Why do rivers flow?

The river - like a perpetual motion, flows endlessly. But at the same time, perhaps, rarely anyone thinks about why it always flows in only one direction. The water is in endless motion. How can we explain such a life of rivers? Let's try to understand why rivers flow.

Why rivers flow

Everything is very simple! First, the solution lies in the properties of water. Namely, in its special property - very strong fluidity. Given the laws of physics and chemistry, we understand the reason for the constant movement of rivers. The primary role is played by the law of attraction of the Earth, which constantly affects the water of rivers.

An important role for choosing the direction of the riverplays the terrain on which it flows. As we know, all the rivers originate in the source, which can be all kinds: a lake, a swamp, an underground source or other water resource. The river ends its way to the mouth, which can also be absolutely any pond. And here, if we think about where the rivers flow from, we will understand - that from the highest point of our whole path.

After the information received, everything is finalfalls into place. It immediately becomes clear why the mountain rivers flow much faster than the rivers of the plains. Why no river ever stops its current. And why the rivers of Russia flow slowly. For Russia, this is due primarily to the relief of the entire terrain of our country, which has a huge length and, basically, a flat terrain. Rivers, at the same time, have a small force of water flow, because of what they can not build a new path, and they go around all obstacles. Change the direction of the river can only shift the earth's surface as a result of an earthquake that will change the level of the source and the mouth.
