why do geologists find iceland a useful place to conduct research on seafloor spreading
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.
Making the world better, one answer at a time. Iceland is continually growing because of volcanic activity. As the lava erupts and runs into the sea, it cools and becomes solid land.
