The hot spots in the oceanic crust are caused by upwellings of hotter material (known as mantle plumes) in the mantle below the crust.

Do hot spots only form in oceanic crust?

No, hot spots can form in both oceanic and continental crust. Hot spots are areas of high volcanic activity that are thought to be caused by a deep-seated mantle plume that rises to the surface, creating a localized area of magma upwelling. These hot spots can create volcanic islands, such as the Hawaiian Islands, regardless of whether they are in oceanic or continental crust.


Do hot spots form only under oceanic crust?

No, there is a hot spot underyellowstone


What are Hawaiian Lava Beds made out of?

magma from hot spots in the crust


Can hot-spots cause earthquakes?

movements due occur on land cause by a hot spots. a good example is kilauea in hawaii. its still rumbling because its on the hot spot. so yes, hot spots can generate an earthquake depending on the movement of the plates.


Do hot spots create or destroy oceanic or continental crust?

Hot spots do not create or destroy oceanic or continental crust. Hot spots are volcanic regions that are stationary relative to moving tectonic plates. As the plates move over the hot spot, they experience volcanic activity, which can result in the formation of volcanic islands or seamounts, but the crust itself is not created or destroyed in the process.


Is volcanic activity on Venus caused by plate tectonics?

No. Scientists believe that the crust of Venus is too thick to support plate tectonics. Volcanic activity is likely driven by hot spots.


What is the cause of the volcanoes in Hawaii?

The volcanoes in both Yellowstone and Hawaii are associated with hot spots. These are areas of especially hot mantle where some melting occurs. In Hawaii the hot spot melts oceanic crust, creating basaltic magma that most erupts effusively. In Yellowstone the hot spot melts continental crust, creating viscous rhyolitic magma that erupts explosively.


What are the deccan plateau hot spots and hawaii hot spots examples of?

They are examples of the flow of heat from the interior of the Earth to the surface through a fixed spot in the mantle which melts through the moving crust. Better known as a 'hot spot'.


What causes hot spots in brake rotors?

Hot spots are caused by over heating the rotors Causes: "riding" the brakes, faulty brake components, general abuse


Convection currents in the earths crust causes volcanos?

No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.


What supports the sea floor spreading theory?

In short, no. Most volcanoes are located in the ring of fire, which surrounds the Pacific Ocean. Most volcanoes are caused by subduction, which is when one plate is pulled under another. This is usually ocean crust under a continent which then melts and comes back to the surface as magma. Other volcanoes are hot spots caused by weak spots in the Earth's crust, such as the hot spot that created Hawaii.


What is an unusually hot area deep in Earths mantle that melts the crust above it and forms a volcano?

A hot spot. An example of a hot spot are the islands in Hawaii which were made from hot spots.
