In J.D. Salingerâs Catcher in the Rye, the novelâs troubled anti-hero, Holden Caulfield, gets into a strange discussion with a cab driver in New York City. Wondering what happens to the fish when a large pond in New Yorkâs Central Park freezes over for the winter, the agitated cabbie informs Holden that the fish freeze right along with the pond. When the ice melts, the fish thaw out and go on their way. Can fish and other aquatic creatures really survive in a state of suspended animation until spring?
Introduction. A divergent boundary is an area where two crustal plates are separating. Most of these tectonic plate boundaries are located on the floor of the oceans. The separating plates form rift valleys on the ocean floor where there are weaknesses in the crust. New oceanic crust. The weaknesses in the crust allow molten lava to move toward the Earth's surface on the ocean floors.
Divergent Boundaries Divergent boundaries are the zones where two tectonic plates are moving away from one another. Divergent boundaries are constructive boundaries because new crust is generated by magma pushing up from the mantle as the plates pull away from each other. Seafloor Spreading. Divergent boundaries in the middle of the oceans cause seafloor spreading.
