Building and Education
Three stones consist of three large groups of rocks, as well as a number of smaller individual blocks. Rocks are dotted with numerous cracks, there are also blowing boilers , as well as other manifestations of weathering and other geological and geomorphological phenomena. Cracks in granite divide the rock mass into separate blocks of a rounded cubic shape, expanding when approaching the surface [2] .
The formation of such a rock mass is associated with weathering processes. In past geological epochs, when the climate in Central Europe was warmer and wetter, granite was subjected to chemical weathering, which led to the formation of gres , whose properties are similar to gravel or sand, several meters deep. Further propagation of weathering along the cracks led to the formation of granite blocks of regular cubic shape. Later, in the process of climate change, the wood is removed under the influence of denudation processes , exposing the rock. Currently, the effect of weathering processes, mainly frosty, on the rocks continues, resulting in the destruction of rock with the formation of crushed stone [3] .
In art
Rocks are captured in the picture of the romantic artist Karl Karus “Three stones in the Giant Mountains” [4] .
