Sand is the main component of deserts and beaches.
Sand is a set of siliceous and other rock particles that usually accumulate on the coast. These disintegrated particles, which measure 0.063 to 2 millimeters , are called grains of sand .
This is the main component of beaches : the land that is located on the banks of a river, sea or other body of water. The grains are transported by water and wind and, depending on how they accumulate, they can form sandhills or dunes .
Sand on beaches and deserts
On most beaches, sand is formed from silica. However, there is sand that is made up of limestone, gypsum, iron and other substances. Depending on its components, sand can have different colors : from white to black, through different brown and reddish tones.
On beaches, children often use sand to build castles . With the help of a shovel, buckets and water , it is possible to build small walls and other structures. When the sand dries, the castles lose their shape and collapse.
Sand is also present in deserts . In this case, the particles are not in contact with water, but the climate is very dry and arid. Deserts are also characterized by the absence of vegetation.
Castle and sculpture competitions
Although the first image that comes to mind when we hear about sand castles is our childhood on the beach, with plastic buckets and shovels, letting ourselves be carried away by our imagination and sketching simple structures that - in the best of cases - We received a series of compliments from our elders, there is an area of competition that has little to do with this children's team and takes place in various parts of the world.
The sand castle competitions number more than twenty and some of the sculptures are so impressive that when looking at their photographs many doubt their legitimacy: both due to their dimensions and the degree of detail , it is difficult to believe that someone is capable of achieve 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 rather they 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 Sun & Sea Festival , in Imperial Beach , California ( United States ). It started in the 1960s and little by little it became a true tradition of the place. Participants in each category, both adults and children, 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 visitors from various parts of the world.
An arena is a stadium or venue that can host sporting and artistic events.
Arena as an enclosure
Arena, on the other hand, is a term used to name the venue where different events take place. Boxing fights, basketball (basketball) games, concerts and other shows can be organized in the arena.
An example of this type of space is the Farmasi Arena , also called Arena Multiuso do Rio and formerly known as HSBC Arena , which is located in the Brazilian city of Rio de Janeiro and was used in the 2007 Pan American Games and the Olympic Games in 2016 among other competitions.
