Question

in this illustration, which site is mostly likely to form an island chain? a b c d

Explanation:

Island chains (like the Hawaiian - Emperor seamount chain) are often formed by hot - spot volcanism. In a hot - spot setting, as a tectonic plate moves over a stationary hot spot, a series of volcanoes are formed. Site B shows a situation where there is a hot - spot (the yellow area representing magma source) and the movement of the plate (indicated by the direction of the plate motion relative to the hot spot). As the plate moves, new volcanoes form over the hot spot while the older ones are carried away, creating a chain of islands or seamounts.

Answer:

B
