What else can I help you with?
Are the active Hawaiian volcanoes situated directly above a major boundary between two of the Earth's largest tectonic plates?
No. The Hawaiian Islands are situated directly above what's called a "hot spot." A hot spot is an area under the tectonic plate where magma gathers, gradually gaining pressure until it's released above the surface forming volcanoes and subsequently islands.
Where is the hot zone located?
Hot spots are a concentrated area of the upwelling of magma. This causes mantle plumes above these hotspots. The Hawaiian Islands are an example of this occurence, as the hotspot forms multiple volcanic islands in a neat row when the plate above it moves over it.
Name ansd locate two archipelagos?
The Galapagos Islands is an archipelago located in the Pacific Ocean, off the coast of Ecuador. The Hawaiian Islands is another archipelago located in the central Pacific Ocean, southwest of the United States.
Why do some Hawaiian islands have active volcanoes and some don't?
All of the Hawaiian islands are volcanic in origin. The volcanoes are fed by a hot spot, where extra hot material wells up in the mantle, generating magma. This hot spot generally stays in one place while the Pacific Plate above it moves. As this happens, older volcanoes are carried away from the hot spot and lose their source of magma.
How the Hawaiian Islands originated?
An underwater volcano which currently is under and slighty off shore of the island of Hawai'i (the big island). The lava would breach the surface of the ocean, create land and after a while the 'island' would drift. the process would start again, create an island and it would drift. All of the Hawaiian islands were at one point in time, above that underwater volcano. If you look at a map, you will see that even beyond the main Hawaiian islands there is a looong chain of islands. They once originated above that same volcano and eventually after drifting, sank slightly. All of the Hawaiian islands are slowly sinking as they drift as well. It will take perhaps half a million years but the island known as Hawai'i will one day be much smaller. There will be other islands in place by then though, such as the island currently off the shore of Hawai'i island that is currently being made.
What island is located off the west coast of Peru?
The small group of islands off the west coast of Ecuador above Peru are the Galapagos Islands.
What happens when the plates form mount vesuvius?
Mount Vesuvius is located above a subduction zone formed where the African plate descends beneath Italy.
What continent is indonesea located?
its a group of islands in the lower the hemisphere under Asia above Australia
The Hawaiian Islands are formed by these ocean structures?
sea mountsThe Hawaiian islands were formed by volcanoes. Volcanoes have two methods of formation, convergence of tectonic plates at the edges of the plates, and hot spots under the middle of plates. The Hawaiian islands and others in that area were formed when magma from the mantle rose to Earth's surface through a certain spot in the middle of the plate (i.e., the Pacific Plate for the Hawaiian Islands). This hot spot is situated beneath the center of the plate, and the volcano above moves with the plate as it moves, but the hot spot stays in place. This causes the original volcano to become extinct when its move cuts it off from its magma source and an island is born. A new volcano will then form above the hot spot again. This process repeats as the plate moves and a string of volcanoes (and eventually, islands) will dot the surface of the plate as the movement continues away from the hot spot.

In what ocean is Maderia located?
Madeira is a Portuguese archipelago that is in the north Atlantic ocean, above the Canary Islands. It includes the islands of Madeira, Porto Santo, and the Desertas.
What are the beneficial products of volcanic activity?
The beneficial products of volcanic activity is that the earth/soil will be filled with nutrients. yeah and: the hawaiian islands geothermal energy and what was written up above sheep_dog/is*me (:
