What body of water borders Kentucky to the north?

The Ohio River borders Kentucky to the north, making it a significant geographical landmark for the state. This river serves as the boundary between Kentucky and several states to the north, including Ohio and West Virginia. It plays a crucial role in the region's ecology, economy, and transportation, historically serving as a crucial route for trade and movement. The Ohio River's importance goes beyond just being a border; it also influences the local climate and environment.

In contrast, the Mississippi River is much further to the west and serves as a border for other states, while the Cumberland and Tennessee Rivers are located within Kentucky but do not form its northern boundary. This distinction is vital for understanding Kentucky's geographical position and its relationship with surrounding states.
