Sketch and label a cross-sectional view of the Mid-Atlantic Ridge. Explain how a cross section of the East Pacific Rise would look different. hypothesized that corals responded to the gradual change in water depth caused by the subsiding volcano by building the reef complex upward. Eventually, the volcano would submerge beneath the sea, and its remnant would be covered by a type of reef we call an atoll. During Darwin’s time, however, there was no plausible mechanism to account for how or why so many volcanic islands sink. The plate tectonics theory provides the most current scientific explanation of how volcanic islands become extinct and sink to great depths over long periods of time. Some volcanic islands form over relatively stationary mantle plumes, causing the lithosphere to be warmed and buoyantly uplifted. Over spans of millions of years, these volcanic islands gradually sink as the moving plates carry them away from the region of hot-spot volcanism because the lithosphere cools, becomes denser, and sinks (Figure 10.13). Volcanic islands that form on spreading centers also sink when they move away from these areas of upwelling. ▼ Figur
