Q. Fishing grounds are concentrated in the high latitudes. The reasons are:
1. great length of indented coastline
2. extensive continental shelves
3. water temperatures lower than 20°C
4. sparse population
✅ Correct Answer: (A)
1, 2 and 3
Explanation:
Fishing grounds are concentrated in high latitudes because of:
- Great length of indented coastline — creates many bays and estuaries rich in nutrients.
- Extensive continental shelves — shallow areas with abundant marine life.
- Water temperatures lower than 20°C — cooler waters are rich in oxygen and nutrients, supporting fish populations.
Sparse population (point 4) is not a direct factor affecting fishing grounds.
So, the correct reasons are 1, 2, and 3 — option (A).
