Physiographic regions of the world
CLASSIFICATION SYSTEM FOR EARTH'S LANDFORMS BASED ON THE WORK ON N. M. FENNEMAN
Physiographic section; Physiographic regions of the world; Physiographical region
Physiographic regions of the world are a means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections.
