The hawaiian islands were formed when the pacific plate moved over?

The Hawaiian Islands were each formed over a hot spot in the Earth's crust, creating a volcano. As the Pacific Plate has moved to the northwest, new islands have been created from that same hot spot over time.

Why do some Hawaiian islands have active volcanoes and some don't?
The Hawaiian Islands are formed by volcanic activity from the Hawaiian hot spot. This hot spot causes magma to rise to the surface, creating new landmasses. The islands that currently have active volcanoes are located over the hot spot, while the older islands have moved away from it, causing their volcanoes to become dormant.
How did mount Kilauea form?
Mount Kilauea formed as a Shield Volcano, as the Pacific plate moved over a geological hot spot magma broke through the crust of the earth and formed a set of volcanic mountains on the sea floor. The tops of these mountains are now the Hawaiian islands.
Why are many of the Hawaiian islands volcanoes extinct?
Due to plate techtonics, most of the Hawaiian Islands have been moved away from the "hot spot" in the earth's crust that is slowly extruding new islands. The big Island of Hawaii is the current location of that hot spot.
Is Kilauea on a divergent boundary?
No. Kilauea was formed when the Pacific Plate moved over a hot spot in the Earth's mantle. Magma formed a plume upward into the Earth's crust and formed a volcano: Kilauea. 9 +10 = 21
Why is there only one hawaiian island with volcanic activity?
The islands of Hawaii have been formed from lava flowing up from the seafloor in the central Pacific. This "hotspot" has stayed in the same place as the ocean floor slowly moved NW due to crustal spreading. As each island moved away from the hotspot, it lost the supply of new lava from below. Only the volcanoes of the "big island" (Hawaii) and a smaller underwater seamount (Loihi) are currently spewing new lava. Eventually the big island's volcanoes will also stop as it moves off the hotspot after a few thousand years.
How did the Hawaiian Iland come into existence?
The Hawaiian Islands were formed through volcanic activity. They were created by a hot spot in the Earth's mantle, where a constant upwelling of molten rock led to the formation of a series of volcanic islands. Over millions of years, as the Pacific tectonic plate moved northwestward, new volcanoes formed, creating the entire chain of islands.
Why aren't the Hawaiian Islands in a straight line?
The Hawaiian Islands trail off to the northwest because the other Hawaiian Islands have moved northwestward beyond the hot spot.
How did kilauea form?
Mount Kilauea formed as a Shield Volcano, as the Pacific plate moved over a geological hot spot magma broke through the crust of the earth and formed a set of volcanic mountains on the sea floor. The tops of these mountains are now the Hawaiian islands.
Was the Hawaiian Islands formed by erosion?
No. They were formed by what geologist call a "hot spot" under the ocean floor. As the continental plate moved across this spot, large amounts of magma was pushed up forming the islands which stretch over a thousand miles.
How were Hawaiin islands created?
The Hawaiian Islands were created when molten material moved over a hot spot.
How was Mt Kilauea formed?
As the pacific tectonic plate moved over the hawaiian hotspot, the island chain of Hawaii was created. as the hotspot burns through the pacific plate, creating a magma chamber, volcanoes are formed. And through these eruptions, land is created from the solidified lava.
How was the island Samoa formed?
AnswerSamoa is a group of islands formed about seven million years ago in the Pacific by a series of broad shield volcanos. Those volcanoes formed as the Pacific plate moved over a stationary hotspot deep in the earth in that region. Eventually the lava broke the surface of the ocean and formed islands. Samoa has been occupied by humans for over 3,000 years.

How was Five Islands formed?
The Hawaiian Island Chain (consisting of 19 islands and atolls) are actually to tops sea-mountains known as the Hawaiian Ridge. It was form over thousands of years by volcanic activity over a "hotspot" in the Earth's mantle. Movement of the tectonic plates have moved the island chain slowly in a north by northwest direction, thus creating more islands (read mountains).
Why are many of the Hawaiian islands volcanoes extinct?
Due to plate techtonics, most of the Hawaiian Islands have been moved away from the "hot spot" in the earth's crust that is slowly extruding new islands. The big Island of Hawaii is the current location of that hot spot.
Why did Americans planters move to Hawaii?
American planters moved to Hawaii because of the fertile soil. The fertile soil came from the volcanoes beneth the islands of Hawaii.The volcanoes gave the fertile soil. To find out more on Google write Hawaiian islands
