Occasionally the booms with the lights would bump into things and that would stretch some of the components wed have to fix them at night, says Strickrott. Finding dazzling communities of creatures living in an ecosystem that doesnt rely on sunlight has overturned fundamental assumptions about the origins of life.

Slow Volcanoes of the Deep Sea is a 2003 documentary film in the IMAX format about undersea volcanoes directed by Stephen Low . You get in your Magic School Bus, drive down the throat of a volcano, and find that you are driving through melted rock that flows with much greater difficulty than does most melted rock, because the melted rock you are driving through is lumpier than typical for melted rock. c. transform D) Azores e.

B) Hot spots e. When the same mineral appears in different metamorphic facies. The sites are like no other place on Earth. b. Perhaps the most radical difference between this ecosystem and those found elsewhere on the planet is that it is based, not on photosynthesis, but on chemosynthesis.

Nobody knows how far down they go but some scientists believe that the biomass (the combined weight) of these microbes and those living throughout the Earths crust, may be greater than the biomass of every other living thing on Earth. b. divergent plate boundaries This finding was pivotal to the theory of plate tectonics. Until a few years ago, no human being had any idea that any of these organisms existed. Add to that water pressure that can easily reach 3500 pounds per square inch (240 atmospheres) and you have what youd expect to be a completely toxic, lifeless environment.
