Document Summary
Discovery and exploration of deep sea vents: alfred wegener 1912 put forth the controversial idea of continental displacement or continental drift . In 1977 while examining sea floor spreading for evidence of tectonic plate movement in the area of the galapagos. Rift dr. jack corliss found dense fields of peculiar animals: region where hot magna builds new crustal material, it also heats water to high temp, 300 c + and generates mineral rich water, thermal springs on the ocean floor. = at these vents you find chimney like structures of metal that are coming out of the mantel and forming chimneys from these chimneys, they are spouting hot water. Worm resides in the whiteish base a hard shell-like worm. No: bacteria are the primary producers in fact none of them do, bacteria turn out to be the sulphur metabolizers, autotrophs! Some species have developed symbiotic relationships with bacteria, nutrients are exchanged between species.
