What is the significance of the alignment of seamounts and islands of the Hawaii-Emperor Seamount
chain and other similarly oriented alignments to the south (e.g., Tuamotu Islands and Line (Austral)
Islands)? What will be an ideal response?
All are thought to be aligned volcanic chains that were produced at hot spots. The straightness and
parallelism of these alignments is considered to represent the direction of absolute plate motion. The
bend in each chain implies that there was a relatively abrupt change in the direction of plate motion or
a clockwise rotation of the Pacific plate about 40 million years ago
