Final answer:
Wave energy development is most optimal along sandy shores in the Northern Hemisphere because waves carrying energy are compressed into higher waves as they reach shallow waters near sandy shores.
Step-by-step explanation:
The conditions for the development of wave energy are most optimal along Sandy, Northern shores in the Southern Hemisphere.
Waves carry a significant amount of energy, and as they reach the shallow waters near sandy shores, their energy is compressed into a smaller volume, creating higher waves. This makes sandy shores in the Northern Hemisphere the ideal location for wave energy development.
