It’s a sunny day 。The water in the river is very hot ， and becomes the vapour 。 The vapour goes up together ， and becomes the cloud 。
When the cloud is heavy 。 They become the rain。 The rain fall down into the lake ， sea ， river and stream。
The sun comes out 。 The water in the river become the vapour again 。
