What is the main difference between antecedent and superimposed drainage?
Answer and explanation
Correct answer: An antecedent river maintains its course during uplift, whereas a superimposed river carries an inherited course from an upper cover onto underlying rocks
An antecedent stream existed before tectonic uplift and eroded downward rapidly enough to preserve its course across the rising structure. A superimposed stream first developed on a relatively uniform cover of younger rocks; after erosion removed that cover, its inherited course continued across older structures below. Therefore A states the essential contrast; B, C, and D are false generalisations.
