Final answer:
The Phoenicians relied on the sea for travel and trade primarily due to the lack of viable land routes in their region, which made maritime navigation essential.
Step-by-step explanation:
The Phoenicians relied on the sea to get home primarily due to c) Lack of land routes in their region. Their civilization was centered on the coast of the Mediterranean and they established numerous colonies across the sea. Trade and travel by sea were essential because overland routes were either limited or presented numerous challenges.
Unlike other ancient civilizations that might have had access to vast river systems or fertile plains, the Phoenicians capitalized on their maritime skills. They became excellent sailors, explorers, and traders, and their settlements often served as vital trade hubs connecting a wide range of regions and resources. Their ships not only facilitated the movement of goods but also the spread of their cultural and technological innovations, such as the Phoenician alphabet. Over time, Carthage, initially a colony, rose to prominence as a powerful Phoenician city due to its strategic location for controlling trade in the western Mediterranean.
Why did the Phoenicians rely on the sea to get home?" is c) Lack of land routes in their region.
