雲彩顏色國中英語作文

Sometimes the sky is full of white clouds. But sometimes clouds look black. Where does the colour come from?

Clouds are made of water or ice. But the drops of water in the clouds are not red or orange. The sun makes the colours in the clouds. Sunshine changes colour as it goes through the drops of water in the clouds.

Clouds look dark because they are so thick. Lots of drops of water make a cloud. Very little sunshine can go through. Dust also makes clouds dark. Dust from the ground is blown into the sky. and becomes part of the clouds.

The colours of the clouds tell about the wether.

有時天空佈滿了白雲，可是有時雲看起來是黑的。這些顏色是從哪裏來的呢?

雲是由水和冰組成的。可是雲中的`水滴並不是紅色或橘黃的。太陽使雲有了顏色。當陽光穿過雲中的水滴是改變了顏色。

雲看起來暗是因為雲層太厚了。許多水滴組成了雲，很少的陽光能穿透雲層。塵埃也能使雲變暗。地面上的塵埃被吹到空中時，它就成了雲的一部分。

通過雲彩的顏色能預報天氣。
