You çanions are ways of relief very interesting, as they form deep valleys, that is, an area of very low altitude that is surrounded by areas higher than it. They extend over very wide areas and form beautiful landscapes, those breathtaking, with great precipices and, in some places, veritable gigantic walls!
The best known and most visited canyon by tourists around the world is the Grand Canyon, located in the United States (pictured above). However, there are geological formations of this type located in the most diverse parts of the planet, including the Brazilian territory, which has canyons such as Itaimbezinho, in Rio Grande do Sul; the Devil's Throat, on the Iguaçu River (Paraná), and many others.
But do you know how canyons form?
They are formed from a slow and gradual process, those that take millions and millions of years to constitute itself in fact, so that it is not possible to perceive its transformation process instantly. Briefly, they arise from the wear of inclined relief forms, which is caused by the action rainwater and rivers mainly, as well as by winds and also by variations in the climate.
These elements are called external relief transformation agentsand are responsible for transforming rocks and landforms in general. It's as if they were shaped by nature over time, in a light and subtle way, giving rise to beautiful landscapes.
The canyon landscapes are sometimes so imposing that they make us realize how small we are in the face of the grandeur of natural forms. Some of its canyons have falls of up to 5,000 meters high! Anyone who looks at this striking appearance does not even imagine that this form of relief is formed so slowly and gradually...
