What do you call a river that flows into a body of water (lake, Ocean) which is shallower than the river?

Most freshwater lakes have zones of temperature according to depth, known as stratification. Have you ever noticed how when you wade into a lake or dive down you encounter a layer of water that is much colder? This is stratification. Fresh water is densest, or heaviest, when it is 39 degrees Fahrenheit.  \n\nDuring late summer the air cools the surface water till it begins to sink, forcing lighter less dense and warmer water to the surface. If at some point all the water in the lake gets to 39 degrees, this temperature-induced mixing will stop, but wind can still force the water to mix. \n\nThis mixing action by wind and cooling is called turnover. \n\nDuring spring, the process reverses itself. Ice melts at the surface. When ice is on the surface of a lake the coldest water is often just under the ice. As this water warms up and becomes the same density and temperature as the deeper water it takes very little wind energy to cause the water to mix, or turnover. As the surface water warms even more, it becomes less dense than the deeper water and forms a stratified layer. After this stratification forms it will remain stratified.

River morphology (shape) is controlled by a number of characteristics. River channels can be broken into three types, straight rivers, single channel meandering rivers, and braided rivers (multi-channel). The amount and size of the sediment the river carries, the slope of the river channel, and the amount of water in the river determine the shape of the river channel. \n\nStraight rivers tend to have the lowest sediment load and the lowest slope. Meandering rivers have slightly more slope, and much more sediment load, and braided rivers have both the highest slopes and greatest sediment loads. \n\nRiver channels in cross section often have a cup-like  shape with the deepest portion, known as the thalweg, found on one side or the other. This thalweg has the highest flow velocity and because it flows faster it can cut into the bank it is closest to, while the shallow part of the river slows down and drops sediment. This action causes both meandering rivers and braided rivers to move their channels from side to side in a valley over time. Straight channel rivers also have thalwegs that move but the effect is much less. \n\nAs rivers go from mountainous terrain to nearly flat valleys they change from braided streams and rivers to meandering rivers. As they approach sea level they form deltas where the flow often separates into separate branching channels. A great deal of the sediment load of the river is deposited on the delta, and as the river flows into the ocean it builds the delta outward. Rivers like the Mississippi have built deltas far out into the ocean with sediment piles that are several miles deep.

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.

fresh water --- the source is the snow melt from the Rocky Mountains.  The Hoover Dam impounds the Colorado River forming Lake Mead.  The "Lake" in Lake Mead is a misnomer --- it is technically a reservoir since it is formed by the impounding the Colorado River.  A true "lake" has no dam -- like Lake Tahoe or Crater Lake.

the wider the stream, the slower it flows.

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!

They are the opposite ends of the river--the mouth is where the river empties into another body of water; the source is the headwaters, or the little streams that feed into the river. The outlet is the same as the mouth.

An ocean is a global interconnected body of salt water.\n\nA sea is a large expanse of saline water connected to an ocean.\n\nA lake is a body of water surrounded by land that is either freshwater or salt water.  The majority of lakes are freshwater.

A pond is usually smaller than a lake. A pond usually has mostly still water, while a lake may have currents. Ponds are overall much more shallow than lakes, which can be very deep. Typically, a pond has no surface outflow draining off water and ponds are often spring-fed. A lake is usually fed by several streams. The water temperature of a pond is usually the same throughout, while a lake may have layers of different temperatures in its depths. Lastly, ponds have more plant life than lakes. Plants may completely cover a pond, but lakes only have plants on the edges.

The waves taht you see created on a larger body of water such as a lake or an ocean are largely created as a result of wind acting upon the surface of the water.   There are three components that determine how big the waves become, they are fetch, intensity and duration.\n  Fetch is the available surface area presented to the wind.  A larger body of water will have a larger fetch area, allowing for the wind to develop its effects on the surface.  Thus a larger body of water will typically have larger waves.\n  Intensity is how hard the wind is blowing.  Stronger winds make bigger waves.\n  Duration is how long the wind has been acting on the water's surface.  A quick breeze may cause the surface to ripple, but it takes time and a more prolonged wind to start developing the larger waves that most people are accustomed to seeing on the ocean.\n\nSo, with a river, there are indeed waves, but just not as large as a big lake or the ocean because there just isn't enough fetch to build big waves.  One some large rivers (such as the Mississippi) there are wider areas, sometimes more than a mile wide.  In these sections of a river, it is not uncommon to get waves up to several feet in height on a windy day.

As water flows down rivers into the ocean, minerals dissolve in it. When the water gets to the ocean, solar radiation vaporizes the water and leaves the dissolved minerals behind. Over time, millions and millions of years, the concentration of these minerals increases.  The Salton Sea in California is an example of a speeded up version of the process. About the year 1909, the Colorado River was diverted from its course and flowed into the Salton Sea, which was a dry low area. It took some time to block the diversion. By the time it was complete there was a new fresh water lake there.  During the last 90+ years, that fresh water lake has turned into a sea more saline than the ocean.

Unless the land it totally flat, rivers of water run downhill. The vast percentage of rivers on the planet flow in a southerly direction because the source (usually in the mountains) is to the north of the mouth. \nIf the source of a river is at a higher elevation than the mouth, that river will run from the source to the mouth. However, if that (higher) source is to the south of the mouth, that river will then flow to the north (downhill).

Oh! Deltas! Estauries are sunken river mouths. Good examples: China's Pearl River Delta, Argentina's La Plata, Maryland's Chesapeake Bay.\n\nBird's foot or digitate, that's where the river branches out at the mouth. Nile River Delta, the classic. Niger River Delta, and Mississippi Delta. \n\nArcuate. Hmmmm...I'm guessing it's roundish, but...I'm going to have to look it up! Yes, it's arc shaped, and the Ganges Delta is an example. Darn it! The Nile is, too! Oooh! Nice photo illustrating the Nile Delta article! Oh the Niger delta is, too! Guess that leaves the Mississippi Delta as a bird's foot!
