The volcanoes of Hawaii
A hot spot is an area where extra hot mantle material wells up from deep inside the mantle, forming magma that can lead to the formation of volcanoes. An eruption is an event in which a volcano ejects ash, gas, or molten rock. Most volcanoes are not associated with hot spots.
Mantle plumes
The term hot spot is used to describe a very long-lived magma source located deep in the mantle. J. Tuzo Wilson is credited with having originated the concept of hot spots.
The hot spots in the oceanic crust are caused by upwellings of hotter material (known as mantle plumes) in the mantle below the crust.
Correct. About 90% of volcanoes are associated with plate boundaries. The remaining 10% are associated with hot spots. These are areas when extra hot mantle material, in what is called a mantle plume, wells up and melts beneath the crust.

hot spots begin at the boundary between the mantle and the outercore.

No. Hot spots are not associated with plate boundaries.
Hot spots originate in the mantle, well below the Earth's surface.

A hot spot. An example of a hot spot are the islands in Hawaii which were made from hot spots.
volcanoes in Hawaii are formed by hot spots hot spots are areas of constant volcano activity. They are derived from unusually hot areas in the mantle. The overlapping mantle forms plumes of magma that rise and form volcanoes. source: http://visearth.ucsd.edu/VisE_Int/platetectonics/hot_spot.html
