They can also be artificially created through human activities, such as the construction of levees or dams. Regardless of their origin, flood plains play an important role in regulating water flow and supporting ecosystems.

The rheology of the layers being folded determines characteristic features of the folds that are measured in the field. Rocks that deform more easily form many short-wavelength, high-amplitude folds. Rocks that do not deform as easily form long-wavelength, low-amplitude folds. china\u0027s browserWebFold mountains. Zagros Mountains, seen from space.

This type of structure is visible on a seismic section, but, as seismic sections are normally ‘time sections’, the actual structure may be obscured by velocity changes above the anticline. china\\u0027s browserWebA fold is a bending of the rocks of the earth’s crust. It is structured in the form of waves, successive. As such some of the features of the folds correspond to a wave either. Rock layers in Folds.
