Which two rivers are significant to Kentucky's geography?

The significance of the Ohio and Mississippi rivers to Kentucky's geography lies in their impact on transportation, trade, and the state’s natural resources. The Ohio River forms the northern border of Kentucky, serving as a critical waterway for commerce and travel. It connects to the Mississippi River, one of the longest rivers in the United States, which plays a vital role in the economy by facilitating shipping and transportation of goods. Additionally, both rivers contribute to the ecological diversity of the region and provide recreational opportunities for residents and visitors alike.

In contrast, the other options include rivers that either do not flow through or connect to Kentucky in a significant way or are not related to its geography. For example, Kentucky and Tennessee are states, not rivers, while Potomac and Arkansas rivers are geographically relevant to other states but not to Kentucky's core geographical features. The Nile and Amazon rivers are located in different parts of the world altogether and do not have any direct bearing on Kentucky's geography.
