Which two rivers are significant in the geography of Oklahoma?

The Red River and the Arkansas River are significant in the geography of Oklahoma for several reasons. The Red River forms the southern boundary of the state, serving as a natural border between Oklahoma and Texas. This river plays a crucial role in the region's ecosystem and agriculture. It is also associated with important historical events, including the migration and movement of various Native American tribes.

The Arkansas River is the longest river in the state, flowing through Oklahoma and providing vital water resources. It contributes to the state's economy through activities such as agriculture, recreation, and transportation. The river's watershed is significant for draining a vast area, impacting both the ecology and economy of Oklahoma.

The combination of these two rivers greatly influences the state's landscape, agriculture, and development, making them essential features of Oklahoma’s geography.
