What is it called when water forms to look like a root structure? I've tried looking it up on google but I can't find anything. I'm talking about when a small amount of water forms to look like a root hair structure, thin and branching out.
The term you are looking for is Dendritic, it literally means "having a branched form resembling a tree" and is used to describe the shape of rivers but can also apply to anything with that pattern.
