Type 19 53 48.36 N 155 34 58.11 W in the search bar on Google Earth, and zoom out to an eye altitude of ~615 miles. The magma that resulted in the formation of these islands was generated by what process?a. decreased pressure (arrow "b") b. the addition of water (arrow "d", which shifts the solidus to the left) c. increased temperature (arrow "a")

Option C = increased temperature (arrow "a").

Explanation:

Magma is used by people studying geography or scientists at large to describe the molten substance(which is very hot) which can be found under the ground.

From the question above we see that there is something(a map) to see on the search engine that is "19 53 48.36 N 155 34 58.11 W".

The result for the search brought a map and there is need to zoom it out to zoom out to an eye altitude of approximately 615 miles.

The magma seen here is as a result of changes in Temperature which is actually increase in temperature which in turn forms the island. This one of the ways in which islands are formed.
