Marine Geography Quiz

Question 1A vessel travels 75 nautical miles. Use 1 nautical mile = 1.852 km to convert the distance to km, rounded to two decimal places.

Enter a number in km.

Answers within 0.005 km of the expected value are accepted.

Question 2Two instruments share a latitude and longitude but lie at different depths. What information is still needed to compare their environments?

The surface habitat classification applied through the water columnA single surface temperature assigned to both instrumentsThe depths and water properties at the two measurement sitesThe assumption that matching map points mean matching habitats

Question 3Floating material travels far from where it entered the sea. Which process connects the release and arrival sites?

A transport process driven by seawater circulationA change in seabed age beneath the arrival siteA legal transfer of ownership at each maritime boundaryA fixed habitat outline on a printed map

Question 4A coast retreats after its sediment supply declines. Which account treats the shoreline as a process?

The coast has reached a permanent geological endpointRemoval exceeds replacement under the changed conditionsSediment supply matters during deposition but not erosionThe mapped shoreline fixes where the water must stop

Question 5The habitat map marks a nursery ground. Which account explains a process sustaining the ecosystem?

Conditions stay uniform throughout the area assigned one habitat colorAnimals remain inside the mapped boundary throughout their livesNutrients and organisms pass between the nursery and nearby watersA larger shaded area supplies proportionally more food to each animal

Question 6A coastal state exercises resource rights in its exclusive economic zone. Which distinction matters?

Foreign navigation ends at the EEZ boundaryResource jurisdiction differs from full territorial sovereigntyAn EEZ grants ownership of migrating fish wherever they travelAn EEZ makes the water equivalent to the state’s land territory

Question 7A spill crosses from one jurisdiction’s waters into another’s. What does the crossing show?

Boundary markers redirect dissolved pollutants offshorePhysical transport does not stop at a legal boundaryA moving spill cancels the neighboring state’s authorityThe spill proves that marine regulation has no function

Question 8One satellite image shows a large bloom on one date. What evidence tests whether it is typical?

The persistent conditions revealed by the brightest patchA larger print of the same dated imageThe usual bloom duration indicated by the photograph’s sharpnessThe usual conditions revealed by observations across seasons

Question 9Nutrient enrichment is followed by heavy decomposition and low oxygen. Which mechanism explains the depleted water?

Respiration uses oxygen faster than mixing replenishes itNutrients convert dissolved oxygen into saltGreater algal production prevents biological decompositionLow oxygen is a direct measure of the ocean’s depth

Question 10Two shipping paths have similar lengths, but one crosses shallow water with frequent queues. Which comparison best supports route planning?

Rank vessel capacity by how straight each path looks on the mapCalculate travel time using straight-line separation of the portsAssign equal operating costs to routes of matching lengthCompare navigable depth and expected waiting and operating costs
