In addition, sea level rise poses a threat to barrier islands with communities and vulnerable habitats. 5. Refer to Figure 16.5. Ia. During Stage 1, why would sea level be lowest compared to the other stages? b. During Stage 2, what might explain the flooding from river valleys upstream? c. During Stage 3, what would cause the land to be broken into spits? (Tip: refer to Figure 16.6, which shows a sand spit).
