In spite the surface of the earth seems to us be static and seemingly unalterable, external factors are eternally worked, a lot of times in steps almost imperceptible, for the renewal of the soil that surround us.

   AS the constant flow of the sea or of some river, as the wind that comes in breeze or windstorm form , as the own human being enlarging your world in the form of excavations, constructions, opening of highways or changing course of rivers, a world of matter movements exists to our turn, that combined or separately, alter the surface of the planet that we inhabited continually.

    Due we have not many works of easy access to the interested ones on those changes that happened or happen inside of our municipal district, we intend in that page to locate for maps and try to show with images, the more significantthat that we have inside of that subject.o.

For a better view of the subject, we will begin informing the basic notions on the municipal district.
