GENERAL GEOLOGY

Detailed explanation-1: -Every time there’s a merger, the order number changes. (For example, if a second-order stream joined a third-order stream, the result would be a fifth-order stream.)

Detailed explanation-2: -When two second-order streams come together, they form a third-order stream.

Detailed explanation-3: -The stream order increases when streams of the same order intersect. Therefore, the intersection of two first-order links will create a second-order link, the intersection of two second-order links will create a third-order link, and so on.

Detailed explanation-4: -When two streams with the same order join, the resulting stream has the next highest order than the joining streams. For example, when two second order streams join, the resulting stream is third order. A stream may separate and then converge-this is called a ‘braided stream’.
