Who knows some funny geography facts?

1. Thermal expansion and contraction

In geography class, the teacher asked: "What will happen to general objects when they are cold or hot?"

Students answered Said: "Thermal expansion and contraction."

The teacher nodded and said: "Yes, who can give an example?"

Wang Hui said: "For example, it is very hot in summer, so during the day It's very long; it's very cold in winter, so the days are very short. This is due to thermal expansion and contraction."

The students burst into laughter. Why?

2. Milk on the map

The weather was hot, and his mother asked Wang Hui to put the milk in the refrigerator, but Wang Hui found a world map from the desk and spread it out. Lay it flat on the table and place the bottle of milk in the South Pole area of ??the map.

My mother asked: "Why did you put the milk on the map?"

Wang Hui explained: "Antarctica is the coldest region in the world, with an average annual temperature of about minus 25 degrees Celsius. The lowest temperature was minus 88 degrees Celsius, and people found that the cookies and cans left by explorers decades ago were not bad at all. The temperature of the milk was much lower than that of the refrigerator.

3. First and last

On a thunderstorm night, after lightning, there was a thunder.

My younger brother asked: "Brother Hui. Why do you always see lightning first and then hear thunder?"

Wang Hui said: "That's not easy." He clenched his hands into fists, "This It’s the earth, it’s the stars. When the earth rotates, the stars go behind the earth. How can we see it? ”

5. It rains hard

Once upon a time, there were two stars. I have never seen hail before. One day, a hail suddenly fell from the sky. They both felt strange. One asked: "What is falling from the sky?"

The other said: "What is falling from the sky?" Hard rain."

6. How crowded is the moon?

The geography teacher said when talking about the situation on the moon: "The moon is very big, and millions of people live on it. Spacious."

Student Yang Liang suddenly laughed.

8. Hanging upside down

My younger brother asked: "Brother, the earth is spherical, where we stand How do people on the other side of the earth stand?"

The elder brother said: "Of course they have their feet on the ground and their heads are hanging upside down."

The younger brother said: "How do they walk? ?"

The elder brother said: "They must not leave the ground with their feet, otherwise they will fall."

The younger brother said: "Fortunately we are on the earth."

9. When there is no sun

Wang Hui asked his father: "Does the earth really revolve around the sun?"

Dad said: "Of course."

Wang Hui asked: "So, what about when there is no sun?"

10. Where does the Han River originate?

The teacher in the geography class said: "The last class taught us about the origin of the Yangtze River and its several major tributaries. Who still remembers where the Han River, a tributary of the Yangtze River, originates?"

Wang Hui was distracted and didn't hear the teacher's question. But the teacher asked him to answer, and Wang Hui was so anxious that he was sweating profusely.

Seeing that he was silent, the teacher asked again: "Where does the Han River originate?"

"Sweat? Sweat originates from the head!"

11. Erlang Mountain is the highest

In geography class, the teacher said: "The highest peak in the world is Mount Everest, with an altitude of 8,848 meters."

Wang Hui said: " No. I heard a song two days ago saying: Erlang Mountain is ten thousand feet high. I calculated that it is more than thirty thousand meters tall. It is much higher than Mount Everest."

"Geography" Answer to "Joke"

1. Thermal expansion and contraction

Due to the tilted geography of the sun's revolution, in winter, the northern hemisphere is exposed to sunlight for a short time and is not exposed to sunlight for a long time, so The days are short and the nights are long. In summer, the northern hemisphere is exposed to sunlight for a long time and is out of the sun for a short time. Therefore, the length of the day and the length of the night have nothing to do with thermal expansion and contraction.

2. Milk on the map

The Antarctic on the map cannot replace the real Antarctica.

3. First and last

The reason why people see the flash first and then hear the thunder is because the speed of light is fast, 300,000 kilometers per second. The speed of sound is slow, only 340 meters per second, not because the eyes are in front and the ears are behind.

4. Where have the stars gone?

You cannot see the stars during the day, not because the stars have all turned to the back of the earth, but because the sun is the brightest during the day, covering up the faint starlight.

5. Hard rain

Rain is liquid and hail is solid. It mostly occurs in summer. In summer, the ground is very hot and the air rises strongly. When hot air rises to high altitudes, water vapor condenses into small water droplets, which then cool to form small ice crystals. After repeated lifting and lowering, the particles become larger and larger until the air cannot support them, and hail falls from the sky.

6. How crowded is the moon?

The reason why the moon changes from a full moon to a moon bud is due to the difference in the moon's orbit around the earth. The size of the bright side of the moon when seen on the earth is different. . It's not that the size of the moon has changed.

7. London, England

Jack London is an American writer.

8. Hanging upside down

The earth is a huge sphere. In the universe, the earth is surrounded by sky. It doesn’t matter which side is up and which side is down. The earth has Powerful attraction. No matter where a person is on the earth, his feet are on the ground and his head is in the sky.

9. When there is no sun

The earth rotates around the sun, causing the seasons to change. The Earth's rotation produces the alternation of day and night. When the sun is behind you, it is night.

10. Where does the Han River originate?

The Han River originates from the mountains in southwestern Shaanxi Province.

11. Erlang Mountain is the highest

Mount Everest is the highest peak in the world, with an altitude of 8848 meters. Erlang Mountain is an adjective, which is an artistic exaggeration. The altitude of Erlang Mountain is only 1,800 meters
