Why does snow melt?

雪会融化，是因为太阳晒一晒，或者天气变暖的时候，冰就会变回水。

Xuě huì rónghuà, shì yīnwèi tàiyáng shài yí shài, huòzhě tiānqì biàn nuǎn de shíhou, bīng jiù huì biàn huí shuǐ.

雪是很多很多小冰晶做成的。太阳出来了，或者空气变暖的时候，这些冰就会慢慢变回水。所以雪会开始滴答滴答地化开，也会变得湿湿的、越来越小。

下雪天快变暖的时候，你觉得第一滴水会先从哪里出现呢？

Snow melts when sunshine or warmer air turns the ice back into water.

Snow is made of tiny ice crystals. When sunshine comes out or the air gets warmer, the ice starts turning back into water. That is why snow gets drippy, slushy, and smaller as the day goes on.

Where do you think the first drip would show up on a snowy day?
