The accompanying block diagram shows the bedrock age as measured by radioactive dating and the present location of part of the Hawaiian Island chain. These volcanic islands may have formed as the Pacific Plate moved over a mantle hot spot. This diagram provides evidence that the Pacific Crustal Plate was moving toward the

The map shows the island of Hawaii (approximately 20° N 157° W) and the locations of recent volcanic eruptions and earthquake epicenters. The volcanic eruptions are inferred to be caused by the movement of the lithospheric plate over a hot spot in the mantle below.

Which inference concerning the distribution of earthquakes and recent volcanic eruptions on this island is most accurate?

• Earthquakes and recent volcanic eruptions are located mainly along the boundary between the older rocks and the younger rocks.

• Recent volcanic eruptions are more common than earthquakes.

• Many earthquakes occur near recent volcanic eruptions.

• Earthquakes and recent volcanic eruptions rarely occur in the same areas.

The Hawaiian Islands were formed as a result of

• lava flowing over Earth's surface where two tectonic plates move apart

• an oceanic plate moving over a mantle hot spot

• two oceanic plates colliding to form an island arc

• tectonic plates sliding past each other

The diagram below shows the collision of an oceanic plate and a continental plate.

Collisions between oceanic plates and continental plates are thought to result primarily from

• hot liquid magma in the inner core

• convection currents in the mantle

• volcanic eruptions along coastlines

• meteor impacts in the ocean basins

The basaltic bedrock of the oceanic crust is classified as

• felsic, with a density of 2.7 g/cm³

• felsic, with a density of 3.0 g/cm³

• mafic, with a density of 2.7 g/cm³

• mafic, with a density of 3.0 g/cm³

The map below shows some tectonic plate boundaries near South America and Africa. Letters A, B, C, and D represent locations on Earth's surface.

Which location most likely has the youngest bedrock?
