It is also said that he thought that the rectangular chambers looked like the cells in some monasteries. Physically cells always have a boundary membrane, a little like a polythene bag encloses contents within it. Inside the space limited by the membrane there is an remarkable chemical processing unit.
Iceland is a place where, because of large amounts of lava extrusion, the ocean floor is, in effect, above sea level, making it easy to study ocean floor spreading. You can affix strain gauges on many parts of the spreading ridge. 6 people found this useful.
Chemically, rocks in Iceland reflect their origin at a hot spot in the middle of the ocean. Another such hot spot-they are 25-30 in all-is Hawaii in the Pacific Ocean which is characterised by many of the same types of rock as Iceland. There is, however, one interesting exception:(dacite and rhyolite) are much more common in Iceland than in Hawaii, where such rocks are almost totally absent, and in fact Iceland is probably quite unique among oceanic islands in this respect.sked By.
