Difficulty: MediumPhysical Geography of the World

Deep oceanic trenches are prominent relief features of the ocean floor formed along convergent plate margins. Arrange the following oceanic trenches in sequential order from North to South based on their geographical latitude:

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

Answer

The correct sequence from North to South is: Aleutian Trench (approx. 52° N) → Mariana Trench (approx. 11° N) → Java (Sunda) Trench (approx. 10° S) → South Sandwich Trench (approx. 55° S).
The correct order arranges the trenches from northernmost latitude to southernmost latitude: Aleutian Trench (~52° N) in the sub-polar North Pacific, Mariana Trench (~11° N) in the tropical North Pacific, Java Trench (~10° S) in the equatorial South Indian Ocean, and South Sandwich Trench (~55° S) in the sub-antarctic South Atlantic Ocean.

Step-by-Step Solution

1
Identify the geographical latitude for each oceanic trench
Aleutian Trench is near 52° N; Mariana Trench is near 11° N; Java Trench is near 10° S; South Sandwich Trench is near 55° S.
Establishing exact or approximate latitudinal positions is necessary to determine northernmost to southernmost sequence.
2
Sort the latitudinal values descending from Northern Hemisphere to Southern Hemisphere
52° N > 11° N > 10° S > 55° S.
Ordering from North to South requires arranging positive latitudes down to higher negative (southern) latitudes.
3
Match the sorted latitudes back to the corresponding oceanic trench items
Aleutian Trench (1st) → Mariana Trench (2nd) → Java Trench (3rd) → South Sandwich Trench (4th).
Verifies the final order against the provided item list.

Key Concept

Spatial arrangement and latitudinal distribution of major ocean floor relief features and trenches across global oceans.
