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.
Convergent boundaries that involve at least one oceanic plate form subduct â¦ ion zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form. At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma. Transform boundaries have no such means of producing magma.
