Trzy Korony
Trzy Korony is the summit of the Three Crowns Massif, an independent portion of a range called Pieniny Mountains in the south of Poland. Trzy Korony forms the central part of a compact group of connected mountains known as Pieniny Środkowe, consisting mainly of the limestone and dolomite rock strata...

Massif
In geology, a massif is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole...

Erosion
Erosion is when materials are removed from the surface and changed into something else. It only works by hydraulic actions and transport of solids in the natural environment, and leads to the deposition of these materials elsewhere...
