The rain water is the purest form of water available in nature, because it is formed by the process which we generally know as Distillation. Rain water is not necessarily all that pure as it can contain atmospheric contaminants, but it contains very little salt, and hence is regarded as "fresh" water as opposed to salt water.

How does carbon dioxide form natural rainwater features?
Carbon dioxide in the atmosphere dissolves in rainwater to form carbonic acid, which is a weak acid. Over time, carbonic acid can react with minerals in rocks, causing weathering and erosion. This process contributes to the formation of natural rainwater features such as caves, sinkholes, and karst landscapes.
