The change in temperature between day and night, between winter and summer: is the element which changes the volume of the mineral. The coefficient of the minerals are very different, even in a mineral well Expander long axis is greater than the short axis. So, the stone gets hot or cold Vulture repository is created causes micro fissure border contact between mineral particles, the rift between the particles will meet the great fissure and fissure formation and form a large fissure network than the naked eye can see. Gradually thanks to groundwater, or surface water due to water freezing on the rift (temperate climates and subtropical South Korea) makes the rift is wide open and then break the stone blocks to turn architecture into individual chips beads. That process easily noticed in the harsh climates such as Central Asia and the neighbouring mountain desert. The day the Sun is intense, heated stones can heat up to 70-80 degrees Celsius, cold night can duplex down below 10 degrees Celsius, even at the stones are hot summer noon again encounter the Rainshower suddenly make them may be chapped and peeling away each layer
