Gulf
Which sea, gulf, or bay is almost completely enclosed by land, but connected to the Atlantic Ocean
via the Strait of Gibraltar? ✔Correct Answer-Mediterranean Sea
Which sea, gulf, or bay is surrounded by China, Vietnam, Malaysia, and the Philippines? ✔Correct
Answer-South China Sea
The Gulf of Mexico was formed by... ✔Correct Answer-Techtonic activity
T/F: Since the end of the Gulf of Mexico seafloor spreading about 94 Ma, the location of the
shoreline of the Gulf has not changed. ✔Correct Answer-False
How do we determine the movement of plates and the rates of sea floor spreading? ✔Correct
Answer-Dating magnetic stripes of rock on the sea bed and measuring the distance from the ridge
crest
Match the following facts to the most appropriate sub-field of oceanography... shallow, tropical seas
promote growth of shelled organisms such as coral, clams, and certain types of plankton ✔Correct
Answer-Biological oceanography
Match the following facts to the most appropriate sub-field of oceanography... calcium is a nutrient
and it also helps the soil maintain moisture balance and the correct salinity and acidity ✔Correct
Answer-Chemical oceanography
Match the following facts to the most appropriate sub-field of oceanography... calcium carbonate
shells accumulate on the sea floor, and over time produce sediments that are rich in calcium
✔Correct Answer-Geological oceanography
Match the following facts to the most appropriate sub-field of oceanography... during the Cretaceous
period, the Earth was much warmer and there was no ice covering the poles, which resulted in a high
sea level and shorelines that extended much further inland than they do today ✔Correct Answer-
Physical oceanography
Your classmate states that they can't focus on geology, because it all happened so long ago and the
geological history of the Gulf of Mexico is not relevant to recent human history or to modern human
society and culture. What is one example you would give to demonstrate their way of thinking is
flawed? (more than one answer may be at least partially correct, but please choose the response
, that addresses your classmate's argument the best and reflects what we have learned in class)
✔Correct Answer-The "Black Belt", which is a highly productive region of the United States, is a
consequence of the unique origin story of the Gulf of Mexico and has been associated with historical
and modern racial dynamics in the country
The following events describe parts of the history of the formation of the Chesapeake Bay. Sort the
events in geological time...
- rising sea levels flood the river valley
- a meteor collides with the Earth and forms a crater
- rivers carve a deep canyon during a low stage in sea level
- river valleys converge to form one massive river valley ✔Correct Answer-1. a meteor collides with
the Earth and forms a crater
2. river valleys converge to form one massive river valley
3. rivers carve a deep canyon during a low stage in sea level
4. rising sea levels flood the river valley
The following events describe parts of the birth of an ocean. Sort the events in geological time...
- crust begins to pull apart, and faults occur in the crust forming a rift valley
- the inlet widens and stabilizes, maintaining an opening for seawater flow, and sediments
accumulate
- a hot spot develops underneath the continental lithosphere
- a new ocean basin opens up enough to allow seawater to enter with periods opening and closing of
the basin ✔Correct Answer-1. a hot spot develops underneath the continental lithosphere
2. crust begins to pull apart, and faults occur in the crust forming a rift valley
3. a new ocean basin opens up enough to allow seawater to enter with periods opening and closing
of the basin
4. the inlet widens and stabilizes, maintaining an opening for seawater flow, and sediments
accumulate
A strong oceanic current flowing northward along the eastern coast of Florida ✔Correct Answer-
Florida current
A western boundary current that begins offshore of Cape Hatteras and flows past eastern Canada
✔Correct Answer-Gulf Stream
A current in the Gulf of Mexico that bulges northward and forms eddies ✔Correct Answer-Loop
current
A continuation of the flow of warm water northeast towards Europe ✔Correct Answer-North
Atlantic Current
T/F: Major wind-driven boundary currents in the western Gulf of Mexico move water in a clockwise
(anticyclonic) direction ✔Correct Answer-True
Which of the following is true about eddies...
- they are relatively rare, formed only by the Loop Current in the Gulf
- eddies can act as "island oases", because they are the site of intense biological production
- the cyclonic motion of eddies can lead to tropical cyclone formation
- due to the Coriolis Effect, eddies always move in a clockwise or anticyclonic direction ✔Correct
Answer-Eddies can act as "island oases", because they are the site of intense biological production
