A joke asking about geography.

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

The student replied, "Heat expands and cold contracts."

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

Wang Hui said: "For example, summer is very hot, so the days are very long;" It's cold in winter, so the days are short. This is the reason why it expands with heat and contracts with cold. "

The students burst out laughing. Why?

2。 Milk on the map

It was hot, and my mother asked Shine Wong to put the milk in the refrigerator, but Shine Wong found a map of the world from her desk, spread it out on the table, and then put a bottle of milk in the Antarctic area of the map.

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 around minus 25 degrees and a minimum temperature of below minus 88 degrees. It is found that the biscuits and cans left by explorers decades ago are not bad at all. If the milk is put there, the insurance won't break. It is much lower than the refrigerator temperature. "

3。 First then

One thunderstorm night, after the lightning, the thunder was loud.

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

Wang Hui proudly said, "I don't understand this either, because my eyes are in front and my ears are in the back. Of course, the eyes look first and the ears listen later. "

4。 Where are the stars?

At night, the stars twinkle in the sky. Brother suddenly asked, "Brother Hui, you can see so many stars at night, why can't you see them during the day?"

Wang Hui said, "That's not easy." He clenched his fist. "This is the earth, this is the stars. As soon as the earth rotates, the star goes around the earth. How can I see it? "

5。 torrential rain

Once upon a time, two people had never seen hail. One day, the sky suddenly began to hail. They all feel strange. One asked, "What is falling from the sky?"

The other said, "It's raining hard."

6。 How crowded the moon is.

When talking about the situation on the moon, the geography teacher said, "The moon is very big and spacious, and it can accommodate millions of people."

Student Yang Liang laughed.

The teacher asked strangely, "What are you laughing at?"

Yang Liang said, "Teacher, you don't know how crowded people living on the moon will be when the moon becomes a bud."

7。 This is London, England

Wang Hui was on the bus and heard two people talking.

The tall man said, "Please tell me something about Jack London." The short man hasn't had time to answer. Wang Hui fought back a smile and said, "Uncle. Not London, Czech Republic, but London, England. "

8。 hang upside down

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

My brother said, "Of course it's on the ground, hanging upside down."

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

Brother said, "They must not leave the ground when they walk, or 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 go around the sun?"

Dad said, "Of course."

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

10。 Where is the source of Hanshui River?

In geography class, the teacher said, "Last class talked about the origin of the Yangtze River and its main tributaries. Who can remember where Hanshui, a tributary of the Yangtze River, originated? "

Wang Hui was absent-minded and didn't hear the teacher's question. But the teacher asked him to answer, and Wang Hui was full of sweat.

Seeing his silence, the teacher asked, "Where is the origin of Hanshui?"

"Khan? Sweat originates from the head! "

1 1。 Erlang Mountain is the highest.

In geography class, the teacher said, "The highest mountain in the world is Mount Everest, with an altitude of 8848 meters."

Wang Hui said, "No, I heard a song two days ago saying that Erlang Mountain is towering high. I calculated that 1 10,000 feet should be more than 30,000 meters, much higher than Mount Everest. "

The answer to "geography joke"

1。 Expand while it is hot

Because geography revolves around the sun obliquely, the northern hemisphere is exposed to sunlight for a short time and a long time in winter, so the days are short and the nights are long. In summer, the northern hemisphere is exposed to the sun for a long time and cannot be exposed for a short time, so the days are long and the nights are short, which has nothing to do with thermal expansion and contraction.

2。 Milk on the map

The South Pole on the map can't replace the real South Pole.

3。 First then

People see lightning first and then hear thunder because the speed of light is fast, 300 thousand 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 are the stars?

You can't see the stars during the day, not because all the stars turn to the back of the earth, but because the sunlight is brightest during the day, covering up the faint starlight.

5。 torrential rain

Rain is liquid, and hail is solid, which mostly occurs in summer. In summer, the ground is very hot and the air rises strongly. When hot air rises to high altitude, water vapor condenses into small water droplets and then cools to form small ice crystals. After repeated lifting, the particles become bigger and bigger until the air can't hold up and hail falls from the sky.

6。 How crowded the moon is.

The moon changes from a full moon to a moon bud because the size of the bright side of the moon on the earth varies with the position of the moon around the earth. It's not that the size of the moon has changed.

7。 This is London, England

Jack London is an American writer.

8。 hang upside down

The earth is a huge sphere. In space, the earth is surrounded by the sky. It doesn't matter which side is up and which side is down. The earth has a strong attraction. No matter where people are on the earth, their feet are on the ground and their heads are in the sky.

9。 When there is no sun.

The earth moves around the sun, producing four seasons. The rotation of the earth produces the alternation of day and night. It's night when the sun is behind you.

10。 Where is the source of Hanshui River?

Hanshui River originated in the mountainous area in the southwest of Shaanxi Province.

1 1。 Erlang Mountain is the highest.

Mount Everest is the highest mountain in the world, with an altitude of 8848 meters. Erlangshan is an adjective and an artistic exaggeration. Erlang Mountain is only 1800 meters above sea level.
