Why does the water on the waterfall in the mountain stream never run out? What is the science?

Because with the change of seasons, there will be ice and snow melting on the mountains every year to meet its needs, and their terrain difference is larger, and some rainy weather will also store water sources, with the reason for the change of seasons, the ice and snow of some mountains and rivers will melt, and then meet the needs of its water sources, and some of the sewage used in people's daily life will be circulated accordingly.

Most of the waterfalls in mountain streams are formed by the gushing of groundwater or the melting of glaciers at the top of the mountain, so the amount of water is not large, so it can flow forever.

There is no scientific principle, but there is a relatively sufficient source, so the flow is inexhaustible.

Because the source of the waterfall often has a stream or a small river, they can provide a continuous flow of water to the waterfall, so that the waterfall will form a situation that flows down without water shortage, and after the waterfall flows down, it will flow into the river and stream, so it is a cyclical phenomenon.

The water formed by the snow on the high mountains, as well as the rain and the river water, are the water sources of the waterfall, and the waterfall is a phenomenon similar to "dumping" formed by the difference in the height of the terrain through which the river flows.

This is because there is a river, and as long as the river is not diverted, it will flow forever under normal circumstances, and it is caused by low water.

First, the reason why the water of the waterfall does not flow endlessly.

The reason why the water of the waterfall does not flow is that in fact, in the actual situation, the water of the waterfall can be exhausted, such as the water that cannot be paved with oil, because of man-made reasons, or natural reasons are exhausted. In this case, the water of the waterfall will still run out on a certain day. The waterfalls we usually see give us the feeling that the water of the waterfall is not endless, because there is always a water source on it, but if the time is long enough, once the geographical situation of the upstream has changed, it is because people use a lot of water resources, and after reaching a certain limit, it is very likely to be cut off, and the water of the waterfall can be exhausted.

Second, the method of judging whether the scenic waterfall is real or false.

There are many scenic spots due to the lack of highlights, so there may be some artificial waterfalls, that is, the so-called fake waterfalls, directly according to the following methods to judge the truth of things, in the hot summer, the water of the waterfall is cold, if it is a fake waterfall, will it be cold and a little warm. If it is in the cold winter, then the water of the waterfall is warm, but the fake waterfall water is cold. <>

In fact, whether it is people or many things, it will be like a waterfall, with the passage of time, quietly some changes, for those real and still existing scenery, we should feel lucky for this, and then appreciate carefully.

There are many kinds of water sources of waterfalls, among which the more common ones are streams and springs, in addition, the water formed by snow on the high mountains, rainwater, and river water are all the water sources of waterfalls, and the waterfalls are similar to the phenomenon of "dumping" formed by the difference between the height of the terrain through which the river flows, the river continues to water, and the waterfall will not flow out, but with the difference between the river and the dry season, the water volume of the waterfall is also different.

A waterfall is a sudden vertical drop of flowing river water and is the main block in the flow of the river. In most cases, rivers use erosion and siltation processes to smooth out irregularities in their path. After a period of time, the longitudinal section of the river will form a smooth arc, with the steepest at the source and the gentlest at the estuary.

The waterfall interrupts the arc and shows the progress of the erosion process.

Waterfalls are also known as river falls and sometimes large waterfalls, the latter being especially used when talking about large volumes of water. Lower, less steep waterfalls are called cascades, a name commonly used to refer to a series of small falls along the river. Some sections of the river have a more gentle slope, but turbulence and white water occur correspondingly at the local increase in the slope of the river, and these sections of the river are called rapids.

According to scientists, there are many reasons for the formation of waterfalls, the main ones are: the rocks that make up the bottom of the riverbed are soft and hard.

The degree is inconsistent, and it is violently eroded by the impact of the river, forming a steep ridge, and the hard rock is relatively overhanging, and the river flows here, and then rushes down to form a waterfall. It can also be said that the river flows in the river and meets.

When the riverbed is steep, it falls down and forms a waterfall. In addition, there are also landslides, faults, and lava blockages.

Plugs, glaciers, etc., form waterfalls.

Waterfall [Cause].

In geology, it is called water falling, that is, the river water falls vertically when it flows through faults, depressions and other areas. The waterfall is a temporary feature during the time of the river, and it will eventually disappear. The rate of erosion depends on the height of a particular waterfall, the flow rate, the type and structure of the rock in question, and a number of other factors.

In some cases, the location of the waterfall recedes upstream as a cliff or ridge is washed away by currents; In other cases, the erosion tends to cut deep downwards and obliquely through the entire section of the river containing the waterfall. Over time, any one or both of these factors are at work, and the inevitable tendency of the river is to wipe out any waterfalls that may form.

The energy of the river will eventually create a relatively smooth, concave upward longitudinal profile. Even when gravel, which is a tool for river erosion, is not present, the energy available for erosion at the base of a waterfall is significant. One of the characteristic features associated with waterfalls of any size, as well as with flow and height, is the presence of dip pools, which are basins carved out of the river channel below the fall.

In some cases, the depth of the dip pool may approximate the height of the cliff that caused the waterfall. The dip pool eventually caused the collapse of the cliff slope and the retreat of the waterfall.

The cliff that caused the water to fall will continue to collapse under the strong impact of the current, causing the waterfall to retreat upstream and reduce its height, eventually causing the waterfall to disappear.

The flying stream went straight down to 3,000 feet, and it was suspected that the Milky Way had fallen for nine days.

That's all the ancients said.
