Relationship between Yin and Yang and Landscape
The mountain is a towering part of the ground, and the light energy of the sun rising in the east and setting in the west can reach the south of the mountain, but not the north, so the south of the mountain is sunny and the north of the mountain is cloudy.
The water in the south of the mountain is called Yang, and the water in the north of the mountain is called Yin. In the field of feng shui, the so-called mountain refers to sitting on the mountain, and the so-called water refers to the direction; It means sitting south facing north is the sun; It's cloudy sitting facing south.
Snow on the mountain:
In the north of the mountain, perennial snow means that there is perennial snow or permanent semi-permafrost in this area. Most of them are located at the top of the mountain, at the North Pole and the South Pole. The mountains are high in altitude and the air is thin. Although the solar radiation is strong, the ground reflection is also strong. At the same time, due to the lack of heat preservation effect of water vapor and carbon dioxide, the ground radiation loss is very small, so the temperature is very low.
Every time the average altitude rises 1 km, the temperature drops by 6 degrees. When the altitude of the mountain is high and the temperature at the top of the mountain is below 0 degrees, the snow on the top of the mountain will not melt. If it is below 0 degrees all the year round, mountain glaciers will form and will not melt all the year round.
