Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long, narrow tail that originates in the mantle. This type of volcanism, hot spot volcanism, is unique. Why?

A The hot spot volcanoes rarely result in mountain building; they are a destructive process.The hot spot volcanoes rarely result in mountain building; they are a destructive process.
B It does not occur at plate boundaries where most all other volcanism occurs.It does not occur at plate boundaries where most all other volcanism occurs.
C It occurs where two tectonic plates converge and is usually the site of mountain building.It occurs where two tectonic plates converge and is usually the site of mountain building.
D The resulting volcanoes always produce islands.
