Water vapour condenses to form clouds

水蒸气凝结形成云。

The air near the surface of the earth is warmer than that which is higher up, so when the water-vapour rises very high above the ground, it is cooled.

靠近地球表面的空气温度比高空的空气温度要高一些，因此，当水蒸气漂浮到高空时就会被冷却。

So the water-vapour is first changed into those very tiny specks of liquid water which have been called water-dust, and appears as clouds; and then these specks of water join together to form drops of rain.

因此，水蒸气首先变成了非常细小的水粒——也就是我们所说的水雾——并构成了云朵，然后这些水粒汇聚在一起成为了雨滴。

We have learned that when water-vapour is cooled it is condensed.

我们知道，水蒸气遇冷之后就会产生冷凝。

So when this vapour is changed back into water again, it forms pure fresh water.

因此，当水蒸气再次变成水滴的时候，淡水应运而生。

"And whether you're a river or vapor, your nature never changes."
