#3218: Subduction Retrieval

XKCD comic, described below.
Transcript

[A large structure resembling a bridge has been positioned over the intersection of two tectonic plates, one under the ocean and one forming a jagged, mountainous coast, with one "foot" on each plate. A winch is hanging from the center of the bridge, connected to a chain which is hooked into the oceanic crust. The winch is pulling up the crust, causing it to fold and wrinkle. Cueball and Ponytail are standing on one large fold next to where the chain is hooked to the crust, and another Cueball is standing on the continental crust. Oceanic Cueball has his arms up. On a portion of subducted oceanic crust, far below the ground, a small shining lump is visible.]

PSA: Please stay out of the Pacific Ocean today. Someone lost their wedding ring in a subduction zone and USGS is pulling the plate back up to retrieve it.
