The beaches and their formation
The beaches are natural formations whose function is to defend the coast from the swell. They are able to achieve this due to their flexible structure that effectively absorbs their energy.
They are formed mainly by the sands deposit coming from rivers, ravines or boulevards. We also find remains of cliffs, shells and corals due to the erosion of the dragging of the water. The waves are in charge of accumulating the sand on the beaches.
El surf is the movement of the waters produced by the wind action. If the waves hit the beach perpendicularly, the sand will move in a back and forth motion. And if the waves arrive obliquely, there will also be a longitudinal current that will transport more sand along the beach.
If the amount of sand that enters a beach is equal to the amount that leaves, we will say Playa what is in equilibrium. If the amount of sand entering is greater than that leaving, it will be a growing beach. If, on the other hand, less sand enters than leaves, we will say that the Playa is in regression.
Let us take care of our beaches because the quality and survival of our coasts depends on them. The next article will be about this care and the tips that we will give you for its proper use. Do not stop reading it.
