What body of water do the Mississippi River and the Rio Grande flow into?

a. Pacific Ocean

b. Atlantic Ocean

c. Gulf of Mexico

d. Lake Superior

Mississippi River flows into the Gulf of Mexico - so that's how I know that the correct answer is c!

There is also a Rio Grande that flows into the same Gulf, but there are actually many rivers of this name, as it just means "Big River" in Spanish.

The answer is C - Gulf of Mexico
