Answers:
The entire passage is correct, only the words "windward" and "leeward" should be interchanged.
The inaccurate statements are-
(a) The warm and moist air rising up the mountain on its leeward side
(b) The cool and dry air moves towards the other side of the mountain where the desert lies and is the windward side
Explanation:
In order to form a rain shadow effect, the warm and moisture containing air rises up the mountain on its windward side. The water in this high region gets condensed and starts precipitating in the form of rain or snow.
After precipitation, the air becomes dry and warm and moves towards the leeward side where there is the desert. The leeward side does not receive any rainfall and this rain shadow zone is mainly the reason behind the dryness and the extreme climates in the deserts.
The words that are underlined above are the wrong words in the given paragraph.
