Final answer:
Geographically, land is divided by physiographic provinces such as the Rocky Mountains and the Intermontane Basins and Range. These regions have characteristic landforms and are detailed on maps, which also delineate political units like cities and countries.
Step-by-step explanation:
The land area is divided geographically by physiographic provinces. Canada and the United States are notable examples where the division into distinct landforms can be very clear. These physiographic provinces consist of regions with characteristic geomorphology, often linked to specific types of subsurface rock or structural elements. For example, on the western part of the North American continent, we find divisions such as the Rocky Mountains, Pacific Mountains, the Valley and Ridge Geologic Province, the Intermontane Basins and Range, and the Plateaus that lie in between.
To understand these divisions further, one can utilize skills like WG.13A, which involves interpreting maps to explain the division of land into separate political units such as cities, states, or countries. This encompasses both man-made and natural borders, providing a comprehensive understanding of how land areas are segmented geographically and politically.
