Plate tectonics is responsible for the formation of Pacific islands. As plates move against each other, they generate friction which causes volcanic activity. Over time, the volcanic activity breaks the surface of the water and forms islands. This can take hundreds of thousands of years. The entire time, the plates are still shifting, causing this volcanic activity to create islands spreading out from the source. Hawaii is a perfect example of this activity.
The hawaiian islands were formed when the volcanic eruption spurred in the ocean floor and formed a volcano overtime. That is why Hawaii is made up of volcanoes. Also whale fossils were left behind and became part of Hawaii.
The Hawaiian-Emperor island chain consists of volcanic seamounts formed over a "hotspot" below the constantly-moving Pacific Plate. The spot is located just SE of the big island of Hawaii (which continues to grow from the magma released under it). The hotspot has existed for at least 82 million years.
The "newest" island to form over the hotspot is the Lo'ihi Seamount, which began to grow about 400,000 years ago and is still about 3000 feet underwater. It is expected to reach sea level in about another 100,000 years.
Most of the Pacific Islands have been formed by volcanoes or reefs rising above the water
the are formed from a hotspot or magma plume under the ocean. That's why they have some of the worlds most active volcanoes.
Magma rises from the Earth's core to the seafloor and erupts and accumulates to form volcanic islands.Then the island moves and a new piece of lithosphere covers the hot spot.
Volcanic activity.
By volcanic activity.
wake up u idiot
The Hawaiian Islands are formed by the ocean structures known as submarine volcanoes. They continue to build the Pacific islands.
No. The Hawaiian islands are formed by a mantle plume.
they were formed by underwater volcanoes
Hawaii was formed by centuries of volcanic magma boiling out. Hawaii and it's sister Islands are active volcanoes.
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.
Not. The Hawaiian Islands are formed at a hot spot.
It is thought that volcanoes formed the Hawaiian islands.
Volcanoes formed the Hawaiian Islands over millions and millions of years.
The Hawaiian Islands are formed by the ocean structures known as submarine volcanoes. They continue to build the Pacific islands.
From undersea volcanoes.
Volcanoes.
The oldest Hawaiian islands are Kauai and Niihau, which are believed to have formed around 5 million years ago. These islands are located in the northwest part of the Hawaiian island chain and are considered the oldest because they were the first to emerge from the volcanic activity that formed the islands.

it was formed be volcanos
The Hawaiian Islands were formed and are still being formed right now by volcanic activity.
