The Hаwаiiаn hоtspоt chain оf islands and seamounts is highest at the young end of the chain. From the young end toward the old end of the chain, the elevation of the islands drops toward sea level. Once they are below sea level (seamounts), the pattern continues as the older ones are gradually deeper underwater. This is illustrated in Figure 4-24. Give two (2) reasons why the older islands and seamounts are lower or deeper than the younger ones.
