OCE chap 11 Questions with Correct Answers (Grade A+)
Question 1: Under the protection of the Law of the Sea Treaty, a coastal nation has the right to
________ restrict the passage of vessels through a territorial sea exploit deep-ocean minerals at will in
international waters mine the continental shelf of a nation that has not ratified the Law of the Sea
extract oil at will within the jurisdiction of their Exclusive Economic Zone (EEZ) catch fishery species
within the boundaries of a neighboring nation's EEZ
Answer: extract oil at will within the jurisdiction of their Exclusive Economic Zone (EEZ)
Question 2: The international Law of the Sea Treaty _________ provides for arbitration of disputes
puts no restrictions on the mining of seabed minerals in areas of the ocean beyond any nation's
exclusive economic zone allows nations to prohibit the transit of unfriendly warships through straits
adjacent to their shorelines establishes an exclusive economic zone (EEZ) that extends 12 nautical miles
seaward from the coast of each maritime nation regulates the dumping of waste in international waters
Answer: Provides for arbitration of disputes
Question 3: At the mouth of the Amazon River in Brazil, how would the coastal waters be characterized
with respect to temperature and salinity? A strong halocline and a strong thermocline are present.
isothermal with a strong halocline isohaline with a strong thermocline isohaline and isothermal
isohaline and a strong halocline
Answer: isothermal with a strong halocline
Question 4: An isothermal temperature profile from surface to seafloor may exist in coastal ocean
water ___________ in high-latitude waters only in either low-latitude waters or high-latitude waters in
mid-latitude waters during summer near mid-latitude river mouths in winter in low-latitude waters
only
Answer: in either low-latitude water or high-latitude waters
Question 5: MA: Of the following statements about the physical characteristics of coastal oceans, which
is/are true? (4) In low-latitude areas where there is no mixing, surface water temperatures can be very
high. In high-latitude areas, the coastal ocean is isothermal (has a uniformly low temperature from
surface to deeper waters). In middle-latitude coastal oceans where evaporation is high, a halocline can
develop. Most coastal waters have very high salinity due to freshwater runoff. Because of onshore wind
and coastal runoff, geostrophic currents along western North America flow northward.
Answer: all except: most coastal waters have very high salinity due to freshwater runoff
Question 6: T/F: The mediterranean Sea water has little impact on the waters of the Atlantic ocean
Answer: false

, Question 7: Lagoons that form behind barrier islands are examples of: bar-built estuaries. salt wedge
estuaries. coastal plain estuaries. fjords. tectonic estuaries.
Answer: bar-built estuaries
Question 8: An estuary produced by faulting or folding of rocks that creates a dropped-down section
into which a river flows is called a: bar-built estuary. salt wedge estuary. fjord. tectonic estuary. coastal
plain estuary.
Answer: tectonic estuary
Question 9: Estuarine circulation associated with a deep, high river volume system where no horizontal
salinity gradient exists at the surface bar-built estuary. salt wedge estuary. vertically mixed estuary.
slightly stratified estuary. highly stratified estuary.
Answer: salt wedge estuary
Question 10: When less saline water enters a marginal sea above a return flow of saltier water, the
circulation is called: fjord circulation. loop current circulation. lagoon circulation. estuarine
circulation. Mediterranean circulation.
Answer: Mediterranean circulation
Question 11: Water in the eastern parts of Chesapeake Bay tends to be more saline than water farther
west because _____________ the prevailing westerly wind pushes the seawater to the eastern shore
ocean water entering the bay hugs the eastern shore because of the Coriolis effect the bay is deeper
toward the eastern side more freshwater tributaries flow in from the western shore the eastern part of
the bay experiences a higher evaporation rate
Answer: ocean water entering the bay hugs the eastern shore because of the Coriolis effect
Question 12: MA: Of the following statements about the Mediterranean Sea, which is/are true? (5) The
Mediterranean Sea is one of the few inland seas in the world that is underlain by oceanic crust. The
Mediterranean Sea is actually a number of smaller seas connected by narrow necks of water into one
larger sea. The warm, salty, and dense Mediterranean Intermediate Water flows out as a subsurface
flow over the Gibraltar Sill and into the Atlantic Ocean. Evaporation in the arid eastern part of the
Mediterranean Sea causes an inward surface flow at the Strait of Gibraltar. Thick salt deposits on the
floor of the Mediterranean Sea suggest that it completely dried up about 6 million years ago.
