An Assertion-Reason question requires evaluating both statements independently for truth, and then determining whether the Reason correctly explains the Assertion. Here, the Assertion concerns Earth's surface relief resulting from differential rates of geomorphic processes, and the Reason concerns lithological/structural variation in crustal rocks causing differential resistance to those processes.
Assertion (A): Earth's surface possesses relief largely because geomorphic processes (weathering, erosion, deposition) operate at differential rates across different areas — this is a true,...
