Respuesta :

The answer is A It constantly raises the bed of the river

The correct option is: "It constantly raises the bed of the rivers. "

It is formed by deposits of silt originated by the deposition of particles with sizes ranging from 10 to 50 micrometers and which are transported by dust storms over thousands of years. It is yellowish in color and lacks stratification. It consists mainly of silicates (quartz, feldspar, etc.), calcium carbonate (from limestone, dolomite, etc.), very fine organic and mineral detritus from the group of clays. It constitutes a very fertile and deep labor soil.
