Question

in this illustration, which site shows a subducting plate? a b c d

Explanation:

To determine which site shows a subducting plate, we recall that subduction occurs when one tectonic plate moves under another and is forced into the mantle. Looking at the illustrations:

• Site A shows a mid - ocean ridge (divergent boundary, plates moving apart).
• Site B also appears to be related to divergent or volcanic activity at a ridge.
• Site C shows one plate (oceanic, likely) moving under another (continental), which is the subduction process.
• Site D shows a different type of geological feature, not subduction.

Answer:

C. Site C
