What is the nature of the relative movement of plates and hot spots? Briefly explain which is fixed and which is moving. Also explain how the Hawaiian-Emperor island chain was formed. Part of being a scientist is questioning everything and testing everything. Thinking creatively, what are two possible reasons for the bend in the island chain? Briefly explain how you could test these two ideas.

What will be an ideal response?


The Pacific plate is moving over the hot spot. The plume of magma has formed the Hawaiian- Emperor seamount chain as the plate has continued to move. The bend at Kimmei could have been caused by the movement of the plate changing or the plume itself moving. To test this, you could look at the motion of the plate at other locations between 48 and 27 mya.
