Title: Cave Formation: Biogeochemical Cycles
Url: http://www.teachersdomain.org/resource/ess05.sci.ess.earthsys.cavebio...
Publisher: WGBH Educational Foundation
Description: This video explores the role of biogeochemical cycles in the formation of caves. It discusses a radical new theory that identifies sulfuric acid as a cave-forming agent. The video, adapted from a NOVA broadcast, identifies the source of the sulfuric acid, which, unlike carbonic acid, the typical cave-forming agent, does not readily form in nature. The segment is 5 minutes and forty seconds in length.
