In central AP, trace the Krishna river and delta: Nagarjunakonda toward the reservoir zone, Amaravati's stupa and Amareswara temple in the Guntur-side landscape, Vijayawada's Kanaka Durga shrine and urban river crossing, then the delta's coastal connections. Move north into the Godavari region for Annavaram, Draksharamam and Coringa. Their site types are different: archaeology, temple, temple, temple and mangrove sanctuary. A route planner may connect them, but an exam answer must preserve each identity.

The case study also teaches district-date discipline. Draksharamam appears in older East Godavari material yet is in present Konaseema; Coringa is near Kakinada and current administrative references should be checked. The Amaravati name can be ancient or modern. A river map can locate the broad zone but cannot prove archaeological dates, worship practices or legal protection. Pair geography with the correct official source: ASI for the stupa, district/temple sources for shrines and Forest Department for the sanctuary.

Worked example: Build a Krishna-Guntur-Godavari route from Amaravati's stupa and Amareswara distinction through Vijayawada, Annavaram, Draksharamam and Coringa. Say which items are temples, which are archaeology and which are ecology. The administrative districts differ by date; using only an old brochure's headings may make a current district answer wrong.

Active recall: Draw a Krishna-to-Godavari route and write one word beside each site: stupa, shrine or mangrove.
