Final answer:
The Bosphorus Strait separates Europe and Asia, connecting the Black Sea with the Sea of Marmara, which leads to the Aegean Sea and the Mediterranean Sea.
Step-by-step explanation:
The body of water that separates Europe and Asia is known as the Bosphorus Strait. This strait connects the Black Sea to the north with the Sea of Marmara to the south, which in turn is connected to the Aegean Sea and ultimately the Mediterranean Sea through the Dardanelles Strait.
These connections form a vital maritime route between the inland areas of Eastern Europe and the Mediterranean, allowing for significant trade and cultural exchanges throughout history.
