WebOn top of hotspots there is generally a 20-100% molten layer at the depth of 5-20 km, which supplies sufficient material for eruptions. Iceland is home to more than 100 volcanoes, around 35 of which have erupted in recent history. The volcanism on Iceland is attributed to the combination of Mid-Atlantic Ridge activity and hotspot activity.

Web1 apr. 2010 · Scientists use the magnetic polarity of the sea floor to determine the age. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. The tectonic plates are constantly in motion and new surfaces are always being created.
