How do rainbows form?

Rainbows are caused by the dispersion and reflection of small spherical water droplets when sunlight shines into the air When sunlight enters the water drop, it will enter at different angles at the same time, and reflect at different angles in the water drop Among them, the reflection of 40 to 42 degrees is the strongest, resulting in the rainbow we see When this reflection is caused, the ...

How does rain form?

Rain is a natural precipitation phenomenon, which is produced by atmospheric circulation disturbance When the water on the earth is irradiated by the sunlight, it becomes water vapor, which is evaporated into the air When the water vapor meets the cold air at high altitude, it condenses into small water droplets These small water droplets are very small, with a diameter of only 0 01 ~ 0 02 m ...

How does the wind form?

Wind is an air flow phenomenon on the earth, which is generally caused by solar radiant heat Sunlight shines on the earth& 39;s surface, raising the temperature of the earth& 39;s surface, and the heated expansion of the air on the earth& 39;s surface becomes lighter and rises After the hot air rises, the low-temperature cold air flows laterally, and the rising air falls due to the gradual cooling and weighting Due to the high surface temperature, it will heat the air to rise This kind of air flow is wind ...
