Which river connects Lake Ontario to the Atlantic Ocean?

• A. The Mississippi River
• B. The Saint Lawrence River
• C. The Ohio River
• D. The Ottawa River

Answer: (B)

The Saint Lawrence River is the primary waterway that connects Lake Ontario to the Atlantic Ocean. After water flows out of Lake Ontario, it enters the Saint Lawrence River, which serves as a crucial part of the Great Lakes-St. Lawrence Seaway system. This river not only facilitates navigation for ships traveling to and from the ocean but also plays a vital role in the ecology and economy of the region. It is important to note that other rivers mentioned in the choices serve different geographical areas and do not connect Lake Ontario to the Atlantic Ocean. The Mississippi River, for example, flows through the central United States and empties into the Gulf of Mexico, while the Ohio River is a tributary of the Mississippi and is located further south. The Ottawa River, located in Canada, flows into the Saint Lawrence River but does not connect directly from Lake Ontario to the ocean. Thus, the Saint Lawrence River is the only correct choice in establishing the connection between Lake Ontario and the Atlantic Ocean.
