Definition of Beach, Formation and How It Is Related to Waters

Perhaps one of the most used and enjoyed by the human being, the beach is considered a geographical accident that always takes place immediately after a mass of water, establishing itself as a limit to it. The beaches are unstable as they vary in size according to the constant movement of water, and this is especially clear in the beaches formed by the sea or the ocean that, unlike the waters of lakes or lagoons, are in permanent movement.

Formation of Beach

In general terms, it could be said that a beach is formed through the action of water. It moves and transports different types of sediments that are being placed in the place, thus forming areas of lower wateriness and greater land space. These sediments, however, are not permanent and that is why, depending on the tide, the size or extent of a beach can vary completely. In any case, the change is never total since the contribution of sediments is permanent and a stable surface is formed on which different activities can be carried out.

The beach is, without a doubt, a place of habitat for many aquatic species that can live in both aquatic and terrestrial spaces. At the same time, in many cases the beaches have an important vegetation all around, which always has to do with the weather and the type of temperature that occurs in each specific region. Obviously, this is so when we do not talk about the intervention of the human being.

As for recreational place, the beach is currently one of the most popular tourism options allowing us to come into contact with the sea or the appropriate course of water activities to relax and rest and be exposed to air free. A large number of beaches around the world are some of the most important and visited tourist destinations, growing more and more and offering the public an incredible variety of options to enjoy the experience . In many cases, some specialists of the tourist activity have taken advantage of the commercial benefits that a beach grants and as a result of this situation it has been created artificial beaches that have little and nothing to do with nature but are definitely a tourist attraction more.

The presence of the human being undoubtedly makes the natural space of the beach change profoundly. This not only has to do with pollution , but also with the erosion and alteration that can be generated by having large numbers of people moving. As a result, many beach areas have completely changed their natural structure and have become unfit for human presence.

What is the difference between Beach and Sea?

The beaches are one of the most popular areas of the oceans. In fact, a beach is the part of the sea where it meets the mainland and where the accumulation of sediments allows its gradual arrival. Because of this reason it is not often that there is confusion between what the sea is and what a beach is. However, it would be useful to know the definition of each one to avoid any possible misuse of both terms.


Sea is the mass of salt water that is found along most of the earth’s surface. The seas are part of the oceans. Some brackish (salty) lakes are considered seas.

As for the beaches, these are deposits of sediments such as sand, gravel and others. The beaches are the banks of the sea. This means that they are the point at which the sea meets a high portion of land that it does not cover.

Other data

There are some types of seas. For example, the coastal seas (shallower than the ocean and are coastal), the continental seas (found within the continents) and the closed seas (the lagoons).

Beaches are commonly associated with tourism

Since the sea gradually reaches land on many beaches, these are the ideal place for bathers. The beaches offer shallow areas where you can enjoy the sea in a relatively safe way.


Among the most popular seas are the Caribbean Sea, the Baltic, the Mediterranean, the Dead Sea, the Black Sea and the Red Sea. However, there are other seas equally relevant tourist, commercial or ecologically.
As for the beaches, there are many beaches famous for their beauty. For example, Bondi Beach in Australia, the beaches of Rio de Janeiro in Brazil, those of the Caribbean, etc.

Other beaches appreciated at the tourist level are the Mexican ones, such as Cancun, Puerto Vallarta, Los Cabos, etc.

The beaches of the Mediterranean like those of Greece and Italy and those of Southeast Asia like those of Indonesia and Thailand are considered among the most beautiful in the world.

Some figures

  • There are about 61 seas in the world.
  • Europe is the continent with more seas, followed by Asia and then America.
  • Other planets have seas, they are not exclusive to Earth.
  • Sun and beach tourism or coastal tourism is the most popular worldwide. In fact, it is estimated that this type of tourism represents 80% of tourism revenues worldwide.
