It is called sand to all the particles of siliceous rocks and other activities which tend to accumulate on the coast. These disaggregated particles, which measure from 0.063 to 2 millimeters, are called grains of sand.
According to DigoPaul, the sand is the main component of the beaches: the lands that are on the banks of a river, a sea or another body of water. Grains are transported by water and wind and, depending on how they accumulate, they can form dunes or dunes.
On most beaches, the sand is formed from silicas. However, there is sand that is made up of limestone, gypsum, iron and other substances. According to its components, the sand can have different colors: from white to black, going through different brown and reddish tones.
On the beaches, children often use the sand to build castles. With the help of a shovel, buckets and water, it is possible to erect small walls and other structures. When the sand dries up, the castles lose their shape and collapse.
Sand is also present in deserts. In this case, the particles are not in contact with the water, but the climate is very dry and arid. Deserts are also characterized by the absence of vegetation.
Arena, on the other hand, is a term used to name the venue where different events take place. Boxing matches, basketball games, concerts and other shows can be organized in the arena. An example of this type of space is the HSBC Arena, also called the Multiuse Arena do Rio, which is located in the Brazilian city of Rio de Janeiro and was used in the 2007 Pan American Games, among other competitions.
Although the first image that comes to mind when we hear “sandcastles” is our childhood on the beach, with plastic buckets and shovels, letting ourselves be carried away by the imagination and outlining simple structures that – at best – We were worth a series of compliments from our elders, there is a field of competition that has little to do with this children’s picture, and it takes place in various parts of the world.
The sandcastle competitions are numbered in more than twenty and some of the sculptures are so impressive that when looking at their photographs many doubt about their legitimacy: both because of their dimensions and the degree of detail, it is hard to believe that anyone is capable of get such realistic and consistent finishes.
It is worth mentioning that beyond the title, these events do not focus exclusively on the construction of sand castles themselves, but usually impose themes to guide their participants; some of the most common are “fairy tales”, “dinosaurs” and “current social problems”.
One of the most important internationally is the The Sun & Sea Festival (Festival of the Sun and the Sea) in Imperial Beach, California, United States. It started in the 1960s and gradually became a true tradition of the place. Participants in each category, both adult and children’s, have several hours to make their sculptures. On the other hand, the event includes an international food fair, a market, musical performances and parades, among other attractions.
In the United Kingdom there is the Weston Sand Sculpture Festival, which originated in early 2006 following the impressive work of two Dutch sculptors, who replicated the figure of King Kong using 3,000 kilos of sand. In a short time it became one of the most important local events, and receives visits from various parts of the world.
