Description: Type 195348.36 N 1553458.11 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")

step 1 differential equation. First, let's get a disapurable equations first. We have D -Y over Y equal

Key Concepts

Flux Melting

Flux melting is the process through which the addition of volatiles such as water lowers the melting temperature (solidus) of mantle rocks. In tectonic settings like subduction zones, water released from the subducting slab enters the overlying mantle, reducing the solidus temperature and initiating partial melting even at lower temperatures than would be possible by temperature increase alone.

Subduction Zone Processes

Subduction zones, where one tectonic plate is forced beneath another, are key settings for magma generation. As the subducting slab undergoes dehydration, water is liberated into the mantle wedge, triggering flux melting. This process is critical in forming magmas that create volcanic island arcs and continental volcanic features.
