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.
Divergent plate margins are also known as rift systems or mid-oceanic ridges. Rifts occur where two crustal plates are being ripped apart. This tear in the crust allows magma from the mantle to erupt at the surface. This process can be readily observed in Iceland which sits directly on the Atlantic mid-oceanic ridge. The island nation of Iceland was formed by the historic eruptions of volcanoes along the rift system.
