高山比平地冷的原因很多。根据一股的情况来說,这是由于空气直接吸收太陽光的热量的能力比較差,而吸收地球表面上放出来的热量的能力比較强。但是地球表面上的热量主要也是从太陽來的,因此,空气吸收地球表面上的热量多少,也就間接同地球表面吸收太陽的热量多少有关系了。 There are many reasons why mountains are colder than plains. According to one case, this is due to the relatively poor ability of the air to directly absorb the heat of sunlight, and the ability to absorb the heat released on the surface of the earth is relatively strong. But the heat on the surface of the earth is mainly from the sun. Therefore, how much heat the air absorbs on the surface of the earth is indirectly related to how much heat the sun absorbs on the surface of the earth.
