Definition of Valle

Depression of the terrestrial surface that manifests between two slopes inclined and elongated towards a sea, lake or endorheic basin

Valle Valley is called that depression of the earth's surface that manifests between two slopes inclined and elongated towards a sea, lake or endorheic basin , through which the waters of a river or the ice of a glacier generally pass, failing . Among the main causes of its original formation are: river erosion or mechanical weathering .

Most common types of valleys

There are different types of valleys, in which different geographical contingencies will have a lot to do when determining and differentiating them.

In a young relief, the valleys in V generally predominate , which are characterized by their slopes little modeled by erosion and that converge on a very, very narrow bottom.

On the other hand, when the state of erosion is really advanced, the so-called alluvial valleys originate, which have a flat and broad bottom, constituted by alluvial deposits between which the passage of water oscillates and oscillates.

Then we can find the U-valleys , which are a direct consequence of the glaciers. They have very steep walls and the bottom is concave . Within this type, it can be that when an ancient glacier recedes, the bed of one of its tributaries is at a height well above it and then at the end of its slope it will form waterfalls.

The dead Valley or also popularly known as a decapitated river (because it no longer has a watercourse) occurs when a river is captured by another, or when its bed has been closed by a mountain range or other reservoir.

Meanwhile, the blind valleys , originating from the karst lands, that is, the product of the chemical weathering of certain rocks, are those that do not have a natural exit and are closed by a counterpart, then, the waters that circulate through it on the ground and will continue their course through an underground network.

And the Endorheic Valleys , very common in those most arid areas, take place because the rivers cannot leave their river basins running through these types of valleys.

Famous valleys

Among the most famous valleys that can be found in the world geography are the following: Death Valley, Grand Canyon, Loire Valley, Napa Valley, Nile Valley, Mexico Valley, Ebro Valley, Danube Valley and Central Valley of California , among others.

Places on the planet that are characterized by having a formidable landscape beauty

But beyond the strictly geographical we were explaining in detail above lines we must say that the valley is not only that, an accident of world geography, but that the valleys are also places on our planet that are characterized by having a formidable landscape beauty and what causes those who visit them a tremendous admiration for the singularities of the land. The natural environment that accompanies them should also be highlighted because it adds to that beautiful visual and postal that they provide us and because in regards to their value they are certainly a determining element. Many of the valleys have animals and native flora that distinguishes them and that marvelously accompanies the unique geography they display.

Favorite places for tourists who love nature

For these questions we mentioned is that the valleys turn out to be places that are in high demand for tourism that likes to be close to nature and that delights with the mere contemplation of a beautiful landscape.

Those who love nature and hiking in a natural way usually choose the valleys as their destination.

Take care of the natural environment of the valley

Meanwhile, because of the importance they have on a natural level and also in the tourist demand of a nation, it is very important that the valleys are taken care of and protected. Many of them are located in National Parks that enjoy the protection of the state, but of course, it is not always enough and it is important to raise awareness in those who live there, and in visitors of course, so that they contribute to their care and not damage with an inconsiderate and unnatural action.

Other uses of the term

In other things, we must mention that the word valley has other uses in our expression , valley of tears, which is used with the mission of referring that this or that person is flooded by sadness and crying as consequence of having suffered a situation that caused a lot of pain.
