Question

Difficulty: HardPhysical Geography of the World

Arrange the following oceanic trenches in sequence from North to South latitude:

  1. 1Aleutian Trench
  2. 2Puerto Rico Trench
  3. 3Sunda (Java) Trench
  4. 4South Sandwich Trench

Answer

The correct order from North to South latitude is: Aleutian Trench (52∘N52^\circ\text{N}), Puerto Rico Trench (19∘N19^\circ\text{N}), Sunda (Java) Trench (10∘S10^\circ\text{S}), and South Sandwich Trench (55∘S55^\circ\text{S}).
The correct spatial ordering from North to South follows descending latitude: the Aleutian Trench is in the northern sub-polar Pacific at 52∘N52^\circ\text{N}, followed by the Puerto Rico Trench in the tropical Atlantic at 19∘N19^\circ\text{N}, the Sunda (Java) Trench south of Sumatra/Java in the Indian Ocean at 10∘S10^\circ\text{S}, and finally the South Sandwich Trench in the southern Atlantic near the Antarctic Circle at 55∘S55^\circ\text{S}.

Step-by-Step Solution

1
Identify the geographical coordinates and hemispheric positions for each given trench.
Aleutian Trench is sub-polar North Pacific (52∘N52^\circ\text{N}), Puerto Rico Trench is tropical North Atlantic (19∘N19^\circ\text{N}), Sunda Trench is tropical Southern Indian Ocean (10∘S10^\circ\text{S}), and South Sandwich Trench is sub-Antarctic South Atlantic (55∘S55^\circ\text{S}).
Establishing accurate latitudinal coordinates is essential to sequence features from North to South.
2
Sort the features starting from the highest northern latitude down across the equator to the highest southern latitude.
The progression moves from 52∘N→19∘N→10∘S→55∘S52^\circ\text{N} \rightarrow 19^\circ\text{N} \rightarrow 10^\circ\text{S} \rightarrow 55^\circ\text{S}.
North to South sequence requires descending order of latitude values.
3
Map the sorted latitudinal positions back to the item identifiers.
Aleutian Trench (item_1) →\rightarrow Puerto Rico Trench (item_2) →\rightarrow Sunda Trench (item_3) →\rightarrow South Sandwich Trench (item_4).
Verifies that the resulting order matches the spatial arrangement requested.
