The Hawaiian Islands are formed on a region of intra plate volcanic activity on the Pacific plate. This region is known as a hot spot. Scientists are not exactly sure what causes this but they do know that a plume of magma rises through the mantle and forces it's way through the crust to form submarine volcanoes and over time volcanic islands.
The magma that rises here originates from the mantle and not crustal melt and so forms basic or basaltic lava.

Hi, I'm happy to help, what's the question you need help with?
Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
- P-waves are body waves that propagates within a body. They cause movement internally.
- Secondary waves are surface waves. They move on the surface of earth.
- One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
- Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.

Answer: So, if an oceanic tectonic plate collides with a continental plate, the denser oceanic plate is likely to sink beneath the continental plate, creating a subduction zone. If, however, two continental plates (therefore of similar density) smack into one another, they, instead, lift up against one another.
