← GeographyWhich boundary change results when thermal expansion weakens subtropical gyre stream flows?
A)The gyre shrinks towards equator✓
B)Circumpolar current strengthens significantly
C)Oceanic freshwater lens formation expands
D)The gyre intensifies westward rapidly
💡 Explanation
Weakened stream flows leads to shrinking gyres; due to thermal expansion reducing density gradients, diminishing the pressure gradient force which drives the gyre flows, rather than a strengthening gyre which requires the opposite change.
