Landforms
Landforms are the physical expression of the land surface. The principal groups of
landforms are plains or plateaus, hills, and mountains. Within each of these groups are
surface features of a smaller size, such as flat lowlands and valleys. Each type results
from the interaction of earth processes in a region with given climate and rock conditions.
A complete study of a landform includes determination of its size, shape, arrangement,
surface configuration, and relationship to the surrounding area.
