What are the four largest river systems of the US?

Answer 1

The longest river is the Nile in Africa at 6695 km/4160 mi long The Amazon in South America is 6400 km/4000 mi long The Yangtze in Asia is 6300 km/3900 mi long The Yellow in Asia is the fourth longest river at 5464 km/3395 mi, but the Mississippi in North America is 5970 km/3710 mi long if measured from the headwaters of the Missouri River to the Gulf of Mexico. The Mississippi River, from Lake Itasca in Minnesota to the Gulf of Mexico, is 3,770 km (2,340 mi) long.

Answer 2

For river systems or watersheds, the most stable feature is the drainage basin area. Comparing the size of this feature, The four largest US rivers systems are:

The Mississippi River basin Area is 4,760,000km2, over reaching, slightly, our northern border with Canada in the plains area, but otherwise completely within US. Borders (This basin accounts for about 40% of the total land mass of the contiguous (lower 48) USA, roughly the area between the Rockie and Appalachian mountains.

The St. Lawrence River Basin Area is 1,344,200 km2 including the Great Lakes. 62% of the basin is in Canada.

The Rio Grande Basin Area is 870,000 km2 with about 35-40% in Mexico. This area includes endorheic (closed) watersheds within the greater system, not currently contributing flow to the river, The current active river basin area is approximately half this size.

The Yukon River Basin Area is 832,700 km2, with about 61% in Central Alaska, and about 39% in Canada's Yukon Territory and British Columbia.

Answer 3

The four largest river systems in the US are the Mississippi River system, the Missouri River system, the Yukon River system, and the Rio Grande River system. These rivers play crucial roles in the country's ecology and economy, supporting diverse wildlife and providing water resources for agriculture, industry, and communities.
