This is because the top of the troposphere is normally very cold, causing ascending water vapour to freeze into ice crystals that drift and fall, rather than continuing up into the stratosphere.
这是因为对流层的顶端通常极其寒冷，上升的水蒸汽凝结成飘落而下的冰晶，而没有继续上升进入平流层。
Clouds form when humid air cools enough for water vapor to condense into droplets or ice crystals.
当潮湿空气遇冷降至一定温度时，其中包含的水蒸气便聚集成小水滴或小冰晶，它们组成了云。

应用于冰淇淋中，使水、脂肪、蛋白质等形成均匀、分散、稳定的混合物并能避免冰晶的出现，同时口感细腻、滑润形成性好。
Snow is a form of frozen water. It contains many groups of tiny ice particles called snow crystals. These crystals grow from water particles in cold clouds.
雪是由冻水形成，包含大量细小冰粒的冻水被称作雪晶，这些晶体由寒冷云层中的小水滴形成。
Water gushes from Charon 's deep interior, spewing forth in icy volcanoes, the "lava" freezing instantly into tiny ice crystals and snowing down to the moon's surface.
水从喀戎内部被挤出，以冰火山的形式向外喷撒，“熔岩”立即被冻结成微小的冰晶像雪一样落到这个月亮表面。
For example, slow freezing leads to the formation of larger ice crystals. This results in relatively large voids, which aid in the escape of water vapor during sublimation.
例如，缓慢冷冻造成较大的冰晶排列，造成冰晶升华时有较大的逃逸通道。
Fact: clouds, which consist of water droplets and ice crystals, seem to hover in the air.
事实：云，由小水滴，冰晶，好像在空中盘旋。
