EXERCISE 17.7 Erosional Processes and Shoreline Landforms Name: Aliyana Campbell Section: Course: Date: 11/26/24 Refer to the photos specified to answer the following questions. (a) How did the large blocks in Figure 17.11a get into the breaker zone? What is their eventual fate? The water eroded at the lower levels of the plateau. Eventually, this plateau will collapse into the ocean (it will probably take decades and even earthquakes to help). (b) How did Morro Rock (Fig. 17.14b) become isolated from the bedrock shoreline? It was most likely the result of a sea arch collapsing and leaving Morro Rock as a sea stack. (c) What is the eventual fate of the sea arch in Figure 17.11c? The sea arch will eventually collapse and leave a pillar jutting out of the ocean. Examine the shoreline in FIGURE 17.15. Point Sur and False Sur are the same kind of feature and record the multistage development of this part of the California shoreline. (d) Given its size and steepness, is Point Sur made of resistant bedrock like granite or a softer rock like limestone? Explain. Limestone It doesn't seem very steep—at least, not as steep as the rest of the shore. (e) What material or type of material is the area between the Point Sur lighthouse and the California Sea Otter Game Refuge probably made of? Explain your reasoning. eroded limestone
