Common natural phenomena in life: rainbows after rain, static electricity in life, solar eclipses.
1. The rainbow phenomenon appears after the rain
After the heavy rain, a beautiful rainbow appeared in the sky, the seven-colored rainbow bridge, and how many colorful childhood dreams were built. In fact, the rainbow is an optical phenomenon, after a heavy rain, due to the high temperature of the ground, the rain evaporates to form water vapor, and the small water droplets of the air species meet the irradiation of the sun, causing dispersion and reflection to form a rainbow bridge, which is the rainbow we see.
2. Static electricity in life
In autumn and winter, the weather is dry and dry, and in the dark night, when you take off your sweater, you will make a "crackling" sound and you can see "sparks"; When touching the plastic balls in the Science and Technology Museum, human hair will stand on end; When playing with the plastic tube slide, the hair will also stand on end. This phenomenon is called electrostatic electricity, which is caused by friction causing electrons to transfer from one object to another, breaking the balance of electric charge and generating static electricity.
3. The phenomenon of solar eclipses
The sky was clear, the sun was shining, there was no lightning and no thunder, the sky suddenly went black, and the earth instantly turned into night. This is a typical solar eclipse phenomenon, which is when the moon moves between the sun and the earth, if the three are exactly in a straight line, the moon will block the light of the sun to the earth, and the black shadow behind the moon will fall on the earth, and the solar eclipse phenomenon will occur.

At dawn, the filial snow dolls slept peacefully in the arms of Mother Earth, and they spread a thick quilt on Mother Earth, for fear that Mother would freeze. The snow was still falling, and I reached out and caught a little white elf, and looked at it carefully: six small crystal clear feet, with thin little hands on them, and in the center of it, there was a bright little eye, looking at me very intently.
After a while, the naughty snow doll turned into a water doll and "slipped away" through my fingers, how amazing it was! The snow finally stopped, and they fell asleep quietly in Mother Earth's arms. ...... on the pine trees, on the car wash, on the roofIt's full of snow dolls that have long been asleep, and they are tired, so don't wake them.
After a busy night, the whole of Nanjing was dyed white by them, and we seemed to have entered another world - the world of snow, but also a magical and beautiful world - the world of white.
Snow always comes silently and goes silently.

2. In the hot summer, the home air conditioner is dripping from the exterior wall of the air conditioner.
Explanation: Water vapor in the air condenses into water droplets when cold. The cold side of the air conditioner absorbs the heat of water vapor in the indoor air.
3. In the hot summer, white clouds float in the blue sky.
Explanation: Water vapor in the air condenses into small droplets when cold. When a cloud of hot air rises, the water vapor in the air will condense into small droplets, which will be suspended in the sky and become clouds.
4. In the hot summer, there are white clouds floating in the blue sky, and it will rain after a while.
Explanation: The water vapor in the air is condensed into small water droplets when it is cold, suspended in the air into clouds, and when the clouds are getting bigger and bigger, the small water droplets become large water droplets and fall down is rain.

8. On the day of resurgence, open the windows for ventilation, and there will be more and more water on the walls and ground on the first floor.
9. In winter, it was rainy for many days, the cold wind blew, and it snowed after a while.

10. In the cold winter, there is ice and snow on the road, and workers sprinkle salt to melt ice and snow.
Explanation: Water condenses into ice and snow at zero degrees, and when a small amount of salt is added, the freezing point of the water drops, and the ice and snow melt into water.
