Why do seas and oceans have waves, but rivers and lakes do not?


The movement of waves is familiar to every person who has lived or at least visited the coast of the sea. At the same time, in different reservoirs, the strength of the waves is different, and in some of them they are not at all. How are they formed? How giant killer waves appear

Water has great mobility and is easy to

For example, the wind transfers part of its energy to the sea surface due to frictional force, creating capillary (small) waves. When the gust increases, the water in this place resembles a seething cauldron: small waves merge with each other, forming large ones, everything will move at different speeds and collide.

Their energy is transmitted for thousands of kilometers around, setting in motion more and more water molecules. Approaching the coast, this mass will be ordered, taking the form of swells — even ridges, divided into groups from 3 to 9 with small intervals of calm between them.

As a rule, the wider and deeper the body of water, the faster and longer the waves will be.

In small lakes and rivers that do not have a deep bottom and large areas, there will never be waves — there will be small ripples. In this case, passing ships can create vibrations that reach the coast in the form of small waves.

And although most rivers and lakes are calm, there are examples of lush bodies of water in the world. For example, on Baikal and Ladoga

The ebb and flow of the Amazon River is the largest river in the world. Wave height

Alone in the world of waves are wandering waves — lonely, giant crests reaching

Such giants are born in different parts of the planet. It is impossible to predict them, and while they remain formidable, we remind man that not everything on the planet is subject to man.
