in your answers. Please use Google Earth to answer the following questions.
1.
Go to Point Sur, California.
What type of feature is Point Sur? Explain its genesis. (6 points)
Point Sur is a headland. Its genesis is due to the geological processes involving the lifting of
rocks and erosion for the sea over many years.

points)
There is a great accumulation of sand on the southern.
Which direction are the prevailing waves coming from? (4 points)

2.
Go to Penny Island, CA. This is where the Russian River meets the Pacific.
Was the tide high or low when this image was captured? Why do you think so? (4 points)
It seems that the tide is low in this image. This could be the result of the time of day, whatever
phase the moon was in, or other local factors.
3.
Go to Santa Cruz, CA.
Look at the agriculture fields to the west of town. What type of feature are these naturally
level fields? (4 points)
The fields to the west of town are likely alluvial plains, created by the depositing of sediment.
Go to the east of the Santa Cruz boardwalk and find the harbor entrance in Twin Lakes.
Which direction is the littoral current flowing? How can you tell? (4 points)
It seems that the littoral current is flowing parallel to the shoreline. One can tell that the current
is parallel by looking at the wave crests and how they are presented in relation to the coast.
4.
Go to Haystack Rock, Oregon. What type of feature is this? (4 points)
Haystack Rock is a sea stack, consisting of steep column of rock near the coast. These features
form through erosion and weathering.
