morphostructure

Morphostructure, in geology, refers to the external structure of rocks and how they relate to the development of erosional forms and topographic features. It is a component of geomorphology, which is the study of the Earth's surface features and the processes that shape them. Geomorphology classifies, describes, and explains the origin of landforms.12

Structural geology, a related field, examines the geometric relationships of rocks and geologic features, ranging from microscopic crystal structures to large-scale mountain belts and plate boundaries. It distinguishes between primary structures formed during rock genesis and secondary structures resulting from later deformation, such as folding and faulting. These structures are influenced by processes like erosion, weathering, and tectonic activity, all of which contribute to the Earth's diverse topography.32
