← GeographyWhich mechanism influences stream displacement when high pressure systems stagnate over mountainous regions?
A)Orographic lift induces precipitation shifts✓
B)Adiabatic cooling stabilizes upper atmosphere
C)Coriolis effect deflects upper-level airflow
D)Radiative forcing elevates regional temperatures
💡 Explanation
When high pressure stagnates, orographic lift affects moisture because air is forced upward by mountains, enhancing precipitation on the windward side which shifts stream flow from leeward effects. Therefore, the increased windward precipitation and erosion induces displacement, rather than atmospheric stabilization, coriolis deflection, or direct radiative heating.
