Question

1. choose the best answer.

which of these causes a chain of volcanic islands like the hawaiian islands to form over time?
older volcanic islands sinking below sea level
earthquakes along ocean trenches
movement of tectonic plates over a hot spot
a single massive volcanic eruption

Explanation:

The Hawaiian Islands are formed due to the movement of tectonic plates over a hot spot. A hot spot is a region in the Earth's mantle where magma is particularly hot and rises to the surface. As the tectonic plate moves over the stationary hot spot, a chain of volcanic islands is formed. Each new island forms as the plate moves, and the older islands move away from the hot spot.

Answer:

movement of tectonic plates over a hot spot
