sisävuoria

Sisävuoria is a Finnish term that can be translated as “inner mountains.” It is generally a descriptive phrase rather than a formal geological category, used to refer to mountainous or highland regions located inland, away from coastlines or political borders. The term is more common in regional geography, travel writing, or historical descriptions than in strict scientific classifications.

Etymology and usage: sisävuori combines sisä- meaning internal or inland with vuori meaning mountain. The plural form is sisävuoria. In usage, the expression emphasizes the interior location of the range or highland area and is often employed to contrast inland topography with coastal or frontier mountain systems. It does not correspond to a specific tectonic or mineralogical class.

Geology and geomorphology: inland mountains can arise from various processes, including intracontinental uplift, remnants of ancient orogenic belts, and long-term erosion that concentrates high terrain away from coastlines. Such regions may feature old, resistant bedrock, plateaus, ridges, and deep valleys. Climate influences and drainage patterns in interior areas can differ from adjacent lowlands, shaping distinctive ecosystems.

Distribution and examples: there is no universal set of ranges referred to as sisävuoria; the term is context-dependent and may be used differently in different languages or regions. In Finland, real, high mountain terrain is limited, so sisävuoria would typically describe inland highlands or uplands in descriptive texts rather than a specific mountain system.
