The flow chart shows the formation of one type of desert, known as a rain-shadow desert. In general, this intricate procedure can be broken down into two main stages: commencing with winds going upwards and culminating in this type of desert being formed. Notably, it is a natural process that does not require human intervention. Another noteworthy feature has to be the fact that winds cross thousands of kilometers before contributing to the formation of the rain-shadow desert.
The process begins when winds come from a sea to a mountain in a coast, after which they are pushed upwards. It can be noted that, while climbing up, moist air rises and cools, while also passing through the windward side of the mountain, all of which enable clouds to form. Rain falls can be observed afterwards, preceding the further movement of air.
Having gone upwards, dry air continues over the mountain to reach a leeward side. Once this happens, dry winds keep moving downwards, approaching inland areas and thereby allowing for the formation of rain-shadow deserts.
