Is an isthmus a constructive force?

Answer 1

An isthmus itself is not considered a constructive geological force; rather, it is a landform that typically forms as a result of tectonic activity, sediment deposition, or erosion. Constructive forces in geology generally refer to processes that create new landforms, such as volcanic eruptions or the accumulation of sediment. An isthmus can be seen as a feature resulting from these processes rather than a force that actively creates land.
