Why do volcanoes at hot spots eventually become extinct?
As the tectonic plate moves, the volcano above the hot spot moves away from the magma source, causing it to become cut off from its energy supply and eventually go dormant. Without a continuous source of magma to fuel eruptions, the volcano gradually becomes extinct.
When will a hot spot volcano become extinct?
when the volcano is carried away from the hot spot by the tectonic plate. Since volcanoes form on or between plates they move with the plate. You probably know that a hot spot forms in the middle of a plate because of the mantle layer bursting through the crust . As the plates shifts so does the volcanoes. Look at the Hawaiian islands Only the big island of Hawaii is still active and then there are all the other islands behind the big one. This is becuase of the tectonic plates shifting downwards
Are all volcanoes in Hawaii active?
Any volcano that has erupted within the Holocene epoch (i.e. within the past 12,000 years) is considered to be active.Some examples of active volcanoes are Mount Etna in Sicily, Kilauea in Hawaii, Mount St. Helens in the US, Mount Pinatubo in the Philippines, Krakatoa in Indonesia and Mount Vesuvius in Italy.
How will new islands in the hawaiian chain form in the future because of hot-spot volcanism?
While the Hawaiian hot spot stays in one place, the Pacific Plate moves over it and will eventually move the currently active volcanoes away from it. The magma will find new ways through the crust and erupt on the seafloor to form new volcanoes that will eventually build into 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.

Would volcanoes form at a hot spot?
Yes, they would. Hawaii is a prime example; all of its islands are either extinct or active volcanoes.

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.
How will new islands in the hawaiian chain form in the future because of hot-spot volcanism?
While the Hawaiian hot spot stays in one place, the Pacific Plate moves over it and will eventually move the currently active volcanoes away from it. The magma will find new ways through the crust and erupt on the seafloor to form new volcanoes that will eventually build into islands.
In plate tectonic theory what does a hot spot create?
A hot spot is an area of volcanic activity that occurs independently of tectonic plate boundaries. As a tectonic plate moves over a hot spot, a linear chain of volcanoes forms on the plate surface. The most well-known example of this is 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.
What will eventually happen to the active volcanoes on island of Hawaii which is now over the hot spots?
Hawaii sits on the moving Pacific plate. Beneath it is a powerful hot spot. Eventually, the plates movement will carry the island of hawaii away from the hot spot.
What do you call volcanoes that aren't on plate boundary edges?
Such volcanoes are hot spot volcanoes.
How do volcanoes form there?
its a hot spot
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.
