What does the red in the picture represent?

The oldest crust where it is being destroyed.

The youngest crust that is being created.

The areas where two plates are converging.

The magnetic reversals of Earth's history.

What geologic feature formed the Hawaiian islands?

Volcanic island chain

Volcanic mountain chain

Hot spot

Mid-ocean ridge

What tectonic activity created Hawaii?

It is a subduction zone that makes volcanoes as the oceanic crust melts under another oceanic crust.

It is an area of sea-floor spreading that creates volcanoes as two plates diverge.

It is an area of transform boundaries; two plates are pushing past each other and creating volcanoes as they go.

It is a hot spot that originates from the core and stays still  as the plate moves over it creating volcanoes.
