Final answer:
The port of Fontvielle is growing in size due to land reclamation from the sea, allowing for the expansion of port facilities and accommodating oceangoing vessels.
Step-by-step explanation:
The port of Fontvielle is growing in size due to land reclamation from the sea. Reclamation is the process of creating new land by filling in water bodies with soil, rocks, or other materials. This allows for the expansion of port facilities and the development of new infrastructure to accommodate oceangoing vessels.
The growth of ports is often driven by the need to handle increased trade and industry, and those with quality site factors, like good port facilities, tend to attract more growth.
