Rivers and Streams

When Rivers Run Into the Ocean
Where rivers meet the ocean is called the mouth of the river. Soil and dirt carried by these rivers is deposited at the mouth, and new land is formed. The new, soil-rich land is known as a delta. 
Aerial View of the Amazon River DeltaThe Amazon River is the second longest river in the world. Like all large rivers, the Amazon deposits a lot of soil and sediment, forming a delta, as it enters the ocean. Its delta is located in Brazil. 

As rivers prepare to enter the ocean, they tend to get off course and branch into many directions, creating many small islands in the delta region. This is particularly true with the Amazon River, as you can see. 

Aerial View of the Mississippi River DeltaScattered across the delta at the end of the Mississippi River is the city of New Orleans. By the time the mighty Mississippi winds its way south through America's center it becomes a force well over a mile wide. It's a very dramatic sight to watch as this mammouth river spills into the ocean.

Because the Mississippi watershed drains much agricultural land, it has high sediment content. The mud spilling from the river into the Gulf of Mexico is clearly visible in this picture. 

Aerial View of the Nile River DeltaThe Nile River is the longest and probably the most famous river in the world. As it flows toward the Mediterranean Sea from the mountains of central Africa, it grows in size. The Nile Delta is a very large and impressive sight. It is home to some of the most productive agricultural land in the Middle East.
