How are the Hawaiian Island chain and the Emperor seamount chain related?
The Hawaiian Islands were formed by volcanic activity. The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or submerged seamount in the chain is successively older toward the northwest.
What does the Hawaiian island Emperor seamount chain indicate about past movement of the Pacific Plate?
The volcanoes in the Hawaiian Island-Emperor Seamount chain get progressively older as one heads northwestward from Hawaii. These age relationships suggest that the Pacific Plate has been steadily moving northwestward, while the underlying mantle plume has remained relatively stationary.
What is the Hawaiian Islands Emperor Seamounts chain what does it tell us what is a seamount?
The Hawaiian Ridge-Emperor Seamounts chain extends some 6,000 km from the “Big Island” of Hawaii to the Aleutian Trench off Alaska. The Hawaiian Islands themselves are a very small part of the chain and are the youngest islands in the immense, mostly submarine mountain chain composed of more than 80 volcanoes.
What are the Hawaiian Emperor chain of islands and underwater seamounts?
The Hawaiian–Emperor seamount chain is the Hawaiian Islands and the Emperor Seamounts: together they form a vast underwater mountain region of islands, seamounts, atolls, shallows, banks and reefs. The line goes southeast to northwest beneath the northern Pacific Ocean; and many of the underwater mountains are guyots.
How does the formation of the Hawaiian-Emperor island chain help in the understanding of tectonics?
(b) How does the formation of the Hawaiian-Emperor island chain help in the understanding of tectonics? Motion of the Pacific plate allowed volcanic hot-spots to punch through the crust. It is an example of tectonics and volcanism working together to form mountains.
What caused the bend in the Emperor Seamount chain and the Hawaiian island chain?
The mechanism causing the unique, sharp bend in the spectacular Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney and Caltech. Rapid southward motion of the Hawaiian plume, followed by a sharp slowdown, causes the sharp bend in the Hawaiian-Emperor seamount chain.
What does the Hawaiian Island Emperor seamount chain indicate about past movement of the Pacific Plate quizlet?
What does the Hawaiian Island-Emperor Seamount chain indicate about past movement of the Pacific plate? The Pacific plate changed direction of movement about 50 million years ago. Which of the following theories about continents and ocean basins is correct?
When the Emperor seamount chain was formed which way was the Pacific Plate moving?
Immediately after subduction started, the subduction zone began moving north, pulling the island arc and the Pacific Plate north with it. This northward migration continued from 80 to 50 million years, at which time the Emperor Chain was formed by the northern drift of the Pacific over the mantle plume.
What two reasons have been stated to explain the bend in the Hawaiian and Emperor seamount island chains in the Pacific Ocean?
How are Emperor seamounts formed?
In 1963, geologist John Tuzo Wilson hypothesized the origins of the Hawaiian–Emperor seamount chain, explaining that they were created by a hotspot of volcanic activity that was essentially stationary as the Pacific tectonic plate drifted in a northwesterly direction, leaving a trail of increasingly eroded volcanic …
How does the formation of the Hawaiian-Emperor island chain help in the understanding of tectonics quizlet?
How does the formation of the Hawaiian-Emperor island chain help in the understanding of tectonics? It shows that mountain building can occur on the ocean floor as well on the surface of Earth. It is an example of tectonics and volcanism working together to form mountains.
What is the hypothesis for the change in direction of the Hawaiian-Emperor seamount chain?
