赤道上，为什么也有雪山？

Kilimanjaro stands right on the equator. 乞力马扎罗山就在赤道旁。 But the top of the mountain is freezing. 可山顶上却冷得要命。 The higher you climb, the colder it gets. 爬得越高，天气越冷。 So snow stays on the top all year. 所以山顶一年四季都有雪。 Green forests sit below, white snow above. 山下是绿森林，山顶是白雪。 That is really a strange sight. 这样的景色真的很奇妙。
