The longest river in the world is the Nile, located in Africa. It stretches approximately 4,135 miles (6,650 kilometers) from its source in Burundi to its mouth in Egypt, where it empties into the Mediterranean Sea. The Nile is historically significant and has played a crucial role in the development of ancient civilizations, particularly Egypt. It provides water for agriculture, transportation, and supports diverse ecosystems along its course. The river is also home to various species of plants and animals, making it an important ecological hotspot. Overall, the Nile stands as the longest and most iconic river globally.
Can you imagine what it would have been like to grow up during the time when Abraham Lincoln was a young boy? The hills of Southern Indiana, where he lived, were still wild and considered the frontier to the families who settled there.
When he was young, Lincoln worked as a ferryman on the Ohio River for a short period of time. He also embarked on a long journey down the Ohio River and then all the way down the Mississippi River to New Orleans on a flatboat. These river adventures played a significant role in shaping him into the leader he would later become.
Rivers offer numerous opportunities for adventure. While many people nowadays choose to use cars and airplanes to reach their destinations, it is still possible to navigate down rivers by boat.
If you take a look at a map, you will notice that there are thousands of rivers that wind their way across the world. These rivers not only offer tens or hundreds of miles of fun, but thousands of miles of natural excitement. If you are up for a challenge, try sailing on the longest river in the world.
However, which river holds this title? Although it may seem like a simple question, the answer is not so straightforward. Determining how to measure rivers and deciding where exactly a particular river begins and ends are tasks that scientists find difficult to agree upon.
For instance, most of the major rivers in the world are actually part of larger river systems, so it can sometimes be challenging to determine the starting point of a specific river. Most scientists nowadays choose to measure the length of the longest continuous river channel within a particular system.
A river’s size can also be measured in terms of its magnitude and volume, rather than just its length. Thus, crowning the “largest” river may not be the same as identifying the “longest” river.
Despite these challenges, most scientists concur that the Nile River is the longest river in the world. Flowing north through eastern Africa and emptying into the Mediterranean Sea in Egypt, the Nile River stretches an astounding 4,258 miles. However, due to the difficulties in measuring rivers, some estimates place the Nile’s length at about 4,135 miles.
Regardless of the measurement used, the Nile River is still longer than its closest competitor, the Amazon River, which passes through the South American countries of Peru, Ecuador, Colombia, and Brazil. According to the United States National Park Service, the Amazon is approximately 3,980 miles long.
Brazilian scientists who have recently taken new measurements of the Amazon argue that it should be considered the world’s longest river, with a length of 4,345 miles. However, their findings have not yet been validated by the rest of the scientific community.
Even if it is not the longest river in the world, the Amazon still has its own merits. Not only is it the widest river in the world (some parts of the Amazon reach a width of 120 miles during the rainy season), but it is also the river with the largest volume of water. In fact, the Amazon contains approximately 20% of the world’s fresh water supply!
Give It a Try
Are you ready to experience the river? Make sure to explore the following activities with the assistance of a friend or family member:
Within a 100-mile radius of your location, use an atlas or an online map website to discover the rivers in the area. Determine the number of different rivers and identify the largest one. Compare the size of the largest river in your area to the Nile and the Amazon.
To accurately measure a river, it is crucial to know its starting point. However, determining where a tributary ends and a river begins can be challenging. Read the article “Where is the Amazon River & Where Does It Start and End?” to understand the difficulties involved in this process.
Take on the challenge of measuring the Nile and the Amazon rivers. Consider the methods and modern technology you would use for such a monumental task. Decide whether using a boat or relying on modern maps and satellite images would be more effective. Create a plan for measuring these mighty rivers and share it with a friend or family member. Get their opinion on the best approach.
