Who knows that scientific knowledge explains wonderful natural phenomena, at least 2, tell me quickl

A rainbow is an optical phenomenon in meteorology. When sunlight hits raindrops in mid-air, the rays are refracted and reflected, forming an arched spectrum of colors across the sky. The rainbow of colorful colors, from the outside to the inside, are:

Red, orange, yellow, green, blue, indigo, purple.

Rainbow is a natural phenomenon caused by the reflection and refraction of light from sunlight into water droplets in the air.

Meteors are tiny objects and dust particles distributed in interstellar space, called meteoroids. They fly into the earth's atmosphere, rub against the atmosphere to generate light and heat, and finally burn up into a beam of light, a phenomenon called a meteor. (If it doesn't burn out, it's a meteorite).

The water freezes at 0°, and the temperature in the Arctic drops below 0°C, but there is water, which is due to the salt content in the seawater.

Tides arise due to the gravitational pull of the moon and the sun acting simultaneously on the water on the earth's surface.

Mirage – multi-specular reflection.

Dew -- condensation.

Too much.

10. Easter Island Stone Statue.

Easter Island is a small island in Chile. When people think of Easter Island, the first thing that comes to mind is the more than 600 stone statues of giants that stand on the island. The stone statues on Easter Island are carved from a single block of dark red igneous rock, which is generally 7,10 meters high and weighs 30,90 tons.

How people at that time carried these statues remains a mystery to this day.

11. Bermuda's Mysterious Triangle.

Located in the western part of the North Atlantic, the Bermuda Triangle is an archipelago of 7 large islands and about 150 smaller islands, as well as a number of reefs. Here, advanced instruments will fail, and there is no chance of survival if personnel are in distress. Some scientists have proposed that when natural disasters such as **, storms, and volcanic eruptions occur, infrasound waves that cannot be heard by the human ear but have great destructive power will be generated.

When an oscillation frequency of 7 Hz is placed, the human heart and nervous system are paralyzed. Infrasound may be the culprit behind the tragedy here.

12. A strange stone that can "tell the time".

In the vast desert southwest of Alis, central Australia, there is a strange stone that can "tell the time". Standing in the desert, this strange rock is 348 meters high and has a circumference of about 8,000 meters, and its exposed part of the ground alone may weigh hundreds of millions of tons. This strange stone changes color very regularly every day:

When the sun rises, it is brown; At noon, when the sun is scorching, it is grayish-blue; In the evening, when the sun sets, it turns red.

1. The chameleon's ** can change accordingly with the change of the surrounding environmental color.

2. The electric eel is also amazing enough to generate electricity. There are also octopuses that can hypnotize other fish and prey.

3. Male seahorses give birth to babies.

4. Mermaids, Loch Ness sea monsters, snowmen, wild men, etc.

5. Cats' eyes can see things at night, but people can't; A dog's nose is very sensitive, and people can't compare to it.

6. The female praying mantis should eat the male praying mantis after marriage.

7. Ants can transmit information by touching their antennae.

8. The gecko breaks off its tail and escapes; The starfish threw out their entrails and fled; Earthworms are still alive when they are broken.

9. Man-eating butterflies and man-eating ants.

10. Ultrasound of bats; The frog's breath.

11. Magical auroras, thunderstorms, red tides, ice circles, milky clouds.

Nature like a magical bai movie

My calf has three legs.

The elephant and the ant got married, and within two days the elephant died. The ant cried very sadly, and while crying, he said, "Why did you die in front of me?" Then I don't have to do anything in this life, I'll bury you.

l. There will be a rainbow after the rain.

2. The shape of the leaves is varied.

3. Stars blink.

4. Flowers are colorful.

5. There are shells on the stones.

6. Spiders, ants, cicadas. You will know that it will rain.

Swallows fly low: Swallows feed on small insects, before rain, the air pressure is low, the air humidity is high, and the wings of insects become heavy due to water vapor and cannot fly high. Swallows also fly low in order to prey on them. Therefore, there is a folk saying that "it will rain when swallows fly low".

Ants move. Swallows fly low.

Swallows, low-flying, small fish come ashore.

You have some people who don't have you who have coaches outside.

Ants move, rainbows, swallows fly low, and small fish appear on the surface.

My life is such an important ......lies in him.

Why do trees grow by people?

To die is to feel the economic crisis.

I don't know how you can still have sweet potatoes, you can eat, I'll tell.

Why do stars blink?

Why is there a rainbow hanging in the sky after the rain?

Why does the sun rise in the east?

None other than Hindenburg, North Lake, Canada.

Electric eels can generate electricity and hypnotize other fish to hunt octopuses
