Which boundary change results when thermal expansion weakens subtropical gyre stream flows?

💡 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.
