When water is heated, it turns into vapor. It goes up with the air.The air can hold some vapor at some temperature. When the air goes up and becomes cooler and cooler, it cannot hold so much vapor. Then vapor becomes water. When water falls from the sky, it's called "rain". After it rains, it becomes water again.。

2. 雨是怎么形成的,用英文解释4到5个句子,太深奥的不需要,谢谢大家

1,Rain is formed when water molecules in the air collect around particles of dust.

雨是由于空气的水分子聚集在灰尘的四周而形成的。

2,The water evaporated to form clouds. These rose ihto the sky to form rain.

水蒸发形成云，云上升到空中形成雨。

3, water vapor could be much less likely to turn to rain without the dust particles.

假如没有灰尘的微粒，水蒸气就不大可能形成雨。

4,When the collected water becomes heavy enough the water droplet falls to the earth as rain.

水气凝结到一定程度就形成了小水滴，其重量足以使它落到地上，即为雨。

3. 雨的形成过程 用英文表达,不少于六十个词

Rain is falling from the cloud droplets, water, land and ocean surface evaporates into steam, cold water vapor rises to a certain height into small droplets, the droplets form a cloud, they are each in the clouds collision, into large droplets into the air when it is large when asked live on Falling down from the clouds to form rain.

雨是从云中降落的水滴，陆地和海洋表面的水蒸发变成水蒸气，水蒸气上升到一定高度后遇冷变成小水滴，这些小水滴组成了云，它们在云里互相碰撞，合并成大水滴，当它大到空气托不住的时候，就从云中落了下来，形成了雨

4. 怎样变成雨用英语来表达

the heat of the sun evaporates the water from the ocaens,seas,rivers and lakes. water vapor is thus formed.this rises and forms clouds in the air.

As the air rises,it is cooled.The higer it rise the more they are colled.this cause more and more water vapor to condense.In this way,the tiny drops of water in the clouds get bigger and bigger until then are heavy enough to fall to the earth as rain.

5. 雨是怎么形成的英语作文5句

In the water in the clouds, the cloud drop all is the small waterdrop。

They mainly are depend on continue to congeal with mutually collidecombine increase。 Therefore, in Shui Yunli, the cloud drop mustincrease to the raindrop size, first needs the cloud very thick, clouddrop thick, the water content are many, like this, it can continue tocongeal the growth; Next, also needs to have a stronger verticalmovement in Shui Yunnei, like this can increase the opportunity whichthe multiple collision combines。

But in quite is thin and the quitestable water in the clouds, the cloud drop not enough congeals andcombines the growth opportunity, only can cause, the cloudy daycloudy, the congress does not rain。 In each kind of different cloud, its cloud drop size distribution isvarious, creates the cloud drop size uneven reason is in thesurrounding air the water vapor shift as well as cloud dropevaporating。

Causes the factor which the cloud drop grows is congealsthe process and the collision and with the process, in only has thecondensation in the situation, the cloud drop size is even, but as aresult of the water vapor supplement, enable certain cloud drops tohave the growth, in addition and with the function result, causes thebigger cloud drop to continue to grow changes accomplishes for theraindrop。 The raindrop drops the earth's attraction function, when hasthe ascendant current, can have an upward strength to add on theraindrop, causes its drop the speed to slow down, and some smallraindrop possibly are also brought to come up。

Only has when theraindrop increases to the certain degree, can drop the ground, formsrains。

6. 水变成雨的过程

地球上的水受到太阳光的照射之后，就变成水蒸气被蒸发到空气中去了。水蒸气在高空遇到冷空气便凝聚成小水滴。这些小水滴都很小，直径只有0.0001~0.0002毫米，最大也只有0.002毫米。它们又小又轻，被空气中的上升气流托在空中。就是这些小水滴在空中聚成了云。

空气中的水蒸气在高空寒冷环境受冷凝结成小水点或小冰晶，小水点或小冰晶相互碰撞、并合，变得越来越大，大到空气托不住的时候便会降落下来，当低空温度高于0℃时，便是雨。

由液态水滴（包括过冷却水滴）所组成的云体称为水成云。

水成云内如果具备了云滴增大为雨滴的条件，并使雨滴具有一定的下降速度，这时降落下来的就是雨或毛毛雨。由冰晶组成的云体称为冰成云，而由水滴（主要是过冷却水滴）和冰晶共同组成的云称为混合云。从冰成云或混合云中降下的冰晶或雪花，下落到0℃以上的气层内，融化以后也成为雨滴下落到地面，形成降雨。

7. 介绍雨是怎么样形成的.5个句子以上

雨形成的基本过程是：空气中的水蒸气在高空受冷凝结成小

水点或小冰晶，小水点或小冰晶相互碰撞、并合，变得越来

越大，大到空气托不住的时候便会降落下来，当低空温度高于O℃时，便是雨。

由液态水滴（包括过冷却水滴）所组成的云体称为水成云。

水成

云内如果具备了云滴增大为雨滴的条件，并使雨滴具有一定

的下降速度，这时降落下来的就是雨或毛毛雨。由冰晶组成的云体称为冰成云，而由水滴（主要是过冷却水滴）

和冰晶共同

组成的云称为混合云。从冰成云或混合云中降下的冰晶或雪花，下落到0℃以上的气层内，

融化以后也成为雨滴下落到地面，形成降雨。

在雨的形成过程中，大水滴起着重要的作用。当水滴半径增大到2—3mm

时，水分子间的引力难以维持这样大的水滴，

在降落途中，就很容易受气流的冲击而分裂，通过“连锁反应”

使大水滴下降，小水滴继续存在，形成新的大水滴。这是上升气流较强的水成云和混合云中形成雨的重要原因。
