← GeographyWhich geographic feature limits orographic precipitation on the leeward side of the Andes mountains during strong prevailing winds?
A)Rain shadow formation✓
B)Glacial subsidence
C)El Niño oscillation
D)Thermal inversion layers
💡 Explanation
When moisture-laden air rises over the Andes mountains, adiabatic cooling causes condensation and precipitation, but the descending air on the leeward side is dry, creating a rain shadow because of the moisture deficit. Therefore rain shadow formation results, rather than other proposed atmospheric effects, under similar conditions.
