Why do some mountain ranges experience the rain shadow effect in terms of energy and kinetic energy?
A
The kinetic energy of the wind increases as it descends the leeward side, causing more rain.
B
The mountains absorb all the moisture, preventing any rain on the leeward side.
C
Moist air rises over the mountains, cools, and loses kinetic energy, causing precipitation on the windward side.
D
The sun's energy is blocked by the mountains, leading to dry conditions on both sides.
Verified step by step guidance1
Understand the concept of the rain shadow effect: It occurs when moist air ascends a mountain range, cools, and loses moisture as precipitation on the windward side, leaving the leeward side dry.
Recognize the role of energy: As moist air rises, it expands and cools due to the decrease in atmospheric pressure, which is a process that involves the conversion of thermal energy into potential energy.
Identify the change in kinetic energy: As the air rises, its kinetic energy decreases because the air molecules slow down due to cooling, leading to condensation and precipitation.
Explain the cooling process: The cooling of air is a result of adiabatic expansion, where the air loses heat energy without exchanging heat with the surroundings, causing water vapor to condense into rain.
Clarify the leeward side conditions: After losing moisture, the air descends on the leeward side, warming up and increasing in kinetic energy, but it remains dry because it has already lost its moisture content.
