  2. 2Salem (Steel manufacturing and textile processing hub)
  3. 3Tiruchirappalli (Heavy engineering and Cauvery basin agro-hub)
  4. 4Tirunelveli (Wind energy generation and agro-processing center)

Answer

The correct geographical sequence from North to South is Tiruvallur, followed by Salem, Tiruchirappalli, and Tirunelveli.
Tiruvallur is situated at the northern border of Tamil Nadu near Chennai. Moving southwards, Salem occupies the inland north-central region, followed by Tiruchirappalli in the central Cauvery delta basin, and finally Tirunelveli in the southern plain region.

Step-by-Step Solution

1
Identify the latitude and regional position of Tiruvallur
Tiruvallur borders Andhra Pradesh in northern Tamil Nadu (~13.1° N), placing it at the top of the sequence.
Establishing the northernmost boundary reference point.
2
Locate Salem relative to central and northern districts
Salem lies in the north-central interior plateau area (~11.6° N), south of Tiruvallur but north of the Cauvery delta.
Determining the second location in the north-south axis.
3
Identify Tiruchirappalli's position along the Cauvery basin
Tiruchirappalli is central (~10.7° N), positioned south of Salem and north of the southern plains.
Placing the central economic hub.
4
Confirm Tirunelveli's position in southern Tamil Nadu
Tirunelveli sits near the southern tip of the state (~8.7° N), completing the sequence.
Finalizing the southernmost element.
