The mouth.\nLakes,streams from mountains.The ice from mountains melt,causing tiny streams of water running down the mountain.As it goes along,more water is collected(rain etc.),and it becomes a small river.There are three stages of a river.First,the valley is narrow,second,it gets wider,and third, it is almost flat and very wide.it ends at the sea. \nHope this helps :)

Yangtze-runs through China.\n\nThe Yangtze River or Chang Jiang is the longest river in Asia and the third longest in the world after the Nile in Africa and the Amazon in South America. \nThe river originates in a glacier in the Dangla mountains on the eastern part of Tibetan plateau. It then runs through the eastern part of Qinghai, turning southward down a deep valley at the border of Sichuan and Tibet to reach Yunnan. In the course of this valley, the river's elevation drops from above 5000 m to less than 1000 m. It enters the basin of Sichuan at Yibin. While in the Sichuan basin it receives several mighty tributaries, increasing its water volume significantly. The river then cuts through Mount Wushan bordering Chongqing and Hubei to create the famous Three Gorges. Eastward of the Three Gorges, Yichang is the first city on the Yangtze Plain. After entering Hubei, the Yangtze receives more water from thousands of lakes. The largest of the lakes is Dongting Lake, which is located on the border of Hunan and Hubei provinces, and is the outlet for most of the rivers in Hunan. At Wuhan it receives its biggest tributary, the Han River, bringing water from its northern basin as far as Shanxi. At the northern tip of Jiangxi, another lake, Lake Boyang merges into the river. The river then runs through Anhui and Jiangsu provinces, receiving more water from innumerable smaller lakes and rivers, and finally reaches the East China Sea at Shanghai. Actually, four of China's five main freshwater lakes contribute their waters to the Yangtze River. Traditionally, the upstream part of the Yangtze River refers to the section from Yibin to Yichang; the middle part refers to the section from Yichang to Hukou, where Boyang Lake meets the river; the downstream part is from Hukou to Shanghai.

RIVERS THAT FLOW NORTH \n"To many Americans . . . , north is the wrong way for a river to flow,  which leads to geographic confusion." \n-- Angus Phillips, "Simple Gifts of the Shenandoah", National Geographic, December 1996\n\n"The important thing to remember is that to a river, or more precisely to the drops of water that make up the river, "down" has nothing to do with compass points -- with latitude or longitude -- only with altitude."\n\n2Surprisingly, four of the world's ten longest rivers flow generally in a northern direction. The Nile in Africa, the Ob-Irtysh and the Lena in Eurasia and the Mackenzie-Peace in North America."\n\nLots more information at the site below

there are many rivers in the world which passes through young folded mountain systems . , at the sea level froming gorges . They are believed to be antedecent rivers, which originated before the mountain systems (.When the mountains started rising the rivers cut their courses at the same rate as that of mountain rise.) EX.   Himalays- INDUS, satluj,alaknanda,KOSI,ARUN,TSANGPO/ BRAHMA PUTRA,KALI...\n outside this- woonski (vermont ,USA ), amargosa river in eastern california..

I belive you are tallking about a source for water.  It could be several thing, a glacier melting,  snow pack from the winter or natural springs.  Where the water in a mountain finds a hard rock and then will find the path of least resistance,  sometimes out the side of the mountain which would be a mountain spring.  But the mountain source is just the fact that the river is starting in mountain,  from a spring, winter melt off or glacier.  hope that helps.

Deltas and Estuaries are created at the mouths of rivers.\nAnother landform that is created close to the mouth of a river is an ox bow lake.

World's Shortest River\n\nThe Roe River is recognized by the Guinness Book of World Records as the world's shortest river. The Roe flows 200 feet between Giant Springs and the Missouri River near Great Falls. The Roe River competes with the D River in Lincoln City, Oregon for the title of the shortest river. Both rivers have been measured on different occasions, with lengths varying from 58 feet to 200 feet. Schoolchildren in Great Falls campaigned successfully to have the Roe River placed in the Guinness Book of World Records. \n\nThe source of the Roe River, Giant Springs, is the largest freshwater spring in the United States. The longest river in the state is the Missouri River. The Missouri flows 1,029 miles, from Three Forks to the North Dakota border.

The source of the Amazon River is not in Brazil - it is Peru. While the river has over 1,000 tributaries, the main source lies in the Andes in Peru, less than 100 miles from the Pacific Ocean even though it empties into the Atlantic Ocean. The Amazon is formed by the junction of two major headstreams, the Ucayali and the shorter Marañón. You can read about the recent discovery of the source in the first link.

The Niagara and Genesee Rivers in Upstate New York flow north. The Licking River in Kentucky flows north. There are probably many more.\n\nIn 1869, an earthquake hit Memphis, TN, causing the Mississippi to flow backwards (south to north) for 90 seconds!

wat r trivers? and u can learn about rivers in history. i have a REALLY good social studies teacher who told me that geo and history and very closely related. we learned bout the st lawerence river in history class!\n\nand bout the yangtze river...\nThe Yangtze River is the longest river in Asia and third longest in the world. The headwaters of the Yangtze are situated at an elevation of about 16,000 feet in the Kunlun Mountains in the southwestern section of Qinghai. It flows generally south through Sichuan into Yuanan then northeast and east across central China through Sichuan, Hubei, Auhui, and Juangsu provinces to its mouth, 3,720 miles, in the East China Sea north of Shanghai. The river has over 700 tributaries but the principal tributaries are the Hun, Yalong, Jialing, Min, Tuo Jiang, and Wu Jiang. The climate ranges from 96 degrees in the summer to cold, brisk temperatures in the winter. Precipitation is high due to the height of the mountains.  \nChina covers an area of almost 3.7 million square miles and is the most populous country on earth having more than one billion people. The bordering countries include Mongolia, Kazakhstan, India, Nepal, Burma, Vietnam and Korea. The People's Republic is led by Chinese Communist Party and governed by the State Council. The main language spoken is the Mandarin dialect of Chinese but there are more than 150 languages and dialects spoken throughout the country. Approximately 350 million people inhabit the region of the Yangtze. There is plenty of wildlife along the river as well which include the Tibetan antelopes, Mongolian gazelles, and snow leopards, just to name a few.  \n\nWaters of the Yangtze are often used for rice and wheat irrigation. It also has enormous and inexhaustible hydroelectric resources. In 1995 construction began on the Three Gorges Dam near Yichang and is scheduled for completion in 2009. The dam will measure about 600 feet and about 1.5 miles wide. The dam is expected to help control the flooding of the Yangtze River Valley. The Three Gorges (the Qutang Gorge, the Wuxia Gorge, and Xiling Gorge) will also be the largest electricity generating facility in the world. The hydroelectric generators will provide 1/9 of China's total power output. \n\nThere is a lot of controversy surrounding the construction of the dams. There are 140 villages, 1,600 factories and over 80,000 acres of growable land that will be destroyed. It may also cause animals to become extinct. The area is very prone to earthquakes because it lies directly on a fault line. Actually, the plateau and gorges were created by collision of the Indian-Australian plate, drifting northward, with the Eurasian plate that began over 40 million years ago and continues today. \n\n\n\n\n\n\n      Snaking its way 6,300 kilometres from western China’s Qinghai-Tibet Plateau to the East China Sea, the Yangtze River stretches nine provinces and serves as a drain for 695,000 square miles of land.  It is less in length only to the Amazon and Nile, and spans so many regions that it has acquired half a dozen names.  In the high Qinghai-Tibet Plateau, the Tibetans title it Dri Chu—Female Yak River.  The Chinese in the area know it as Tongtian He, Travelling-Through-the-Heavens River.  Where it borders Sichuan and runs through Yunnan, it is referred to as Jinsha Jiang, River of Golden Sand.  Often the word Wanli prefixes the common Chang Jiang (Long River), designating it Ten Thousand Li River. Only in the lower reaches does this great flood go by its name common to foreigners: Yangtze. \n\n        For over two centuries the Yangzte has served as a transportation highway and commercial thoroughfare.  Ocean-going vessels can navigate up the river for 1000 km and steamers can travel as far as Yichang, 1600 km from the sea.  A quarter of China’s ocean-going cargo enters the river between Shanghai and the sea.  Shanghai is known as the gateway to the Yangzte, spanning the Huangpu tributary just south of the

Southwest to Northeast. Head waters are the Great Lakes which start in Minnesota. The River starts out of Lake Ontario and heads up through Montreal, Quebec City, and finally hits the Atlantic Ocean in the Gulf of St. Lawrence near the Grand Banks.

Impossible to answer. No one has ever counted them all and how do you define a river? Here what we define as a river may de called a creek over there.\n\nGod is the only one I know who truely knows the answer to this question.\n\nThe answer would be in the 100,000's though.

Depends on the country you are talking about if its the US it would be the Mississippi or the Hudson, but if it England I would say it is the Thames, the Yangtze in China, in Africa the Nile, in Brazil the amazon, in Pennsylvania state the Ohio river is the most used. I hope this was helpful without more details i don't know

The Amazon river ends in northeastern Brazil, near the city of Belem, where it flows into the Atlantic Ocean.\n\nWhere a river begins is subject to intepretation.  Some consider it to be the farthest point up river, some the highest, and some as the path of greatest flow.  \n\nSo, there are a number of candidates in the Peruvian Andes that might be considered to be the beginning of the Amazon.

Did  you know that the longest river in the world is the Nile? Egypt's greatest river is 4,160 miles long! In fact, Africa has two of the ten longest rivers. The Congo, which flows through central Africa, is Number 8 at 2,718 miles long.\n\nWhat's the second longest river? Why, the Amazon, of course! It is about 4,000 miles from start to finish, winding its way through most of South America.\n\nChina lays claim to Numbers 3 and 4: The Yangtze River is 3,964 miles long, and the Huang He is 3,395

Traditionally river systems have been classified according to their stage of development as young, mature, or old. The young river is marked by a steepsided valley, steep gradients, and irregularities in the bed; the mature river by a valley with a wide floor and flaring sides, by advanced headward erosion by tributaries, and by a more smoothly graded bed; and the old river by a course graded to base level and running through a peneplain, or broad flat area. The age classification of rivers is diminishing in popularity now that quantitative studies of river behavior are more common.
