Give a geographical reason for each of the following:

The windward sides of mountains receive more rainfall than the leeward sides.

The windward sides of mountains receive more rainfall than the leeward sides because the sudden ascent of warm moist air on the windward sides causes cooling of air, leading to condensation and precipitation.
On the contrary, on descending the leeward slope, a decrease in altitude increases both the pressure and the temperature, leading the air to get compressed and warm. Consequently, the relative humidity drops and there is evaporation and little or no precipitation in the rain shadow area.
