Final answer:
The culture of the Phoenicians was different from other river civilizations as they focused on maritime trade and seafaring culture rather than agriculture.
Step-by-step explanation:
The culture of the Phoenicians differed from other river civilizations in their focus on maritime trade and seafaring culture.
Unlike other river civilizations that relied on rivers such as the Nile for agriculture, the Phoenicians developed their economies through their extensive trade networks in the Mediterranean Sea.
The Phoenicians were known for their seafaring skills and innovations, such as the invention of the multi-manned powered boat known as the bireme, which allowed them to easily navigate and trade throughout the Mediterranean.
