Why is the temperature low in the mountains? Be careful not to copy and paste, and don't explain to me that the temperature drops by 6 degrees every time the altitude rises 1000 meters.

Both air and ground are substances, so both air and ground can absorb the heat of the sun. In other words, the temperature is not heated by the surface, but the air is directly heated by the sun. It's just that the density of the earth's surface is higher than that of air, which means that heat is concentrated and part of it becomes the temperature of air, but it has little effect on temperature, which does not affect the formation temperature of air directly irradiated by the sun. When the air density in high mountains is low, the heat density is not as high as that produced when the air density is high in flat land. And in the same big place, the surface area of the mountain is much larger than that of the plain, so the heat absorbed by the mountain surface is not as much as that absorbed by the plain surface, and the heat is not so concentrated, which has little effect on the temperature. That is to say, per unit space volume, because the air absorbed by solar heat in mountains is far less than that in plains, the temperature in mountains is lower. The surface of the snow-capped mountains converts sunlight that should be converted into heat energy into light energy before it is produced, which makes the temperature in the snow-capped mountains lower.
