Refer to Figure 12.1 and select the letter that identifies each of the following.

wave crest wavelength

wave trough wave base

wave height

At what water depth will the wave described in Question 7 begin to break? m

At what water depth will a deep-water wave with a wavelength of 46 meters begin to "feel bottom"? ______ m.

For the following exercises, match the given function of best fit with the appropriate scatterplot in Figure 7 through Figure 11. Answer using the letter beneath the matching graph.

$$y=10.209 e^{-0.294 x}$$

At approximately what water depth ($10, 20, 30,\ or\ 40\ feet$) will the approaching waves begin to touch bottom and slow down? Water depth: ______ feet

At approximately what water depth-3, 6, 12, or 24 feet-will the waves begin to break? ft

Use the descriptions of shoreline features provided above to label the structures in Figures 12.5 and 12.6. The same feature may appear more than once.

Label a marine terrace, a wave-cut cliff, and a wave-cut platform in Figure 12.7.

Next to each of the features listed below, indicate whether it is the result of erosional or depostional processes. Sea stack: __________________________________ Wave-cut cliff: ______________________________ Spit: ______________________________________ Barrier island: ______________________________ Baymouth bar: _____________________________ Marine terrace: _____________________________

Label a baymouth bar and a spit in Figure 12.8.

Using Figure 8.5C as a reference, identify the type of feature found at each of the following letters on the map in Figure 8.10:

Letter C (Old River):

Letter D:

Letter E:
