A cloud is a collection of water droplets or gas or ice crystal colloids that remain in the atmosphere. The www.biquge.info clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the fine dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. In addition, clouds can take on a variety of shapes, and they are divided into many types depending on the height and shape of the sky.

Clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the fine dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. Because clouds reflect and scatter electromagnetic waves in all bands, clouds are grayscale in color, white when they are thin, but they can appear gray or black when they become too thick or dense for sunlight to pass through.

Planets other than Earth can also have clouds, but water is not necessarily the main component of clouds on other planets, such as the sulfuric acid clouds of Venus.

The water on the ground absorbs heat and turns into water vapor, which rises to the upper layer of the sky vapor. Due to the low temperature of the upper layer of the vapor layer, the volume of water vapor decreases, the specific gravity increases, and the steam decreases. Due to the high temperature below the vapor layer, it absorbs heat during the descent process, rises again and cools again, and then descends, so that the gas molecules gradually shrink and finally concentrate at the bottom of the vapor layer. A low temperature zone is formed at the bottom layer, and water vapor is concentrated in the low temperature zone, which forms a cloud.

The sky was full of clouds of different colors, some white as flocculent, some as black as black, some gray as grey, and some as red and purple. Here, the thickness of the clouds determines the color, and the thickness of the various clouds we see varies greatly, with a thickness of up to 7-8 kilometers and a thin one of only a few tens of meters. There are many types of stratiform clouds, solitary cumulinary clouds, and undulating clouds. Very thick stratiform clouds, or cumulonimbus clouds, where the light of the sun and moon is difficult to penetrate, and the clouds appear very dark; Slightly thinner stratiform and undulating clouds, which appear gray, especially undulating clouds, with more grayish colors at the edges of the clouds; Very thin clouds, light is easy to pass through, especially thin clouds composed of ice crystals, the filaments appear particularly bright in the sun, with a silky luster, even if there are such stratiform clouds in the sky, ground objects will still reflect shadows in the light of the sun and the moon. Sometimes the clouds are so thin that they are barely visible, but as long as one or several large rings are found near the sun and moon, it can still be concluded that there are clouds, which are called "cirrostratus clouds". Isolated cumulonial clouds, which appear to be white because of the thicker cloud layer and the sunny side, where the light is almost entirely reflected; On the backlit side and its bottom, the light is not easy to transmit through, and it looks grayish and black. At sunrise and sunset, because the sun's rays are obliquely shining through the thick atmosphere, the air molecules, water vapor and impurities scatter a large number of short-wave parts. However, the red and orange long-wave parts are not scattered much, so when they reach the lower atmosphere, the long-wave light, especially the red light, accounts for the absolute majority, and not only the sky in the sunrise and sunset directions is red, but even the bottom and edges of the clouds illuminated by it also turn red. Because the clouds are composed of water droplets, ice crystals, and a mixture of the two, the light of the sun and the moon can also cause all kinds of beautiful halos or rainbows when they pass through. --------introduction

As soon as the wind took a step, he saw Yin Shan shoot out a fist light in mid-air, the fist light was like a spirit snake spitting letters, but it was extremely fierce, and the two fist lights were like two steel dart guns, and they were extremely fierce and directly inserted into the head of the Track Cloud Lifeform No. 2.

"Whoop,,,," Blood gushed everywhere, and the head of Track Cloud Lifeform No. 2 was fiercely poked by the fist light into two irreparable holes, and fell to the ground in an instant, rolling his eyes, and died.

The 200,000 Track Cloud Lifeform Super Strength was actually solved by her move.

It's too tough! The wind was very shocked, and watched the Track Cloud Lifeform No. 2 fall, Yin Shan drifted in the air, with an angry face, like a child who was disturbed by Yaxing, and looked very unhappy.

The Track Cloud No. 2 lifeform died, lying under Yin Shan's feet, Yin Shan instantly burst out with a fist light, and hit it hard again, as if she was venting.

"It's too bloody, isn't it?"

Shan Liankong, Xiyue, and Fog looked at everything dumbfounded, and Feng couldn't believe it, is this still the girl who has just started without any skills? It's like two people, violent like a demon who kills people without blinking. It's no wonder that a woman's heart is a needle, this is simply a beautiful appearance, a violent heart.

Yin Shan returned to the wind, looked at the Track Cloud No. 2 lifeform lying in a pool of blood and convulsed, and coldly burst out, "It's too bloody, it's so cruel." The wind looked at her again as if it were a monster.

Solving the track cloud life form No. 2 has a certain deterrent effect on the surrounding small track clouds, because Yin Shan's violent stunned just now scared some small track clouds back several feet away, Yin Shan glanced around with satisfaction, and grinned: "It's okay." ”

Yin Shan's feat just now, now all the Track Cloud lifeforms dare not approach Yin Shan, so everyone doesn't have to worry about Yin Shan's safety.

On the contrary, the wind is a bit bitter. Although the twenty or thirty thousand level track clouds are intellectually low, they also know how to pick soft persimmons and pinch them, Yin Shan is like a spicy hand fairy, fierce and ruthless, they are afraid, but they are all about the wind, and many track clouds bypass Yin Shan and rush straight at him. More than a dozen tracking clouds attacked him, the wind was calm, and he was careful to deal with it, but he would still be attacked from time to time, and just a 300,000-level tracking cloud No. 1 lifeform scratched his back fiercely, his clothes were torn instantly, and three paw prints were exposed on his back, and blood flowed from the wound.

The thigh was also bitten hard by a small track cloud, but fortunately it was not poisonous, otherwise it would not be able to support it.

"Hey, you can't do it, do you want me to save you." Yin Shan looked at the wind surrounded by the track clouds, worried, looked at his back, blood seeped out of his thighs, and he couldn't help but be scared, and his fists became more aggressive, constantly approaching like the wind. The more aggressive her means, the greater the pressure on the wind's side, and the surrounding track clouds all gathered around, all of them surrounded by the wind, and the fog, Xiyue and Shan Liankong were almost isolated by a part of the small track clouds, so they couldn't have time to rescue in time.

The smell of blood stimulated their brains, and their eyes completely changed, revealing their primitive ferocity, which was bound to tear the wind apart.

Wind: "You just take care of yourself." ”

Although the wind is a robot puppet, it is also exactly the same as the silver tree simulation human, so the wind will also bleed, and if he runs out of blood, he will also die like an ordinary human.
