Rain falls when water vapour in clouds condenses (凝结). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, ...

acondensation: the change of gas or vapor to a liquid;either by cooling or being subjected to increased pressure.When water vapor cools in the atmosphere,for example,it condenses into tiny drops of water,which forms clouds. 结露: 气体或蒸气的变动对液体; 通过冷却或被服从到增加的压力。例如时...
Anyway, snowflakes have a particular form: there's a six-sided center, with six branches or arms that radiate out from it. But how did they get that way? Well, you start with water vapor. You need a pretty humid atmosphere. And that water vapor condenses directly into ice, into an ...

Clouds & Precipitation Notes/Vocabulary How do clouds form? when warm air & cold air meet, cold air pushes up the warm air and a cloud can form when air rises and cools, the water vapor in the air condenses into tiny water droplets and forms a cloud If the temperature...
