Do hot spots only form in oceanic crust?
no they also occur up your mom
What are hot spots in the crust caused by?
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 create or destroy oceanic or continental crust?
Create
Is the following sentence true or false Hot spots form only under oceanic crust?
false there is a famous hotspot in Yellow stone, CA
Why does one continental plate slide under the other?
Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust

What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
Why are hot spot volcanoes more common where the mantle plume underlies an oceanic plate?
The crust of an oceanic plate is generally thinner that the crust of a continental plate.
What type of lava comes from hot-spots?
It depends on where the hot spot is located. Felsic magma would be produced if it was under a continent (such as in Yellowstone) whereas Mafic magma would be produced if it was under oceanic crust (such as in Hawaii)
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.
How are volcanoes different from volcanoes in other places?
Hot spot volcanoes such as those in Hawaii and the Yellowstone Caldera form as a result of extra hot material rising from deep within the mantle. While most volcanoes can only form near plate boundaries, hot spot volcanoes can form in the middle of a tectonic plate. Unlike at subduction zones, which are generally associated with stratovolcanoes, hot spots that form under oceanic crust typically produce shield volcanoes. Hot spots under continental crust can be more complicated and have produced every variety of volcano.
Is a hot spot found at converging oceanic plates?
Hot spots are usually found away from plate boundaries.
