The "big bend" in the Hawaii-Emperor seamount chain occurred at about 45 million years ago.What is the most likely explanation for this change in the orientation of the hot spot track across the Pacific plate?
A) From Cretaceous through 45 million years (Eocene) , the Pacific seafloor used to move northwards as it subducted down a trench near the present Aleutians.Since then the Kurile-Kamchatka trench began subducting and the Pacific plate began moving NW instead.
B) The hot spot abruptly changed its direction.It used to move straight south, and since 45 million years ago it has been moving SE through the upper mantle.
C) They are two unrelated hot spot tracks that intersect.Originally there was an Emperor hot spot, then it died while the Hawaiian hot spot started up and moved in a new direction.
D) The Devil put this line of volcanoes here to confuse us and subvert us from the true path.Everyone knows Earth isn't really that old.
