How does an island chain form over geologic hot spot?
A Hot spot is stationary in time and burns though the solid lithosphere creating an island through volcanic eruptions. The lithosphere is separated into plates that move around so if a hot spot occurs under an oceanic plate it forms a island and as the plate moves (and the hot spot does not) it forms a chain of islands (as the plate moves over the hot spot). This is how the Hawaiian chain is formed.
How do you briefly explain how volcanoes that are located in hot spots formed?
As tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
How did the Hawaiian Islands form?
Volcanoes - It is called a hot spot and as the earths crust moves over the spot, volcanoes form and in this case, created the chain of islands.They formed from a hot spot in earths crustThe Hawiian Islands are the tops of huge undersea volcanoes.The way the islands have formed, although far away from any fault, the area is a volcanic hot-spot. Back a couple million years, the crust beneath was thinning and rising. A series of undersea volcanic eruptions force volcanic material upwards, making the islands. The thinning of the crust, literally, moves southward to make other islands.It has to do wih tectonic plates
When a hot spot stays put but the plate above it keeps moving what happens?
It leaves an island arc or chain if the hot spot is in the ocean. A great example of this is the Hawaiian Island chain. There is another hot spot in the North American plate which now resides in Yellowstone National park. This hot spot simply leaves a chain of extinct volcanic areas as the continental plate moves over it.
Is Hawaii considered a hot spot for volcanic activity because it does not lie on the plate boundaries?
Yes. --Hawaii moves with the Pacific Plate, and (after thousands of years) the volcanoes move away from the hot spot. As a result, there is a long chain of extinct volcanoes behind the Big Island
What chain of islands are formed because of a hot spot?
A Hot spot is stationary in time and burns though the solid lithosphere creating an island through volcanic eruptions.

How are archipelagos formed?
Archipelagos are usually volcanic, forming along island arcs produced by subduction zones (or hot spots). They formed by tectonic activities when a tectonic plate moves over a hot- spot. the lava gets pushed and when there is enough, it rises to the surface of the water. as it cools it forms a pile (an island). the volcanic activity then stops but the plate carries on moving. so when it starts again, a new island is formed.... There are other processes involved in their construction: erosion, deposition and land elevation.
How is Hawaii a volcano?
AnswerHawaii is a volcanic chain of islands formed over a 'hot spot' in the Earth's mantle. As the Pacific tectonic plate slowly moves over the hot spot, volcanoes rise from the seafloor, forming the islands. A new, future Hawaiian island is rising from the seafloor at this time. As the islands move away from the hot spot, the volcanoes become dormant, resulting in a chain of eroding mountains.

What does a coral attol surround?
as a volcanic island moves further away from its hot spot it is worn down by the weather.it can also slowly sink.
How are the Hawaiian Islands formed?
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.
How do you describe the Philippines as an archipelago?
An archipelago is a geographical series of islands usually formed when a volcanic 'hot spot' beneath the Earth's crust punches out a new island which rises to above sea level. As plate tectonics, or continental drift, slowly moves the island along with the plate. A new island can be created above the hot spot in the same place as the previous island and in this way a string or 'archipelago' is slowly created.
If a tectonic plate moves westward over a hot spot the youngest volcanic island what will the oldest volcano be?
A volcano. :p. A STOP SLACKING A STUDY PEEPS. CHEEZUZ '-'
