What is the role of slope in a parallel drainage pattern?
Answer and explanation
Correct answer: A steep and nearly uniform slope guides streams to flow in almost the same direction
A parallel drainage pattern usually develops on a steep, nearly uniform slope. Under this relief, several streams flow downslope in almost the same direction and therefore appear parallel. Option B describes conditions more likely to produce irregular drainage, while C and D describe radial and centripetal patterns respectively. Exam tip: identify drainage patterns by linking the direction of slope with the landform.
