Final answer:

The stream drainage pattern associated with faulting is rectangular, forming as streams follow fractures and faults in the landscape. This produces a drainage network with distinct right angles, reflecting the underlying geological structures.

Step-by-step explanation:

The stream drainage pattern associated with faulting is typically rectangular. This pattern forms as streams follow the pattern of fractures and faults that occur due to various tectonic processes. In geological regions characterized by extensive faulting, streams tend to course along fractures due to the easier path provided by these pre-existing weaknesses in the rocks. As a result of this following, the drainage pattern exhibits a lot of right-angled turns and a rectilinear network, which is indicative of the underlying structural control influenced by the faults and fractures.

Faults come in different types like normal, reverse, strike-slip, and thrust faults, each affecting the landscape in distinctive ways. Understanding the specific type of faulting helps in interpreting the geological history and the associated drainage patterns on the surface of the Earth. For instance, in an area with a dominant strike-slip fault, streams might show sharp bends reflecting lateral movement along the fault plane.
