  • Sulfur can also fall directly from the atmosphere in a process called fallout.
  • Sulfur enters the ocean via runoff from land, fallout, and underwater geothermal vents.
  • Sulfur dioxide from the atmosphere becomes available to terrestrial and marine ecosystems when it is dissolved in precipitation as weak sulfuric acid or when it falls directly to the earth as fallout.
