I
  • The external geomorphological changes vs. the internal geomorphological changes: paces and examples.
  • The Sun and the gravity as the causes behind the external geomorphological agents. The water cycle as an example.

  • Chemical weathering.
  • Geomorphological action of the changes of temperature. Freeze-thaw weathering.
  • Geomorphological action of the wind. Occurrence, aeolian landscapes.
  • Geomorphological action of the superficial continental waters. Types of superficial continental bodies. The geomorphological processes in the sections of a river. Glacial vs. fluvial landscapes.
  • Geomorphological action of the subterranean continental waters. Karstic landscapes.
  • Geomorphological action of the sea. Seawater movements. Landscapes carved by the sea movements.
  • The formation of soils.
