What is the name of the longest river in the world? There are the highest mountains, the most populous countries and the longest rivers in the world. There are many rivers in the world, which I believe everyone has learned at school. So, what's the name of the longest river in the world?
What is the name of the longest river in the world? The longest river in the world is called the Nile.
The Nile runs through the northeast of the African continent, flows through Burundi, Rwanda, Tanzania, Uganda, Ethiopia, Sudan and Egypt, crosses the largest Sahara desert in the world, and finally empties into the Mediterranean Sea. The basin covers an area of about 3.35 million square kilometers, accounting for one ninth of the African continent, with a total length of 6,650 kilometers and an average annual flow of 3 100 cubic meters per second, making it the longest river in the world. The Nile Valley is divided into seven regions, namely, the lake plateau in East Africa, the mountainous river region, the white Nile region, the blue Nile region, the atbara river region, the Nile region north of Khartoum and the Nile Delta.
The Nile runs through Egypt, with a total length of 65,438+0,350 kilometers, and irrigates 2.4 million hectares of land. In Egypt, where the desert occupies 96% of the land area, the Nile means life. In the Nile Valley and Delta, which only occupy 3% of the land area, 96% of the Egyptians are gathered! On both sides of the Nile, there are green wheat fields and cotton fields, orange forests and banana forests, sugar cane fields and corn fields like green cotton curtains ... Egypt's long-staple cotton is white and bright, known as "platinum", accounting for about 1/3 of the world's total output.
The Nile is characterized by frequent flooding. At the beginning of July every year, the Blue Nile flows into the mainstream with the mud washed down from the mountains like a tsunami, and the water volume of the Nile increases greatly. The Egyptians looked up and prayed to the horizon while anxiously watching the changes of the river. The Nile is by no means a tame river, and its flow will fluctuate greatly. More than 80% of the Nile's water is provided by the Ethiopian plateau, and the rest comes from the lakes in the East African plateau. When the flood comes, it will overflow the river bed, wash away the salt in the soil, deposit a lot of minerals and organic matter brought from the upstream in the fields on both sides of the river, and widely apply a layer of natural fine fertilizer to the cultivated land in Egypt.
The longest controversy
The longest river: Nile, Amazon is controversial. The Nile is recognized as the longest river in the world, with a total length of 6695 kilometers. After a long journey, the expedition team composed of Brazil and Peru discovered the new source of the Amazon River, making it the longest river with a length of 6,800 kilometers, but it caused controversy among experts. The US Geological Survey satellite confirmed that the longest river in the world is the Amazon River.
So far, different geographers have measured the length of the Amazon River between 6259 and 6800 kilometers (3889 to 4225 miles). Generally speaking, the Amazon River is "at least" 6,400 kilometers (4,000 miles) long. The reported length of the Nile is between 5,499 and 6,690 kilometers (34 17 to 4 157 miles). Overall, it is about 6650 kilometers (4 130 miles) long.
In 2007, a field trip by Brazilian scientists concluded that the Amazon River is actually 65 kilometers longer than the Nile. In 2008, the Brazilian National Institute of Geography and Statistics (IBGE) recalculated the length of the Amazon River through satellite images. They used the source calibrated by Brazilian scientists in 2007 to calculate the length of the Amazon River, and the calculated length was 6,992 kilometers (4,345 miles). Using the same technology, the length of the Nile is 6853 kilometers (4258 miles), which is longer than the previous estimate, but still shorter than the Amazon River.
However, there are many factors that will affect the measurement results, such as the determination of the starting and ending points of rivers.
