blend together

My home country of Brazil is very rich in natural resources. One of them is the famous Amazon River, one of the largest and longest rivers in the world. It is formed by two separate rivers, the Solimoes and Negro. Interestingly, they flow together for a number of miles before the waters blend, due to the rivers having very different origins, speeds, temperatures, and chemical compositions. After several miles, the waters finally blend together, becoming a river different than its individual parts. Only after these parts merge, the Amazon River becomes so powerful that when it reaches the Atlantic Ocean, it pushes back the seawater so that fresh water can still be found for many miles out into the ocean.
