Question
1. At the end of the summer season, which would you expect to see at a typical beach:
[Much more sand piled up on the beach relative to the end of the winter season]
[Much less sand piled up on the beach relative to the end of the winter season]
[The same amount of sand should be at the beach no matter what season it is]
2. Where does the sand on our beaches in California primarily originate from?
[Granites of the Sierra-Nevada mountains] [Longshore current] [Streams] [Turbidity currents]
3. How does this sand travel from its origin to a California beach?
[Granites of the Sierra-Nevada mountains] [Longshore current] [Streams] [Turbidity currents]
4. Turbulent water currents that flow within the surf zone parallel to the shoreline are called?
[Turbidity currents] [Longshore current] [Longshore transport] [Upwelling]
5. Sand that is carried by turbulent water currents that flow within the surf zone parallel to the shoreline are called?
[Turbidity currents] [Longshore current] [Longshore transport] [Upwelling]
6. According to the lecture, what is the best definition of a spit from the choices given below?
[A spit is an elongated ridge of sand extending from a headland into the mouth of an existing bay]
[A spit is sand that extends out from a harbor that has to be dredged regularly]
[A spit is sand that has been deposited by the longshore current]
[A spit is defined as low-energy waves that travel parallel to the shoreline]
7. What transports the sand to the location the spit is created in?
[Turbidity currents] [Longshore current] [Upwelling] [Downwelling]
8. What happens to allow sand to be deposited and create the spit?
[Energy increases within the longshore current.]
[Energy decreases within the longshore current.]
[Energy stays the same within the longshore current.]
9. A stretch of coastline with no sand at any time of the year most likely has:
[High energy waves hitting it all year long.]
[Low energy waves hitting it all year long.]
[No waves are hitting that coastline at all.]
Explanation / Answer
1. Much more sand piled up on the beach relative to the end of the winter season.
Summer waves are long and shallo, they deposit or pileup sand on the beach.
