hot spot volcanism. The round iSales 
One of the oldest theories and greater acceptance, the origin of the volcanic islands is called the hot spot theory, consisting of volcanism attributed to the existence of a zone in the mantle, which keeps for a long period of time a much higher temperature than the surrounding areas This causes a perforation of the bark immediately above and hence volcanism. Usually simile is used to saucepan of boiling water to explain the ascent of magma in this way the water would rise from the bottom of the container to its surface to receive heat from the stove, the analogy is clear still water surface crust.
To continue the experimental method carried out so far will use a simulation (homegrown) allowed as in the past to trace the wavefront analyzing the side fronts and their interactions, which as we know match the address the levees volcánicos.En photography you can see, the effects on water surface aerator bubble diffuser fitted, of which are used in aquariums, the simulation is like the pot of boiling water, with the advantage that bubbles facilitate the monitoring of the lines of force generated by the interaction of the front side, as the air bubbles oriented along the direction given by them in the levees.
Considering the above we can conclude that the hotspot volcanic islands have the shape of the island in the drawing (this is a fictional island) in which the configuration of the dikes is indicated, ie an island hot spot will form levees circular radial position (not to be confused with the islands round the previous article) or in any case would form star because of erosion, something like the picture of sun rays with very marked, with which this article illustrate the latter would be the equivalent of the simile of the air diffuser made with light, (this time I did not use the laser that it was necessary to aim directly at the camera lens and the direct reflex viewfinder can be dangerous to the eye, or for the chip of the camera)
For desert, the Great Island (main island Hawaiian) volcanism which led to the hot spot theory, considering the perfect example of this, this island has a tripod structure, such as Tenerife, La Palma or iron (it is known as three-pointed star) and the ridges or arms of this structure (which in the Canary Islands called dorsal or peaks) in Hawaii was called rifts.
As I said the Hawaiian Islands of great importance for the theory of the hot spot has a tripod structure common on other islands, nothing matched with theoretical expectations, it goes without saying that there is no island on this planet circular dikes radial and the hypothetical island drawing so I conclude that the theory of the hot spot can be classified as a myth the same level as the mythical Atlantis to which attributes the origin of the Canary archipelago.
